Good Birding Report: London, Ontario
May 6 – 13, 2016

tan - Good Birding Report: London, Ontario <br> May 6 - 13, 2016 — **Observing two male Scarlet Tanagers while birding at the Westminster Ponds ESA was a highlight for me this past week**.

It was another fantastic week birding in the Forest City with a steady increase in migrants, including many more first of year species observed. The week started out with firsts of Baltimore Orioles, Rose-breasted Grosbeaks, as well as Warbling Vireos, and a single Magnolia Warbler observed at Greenway Park. While warbler numbers have been increasing steadily to this point, I still wasn’t observing a tremendous variety with Yellow, Palm, and Yellow-rumped being the most abundant. I knew it was only a matter of time before the migration flood gates opened.

wv - Good Birding Report: London, Ontario <br> May 6 - 13, 2016 — **First of year Warbling Vireos were observed in good numbers earlier this week in Greenway Park**.

When I woke up Wednesday morning and looked out into my backyard, I was happy to see seven Rose-breasted Grosbeaks at my feeder gorging themselves on safflower seed. I knew a significant number of birds must have been on the move the previous night, and was excited to get out birding. Hoping to see the variety of warblers I have been so patiently waiting for, I decided to check out the Westminster Ponds ESA.

magnolia - Good Birding Report: London, Ontario <br> May 6 - 13, 2016 — **Magnolia Warbler**

Located in the city’s south end, this 200 hectare parcel of land is great for birding year round, but is especially good for observing warblers during spring migration. The morning sunrise quickly gave way to overcast skies and a strong east wind. Fortunately, there are many protected areas within the ESA that I expected would be holding good numbers of warblers and other recent migrants.

btb - Good Birding Report: London, Ontario <br> May 6 - 13, 2016 — **Black-throated Blue Warbler**

After arriving at the ponds I followed a line of shrubs at the edge of a field protected from the east wind. Immediately I heard the call of an Indigo Bunting. I scanned the area and could see the bird calling from a tall perch. Unfortunately the bird flew before I could get into a position for a photograph. Making my way along the field edge, I entered the forest to see what else was present. Along a row of tall Spruce Trees an American Redstart, Black-throated Blue Warbler, and Red-eyed Vireo were all observed foraging high within the branches, three first of year species for me.

bg - Good Birding Report: London, Ontario <br> May 6 - 13, 2016 — **Blue-gray Gnatcatcher**

As I made my way around the ESA, Hermit Thrushes could be observed sifting through the leaves on the forest floor as they searched for food. Downy and Hairy Woodpeckers were seen, as the calls of both Red-bellied and Pileated Woodpeckers echoed throughout the forest. Blue-gray Gnatcatchers flitted through the tree tops while orioles and grosbeaks could be seen and heard.

bw - Good Birding Report: London, Ontario <br> May 6 - 13, 2016 — **Blackburnian Warbler**

Arriving on the south side of Saunders Pond, more warblers came into view. Chestnut-sided, Nashville, and Blackburnian were all observed in this area. Again, all first of year species for me. Rounding out my list of warblers for the day was one for my life list, the Northern Parula, with four of these birds being observed. These birds were very high in the canopy and I was unable to capture any photos. However, the sight of these birds was an incredible experience.

csw - Good Birding Report: London, Ontario <br> May 6 - 13, 2016 — **Chestnut-sided Warbler**

Three more first of year birds were observed before I wrapped up my day, as a Gray Catbird, Great-crested Flycatcher, and two vibrant male Scarlet Tanagers came into view in the northeast portion of the ESA. In total, 51 bird species were observed on this day, including nine warbler species. A return trip to Westminster Ponds ESA on Friday yielded many of the same birds, plus a male Eastern Bluebird.

ebb - Good Birding Report: London, Ontario <br> May 6 - 13, 2016 — **Eastern Bluebird**

ger - Good Birding Report: London, Ontario <br> May 6 - 13, 2016 — **Scarlet Tanager**

According to area reports, excellent birding took place this week from various locations within the city and Southwestern Ontario. Komoka Provincial Park had great numbers of birds, and the report from the 2016 Festival of Birds at Point Pelee National Park read, “The warblers were dripping from the trees.”

y - Good Birding Report: London, Ontario <br> May 6 - 13, 2016 — **The Yellow Warbler is one of the more common warblers found in our area**.

My recommendations for areas to bird this weekend would be any of London’s ESAs including Westminster Ponds. Kilally Meadows and Meadowlilly Woods are also favourites of mine. Their mixed habitat and close proximity to the Thames River make them great birding locations. City parks along the Thames River are also prime locations to find migratory birds, as many birds follow the river valley during migration. Gibbons, Greenway, and Springbank are three that I regularly visit and have success at.

rbgb - Good Birding Report: London, Ontario <br> May 6 - 13, 2016 — **Rose-breasted Grosbeaks are one of the birds I most look forward to returning to our area each spring**.

If you are contemplating heading out birding this weekend, I highly recommend it. We are in for some cooler temperatures, but there will still be an abundance of birds present. Things definitely picked up mid-week and great opportunities exist for those heading out. Regardless of where you decide to visit, there will certainly be plenty to see.

Good birding,
Paul

Warbler Migration Heats Up In The Forest City

Each spring many birders, myself included, anxiously await the return of warblers to our area. These small songbirds are some of the most colourful birds to grace our area, yet are also some of the most challenging to identify. The first of May is a date I watch for on my calendar, as this is when we can expect to see warblers return to Southwestern Ontario in good numbers.

yw - Warbler Migration Heats Up In The Forest City — **Yellow Warblers can be seen and heard throughout many of London’s parks and ESAs**.

While birding in several locations over the past week, I saw a significant increase in the number of warblers present each day I was out. Three species continue to be the most abundant: Yellow, Yellow-rumped and Palm Warblers. I have been observing good numbers of these birds throughout the city, with numbers steadily increasing.

yrw - Warbler Migration Heats Up In The Forest City — **This Yellow-rumped Warbler clearly displays the yellow rump for which they are named. The black mask indicates that this bird is a male**.

Other warbler species I have observed include: Magnolia, Pine, and Black and White. Sightings of Blackburnian, Black-throated Green, and Northern Parula have also been reported from within the city.

Palm Warbler - Warbler Migration Heats Up In The Forest City — **Palm Warbler**

City parks and ESAs are where I focused my efforts this past week, concentrating on the edges of wooded areas containing small trees and shrubs. Mornings are always when I have the most success locating warblers. Since warblers migrate at night, early morning is when these birds are most active; feeding heavily as they replenish energy spent the previous night.

yellow warbnler - Warbler Migration Heats Up In The Forest City — **Yellow Warbler**

I have been paying close attention to the daily reports from the 2016 Festival of Birds at Point Pelee National Park. So far, 25 warbler species have been reported from within the park, which is low compared to previous years. The lack of clear nights and south winds could be contributing to these low numbers. Fortunately, this means many more warblers will be making their way through the city in the coming weeks.

Watermark - Warbler Migration Heats Up In The Forest City — **The absence of a black mask indicates that this Yellow-rumped Warbler is a female**.

When searching for warblers be sure you position yourself out of the wind. These sheltered areas are where insects will be most abundant, therefore attracting the highest concentration of warblers. When you come across an area rich with warblers, stay in that location; large concentrations of birds are often found within small areas. Some of our ESAs are hundreds of hectares in size, but many of the areas where I locate the largest number of warblers are often only 20 yards in length and 10 yards wide. Once you locate a high concentration of warblers, find an open area with pockets of light shining in. This will make for unobstructed views and optimal photos.

olia - Warbler Migration Heats Up In The Forest City — **By avoiding sudden movements this Magnolia Warbler did not perceive me as a threat and continued to sing from a thicket**.

When I locate a warbler, but cannot manage a clear view or unobstructed photograph, I stand still and study its behaviour. By not making any sudden movements, the bird doesn’t view me as a threat and becomes accustomed to my presence. I can then see its direction of travel, anticipate its movements, and put myself in a position to get a clear view and photograph. This technique does not require a lot of patience, and I am often rewarded within a few minutes. So often I see others chasing birds around, only to stress and scare them off.

Yellows - Warbler Migration Heats Up In The Forest City — **No only do male Yellow Warblers display rusty breast streaks, they are more vividly coloured than the females**.

The coming weeks will present opportune times for warbler viewing in our area. Pay close attention to the weather forecast; look for clear skies and south winds overnight. The mornings following these conditions can be the best ones to head out. Grab your binoculars, field guide, camera, and make your way to your favourite natural area. The warblers will be waiting for you.

Good birding,
Paul

Stormwater Management Ponds:
Often Overlooked Birding Hotspots

gbh - Stormwater Management Ponds: <br> Often Overlooked Birding Hotspots — **Great Blue Herons are among the many birds you can expect to observe while birding around a stormwater management pond**.

Stormwater management ponds are located throughout large cities and can be found in residential, commercial, and industrial areas. These human-made ponds and their adjacent habitats are often overlooked as birding hotspots. Last week, after receiving a tip from a blog subscriber, I decided to check out a stormwater management pond that I had not yet visited, and was rewarded with great views of a variety of birds.

rwbb - Stormwater Management Ponds: <br> Often Overlooked Birding Hotspots — **Female Red-winged Blackbird**.

The pond I visited is located in the northwest part of London, Ontario in the area known as Hyde Park. I accessed the area from Gainsborough Road, where there is a small area for parking. Upon exiting my truck, I immediately heard the calls of the Red-winged Blackbird and American Robin. Grabbing my camera and binoculars, I headed north along the paved path. On each side of the path was a narrow meadow-like habitat consisting of mixed grasses and small shrubs. Hearing rustling to my right, I turned to look, and from the dried stalks of grass appeared an Eastern Cottontail. Further down the path a small pond came into view, with a wooded area on either side. I was eager to see what species I might encounter next.

ec - Stormwater Management Ponds: <br> Often Overlooked Birding Hotspots — **This Eastern Cottontail was the only mammal species I observed on this day**.

As I continued on, a Northern Flicker could be heard calling and drumming from the woodlot to the east, as an Osprey circled the pond. The small shrubs lining either side of the path contained several Field Sparrows. I’m sure anyone who recognizes the song of the Field Sparrow will agree, it is a lovely trilling sound. Other sparrow species observed around the area were Song and White-throated, both singing beautiful songs of their own. Eastern Phoebes could be seen flying within the meadow, briefly landing on the grass stalks.

song - Stormwater Management Ponds: <br> Often Overlooked Birding Hotspots — **Song Sparrow**.

ep - Stormwater Management Ponds: <br> Often Overlooked Birding Hotspots — **Eastern Phoebe**.

I watched as the Osprey hovered over the pond, and anticipated this bird to plunge into the water after a fish. Unfortunately, this didn’t happen. The large raptor banked to the east and disappeared over the treeline. The rattling call of a Belted Kingfisher echoed over the pond as it moved about the small trees that circle the area. On the far bank I could see a Great Blue Heron wading in the shallow water. As I made my way around the pond, it became clear that this bird was more fixated with what was below the surface than it was on my presence. I raised my camera as it slowly stalked its prey. With a quick strike and a large splash, the heron captured something. Whatever the prey was, it was not visible to me and was immediately consumed as the bird threw back its head.

blue - Stormwater Management Ponds: <br> Often Overlooked Birding Hotspots — **Great Blue Heron capturing a meal**.

At the water’s edge I could see movement. I raised my binoculars to see a Spotted Sandpiper running along the muddy bank, while a Killdeer called not too far away. Scanning the bank with my binoculars, the Killdeer quickly came into view.. These and other small shorebirds blend in extremely well with their surroundings and can easily go overlooked without the aid of a pair of binoculars. I watched and listened as three Greater Yellowlegs circled overhead, but these birds must have been aware of my presence and continued north.

heron - Stormwater Management Ponds: <br> Often Overlooked Birding Hotspots — **In the blink of an eye, a Great Blue Heron can capture and consume its prey**.

Bank, Barn, and Tree Swallows were all observed darting over the pond while feeding on insects. Surprisingly, waterfowl was almost nonexistent with only a few Mallards and pair of Canada Geese present. Quite often during migration, stormwater management ponds are popular stopover areas for a variety of migrating waterfowl. In total 19 species were observed on this day, which made for a rewarding morning.

kill - Stormwater Management Ponds: <br> Often Overlooked Birding Hotspots — **Killdeer and other shorebirds blend in extremely well with their surroundings. Watching for movement and scanning the bank with binoculars is often the best way to locate them**.

Stormwater management ponds are easily found by searching Google maps. These online maps will show the pond itself plus any access points. Be aware that some of these ponds may not be on municipal property, or access may be restricted. Please be sure to obey the rules of any posted signage at the pond you visit.

sandy - Stormwater Management Ponds: <br> Often Overlooked Birding Hotspots — **Spotted Sandpiper**.

Spring migration can be one of the best times of the year to view a variety of birds at one of these habitats. I am a huge fan of shorebirds and these ponds can be one of the best locations to view these birds close to home. It has been at stormwater management ponds that I have achieved some of my best views of Great Egrets in our area during migration. If you have never birded around a stormwater management pond, I highly recommend visiting one in your area.

Good birding,
Paul

Good Birding Report: London, Ontario
April 21 – 29, 2016

yrw - Good Birding Report: London, Ontario <br> April 21 - 29, 2016 — **The Yellow-rumped Warbler is the first of the warblers to return to our area each spring**.

Late April and early May is my absolute favourite time of year to get out birding. It is an exciting time of year as spring migration starts to pick up, and we birders see an incredible number of first of year species. Each time I venture out, I know there is the possibility to see a bird that I have not seen since last fall. This is what motivates me, and can often keep me out in the field for hours at a time. This past week did not disappoint, as I observed many first of year species, and of course many of the ones I had previously observed this year.

pw - Good Birding Report: London, Ontario <br> April 21 - 29, 2016 — **Late April and early May is when many migratory birds return to our area including the Palm Warbler**.

The week started out with my first warbler of the year. It came as no surprise it was a Yellow-rumped. These birds have the shortest migration distance to reach our area of any warbler and are always the first to return each spring. Other warblers observed this past week included: Pine, Yellow, and Palm. All in all it was a pretty good week for warblers given it is still the end of April. Expect the number and variety of warblers to increase substantially over the coming weeks. The lack of leaf cover currently on the trees makes finding and photographing these small, fast moving birds less of challenge.

tree - Good Birding Report: London, Ontario <br> April 21 - 29, 2016 — **I have been observing Tree Swallows in our area for several weeks now, including this pair I photographed today** .

Other than Tree Swallows, I had not observed any other swallows to date until this week. I am happy to report that Northern Rough-winged, Bank, and Barn Swallows have all returned to the Forest City. It is especially great to see Bank and Barn Swallows as these birds are currently listed as at risk in Ontario. The quick aerial maneuvers of any swallow are a treat to watch as they capture insects on the fly.

rws - Good Birding Report: London, Ontario <br> April 21 - 29, 2016 — **Northern Rough-winged Swallow in flight**.

Other first of year species for me this week were the Blue-gray Gnatcatcher and Blue-headed Vireo. Blue-gray Gnatcatchers can be a tricky bird to locate, but fortunately their nasally zee call will help give away their location. If you hear their call, look up as these birds typically forage on insects high overhead. Blue-headed Vireos are the first of the vireos to return each year and can be found in the same deciduous habitats as warblers and gnatcatchers.

gc - Good Birding Report: London, Ontario <br> April 21 - 29, 2016 — **For me listening for the call of the Blue-gray Gnatcatcher is the easiest way to locate this bird**.

Watermark - Good Birding Report: London, Ontario <br> April 21 - 29, 2016 — **Among the vireos, the Blue-headed Vireo is the first to appear in late April**.

A few first of year shorebirds were also observed this past week with the Spotted Sandpiper and Greater Yellowlegs added to my list. While many shorebirds tend to be found along the beaches of the Great Lakes during migration, others are equally at home along small ponds and rivers. Pay close attention to muddy or sandy shorelines along any body of water if you wish to find these birds.

spot - Good Birding Report: London, Ontario <br> April 21 - 29, 2016 — **The Spotted Sandpiper, a small shorebird, can be found along riverbanks and pond edges throughout our area**.

I am still waiting to see my first Baltimore Oriole and Ruby-throated Hummingbird of the year. I have heard several reports of them in our immediate area, but they have eluded me so far. If you haven’t already, make sure both your oriole and hummingbird feeders are out, and the nectar is fresh. These birds will show up in good numbers any day now. Rose-breasted Grosbeaks, another spring favourite of birders and non-birders alike, have been reported in our area, but I have not laid eyes on one yet. Grosbeaks are particularly fond of both black oil sunflower and safflower seed, so keep your feeders full. Like orioles and hummingbirds, grosbeak numbers will increase any day now.

Saturday looks like a beautiful day to get out birding and there are many great places within the city to bird. Remember a few things before you head out. Most of these returning birds consume insects, so look for them where food is abundant. I have the greatest success locating these birds in protected areas out of the wind, where there is the highest concentration of insects. Birds are most active first thing in the morning, making this the best time to head out.

palm - Good Birding Report: London, Ontario <br> April 21 - 29, 2016 — **Palm Warbler**

Birds typically migrate at night, with many of these migrants actively feeding at first light to replenish spent energy after their long journey. With this in mind, carefully plan your route before heading out. If you have the option to, start at the east end of the trail and walk west. This will put the sun at your back, illuminating the birds and avoiding silhouettes. This makes observation and identification much easier, and provides the best light for photographs.

We are in for some great birding action over the coming weeks. If you get the opportunity, head to your favourite park, ESA, or other natural area, and take in the beautiful sights and sounds of spring migration.

Good birding,
Paul

Provide A Home For Cavity Nesters

Cavity nesting birds come in all shapes and sizes. Small songbirds, medium sized ducks, and even large birds of prey make up the 85 North American species that nest in tree cavities. These birds excavate their own holes, use holes excavated by other species, or use naturally occurring cavities that have resulted from decaying trees. You may have seen woodpeckers in early spring excavating their own cavities, while wood ducks, flycatchers, and owls use existing cavities.

fly - Provide A Home For Cavity Nesters — **Great Crested Flycatchers prefer to nest in natural cavities, but will use an old woodpecker hole or nest box**.

Several cavity nesting birds have seen their numbers decrease in recent years, with habitat loss being a contributing factor. As trees are cleared to make way for development, so too are potential nest sites for these and other bird species. In many of our ESAs, city parks, and neighbourhoods, dead trees and limbs are removed due to safety concerns further reducing potential nest sites.

bcc - Provide A Home For Cavity Nesters — **Black-capped Chickadees are another species that excavate their own cavity. I photographed this bird as it excited a decaying willow branch with a beak full of wood**.

Some of the more common backyard cavity nesting birds found in our area are: woodpeckers, wrens, chickadees, and nuthatches. Depending on the habitat of your yard you may also find: swallows, bluebirds, ducks, and even owls nesting in cavities on your property. If your yard lacks dead, decaying limbs or you have removed them for safety reasons, many of these cavity nesters will readily accept a properly placed nest box of the appropriate size.

Watermark5 - Provide A Home For Cavity Nesters — **The Eastern Screech Owl nests in natural cavities or one previously excavated by a woodpecker. These small birds of prey will also use a nest box of the correct size**.

I like to make my own nest boxes with materials purchased from my local building supply store. Boxes are easy to make and the supplies needed are inexpensive to purchase. I have had great luck attracting cavity nesters to my yard following the free plans provided at 50 Birds.com. I find it incredibly rewarding to watch birds nest in a box that I made with my own hands. If you do not have access to tools, or just prefer the convenience of a ready made box that only requires hanging, nest boxes can be purchased from the same local independent retailer where you purchase your seed.

rbw - Provide A Home For Cavity Nesters — **Red-bellied Woodpecker peeking out of a tree cavity**.

Now that the spring weather has finally arrived, cavity nesters are busy searching for potential nest locations. Survey your yard for any dead trees or limbs, assess any potential danger, and if safe to do so contemplate leaving them. If they have to be removed, or you have previously removed them, consider adding nest boxes to provide potential nest sites for any displaced cavity nesters.

Good birding,
Paul

Male Redhead Provides Excellent Views

For area birders, Springbank Park located in London’s west end is a popular destination. The mixed habitat and adjacent Thames River provide the perfect environment for a wide variety of birds, including waterfowl. When local lakes and ponds freeze, a large number of ducks and geese can be observed on the river within the park as it is often the only source of open water in the area.

With Great Lakes ice coverage not nearly what it has been the previous two winters, many expected far fewer ducks on the river this winter. Concentrations of ducks have not equaled that of the winters of 2014 and 2015, but local waterfowl enthusiasts, myself included, have still been treated to some spectacular views from within Springbank Park this winter, including a Greater White-fronted Goose and three Harlequin Ducks.

redhead 1 - Male Redhead Provides Excellent Views — **Eye and bill colour are key field marks that distinguish the male Redhead from a male Canvasback**.

Over the weekend, a male Redhead could be observed in the narrow pond that parallels Storybook Gardens. This pond is typically filled with hundreds of Mallards and is often overlooked by some birders that quickly dismiss all ducks on the pond as this abundant dabbler. Those taking the time this weekend to scan the small pond were rewarded with close up views of a beautiful diver, the male Redhead.

Redheads are a medium sized diving duck. Males display a red head, black breast, and grey body. They are similar in appearance to a male Canvasback, but with a traditional duck-shaped head and not the sloping forehead of a Canvasback. Other key field marks to look for on a male Redhead are the bluish-grey bill and yellow-orange eyes. On the male Canvasback, the eyes are red and the bill is black.

redjhead 3 - Male Redhead Provides Excellent Views — **After feeding on aquatic vegetation, the male Redhead exited the pond and began to preen**.

Redheads feed primarily on submerged aquatic vegetation, but will also consume: snails, mussels, insects, and their larvae. I watched this duck on Saturday and Sunday as it dove repeatedly in the small pond, surfacing with aquatic vegetation. The pond seemed to offer adequate food, as the bird appeared to be feeding well.

With above seasonal temperatures on Sunday, Springbank Park was quite busy as it is one of London’s most popular multi-use parks. The male Redhead was not agitated by the constant foot traffic of adults, children, and dogs. After watching this bird feed for several minutes Sunday afternoon, it then climbed up on the bank of the pond where it proceeded to preen and settle in for a nap, unfazed by parkgoers.

male redhead - Male Redhead Provides Excellent Views — **Male Redhead**

If you are wishing to catch a glimpse of this beautiful duck, he was observed in the east end of the pond closest to the old pump house. There is plenty of free parking located at Storybook Gardens, with this small pond being a short walk along the paved pathway to the east. This Redhead was observed all weekend long and will hopefully continue to provide excellent views into next week.

Good birding,

Once Again Harlequin Ducks Make An Appearance On The Thames River

For the second year in a row, Harlequin Ducks have been reported on the Thames River in London Ontario. Last year a single male bird was observed, whereas this this year a trio of these ducks, two males and one female, have been seen on the river. Harlequin Ducks are rare to our area, as over half of the eastern population of these diving ducks overwinter on the Atlantic coast.

These Harlequins were first reported two weeks ago at Springbank Park. Since then, I have spent a considerable amount of time in the area trying to locate these birds. After an unsuccessful first week, I was finally treated to excellent views of the Harlequin Ducks last Sunday, in the stretch of river downstream from the Springbank Dam.

With the unseasonably warm temperatures, a significant amount of runoff has entered the river as the snow melts. This, combined with recent rain, has water levels on the Thames River unusually high for this time of year. As a result, many of the rapids in this section of river are currently under a significant amount of water, altering this preferred habitat of the Harlequin and making locating these birds more challenging.

harl2 - Once Again Harlequin Ducks Make An Appearance On The Thames River — **The near bank provided an adequate current break for the three Harlequin Ducks, allowing me to view them from close range**.

On a visit to Springbank Park with my Dad last weekend, we located the Harlequin Ducks downstream from the dam near the small island in the centre of the river. The ducks were roughly three quarters of the way across the river, drifting downstream quickly with the fast current. We watched as the group of Harlequins made their way across the river through the island, which was predominately underwater, and settled in against the near bank directly in front of us. The ducks appeared to be content using a slight jut in the near bank as a current break and were impervious to our presence. Seeing the three Harlequin Ducks at such a close range was quite exiting as last year’s bird typically stayed to the middle or far side of the river. After taking several several photos, my Dad and I carried on with our walk heading to the west end of the park.

harl3 - Once Again Harlequin Ducks Make An Appearance On The Thames River — **Harlequin Ducks swimming along the near bank.**

On our way back, we watched for the Harlequins in the same stretch of river as we had seen them only minutes earlier. Strangely, we were unable to locate the birds. After carrying on a little further, we noticed the Harlequin Ducks swimming in a line lead by one of the males now slightly upstream from the dam. Not making much headway in the strong current, the three ducks then drifted back through the dam and came to rest once again along the near bank. From here I managed a few more photos as the birds slowly drifted downstream.

I have been out a few times since, and unfortunately have not been able to relocate the three Harlequin Ducks. To my knowledge these birds have only been reported twice, once on February 15 and then again by myself on February 21. With the high water, these birds may not be in the typical areas that we would expect to find Harlequin Ducks, as increased water is flowing over the rapids making these preferred areas almost nonexistent.

harl 4 - Once Again Harlequin Ducks Make An Appearance On The Thames River — **Harlequin Ducks**

If you are heading out this weekend in search of the Harlequin Ducks, be sure to pay close attention to any rapids that you encounter along the river. Keep a close eye for any exposed rocks that may provide a current break or area where these ducks can exit the river. Having said that, don’t discount other types of current breaks including: flooded trees, fallen logs, islands, or bends in the river. With the high water, many of the overwintering diving ducks are associating to these particular areas. Remember too that the Thames is a large river and with such a mild winter to date, there is significantly more open water than in previous years; these ducks could be almost anywhere up or downstream.

bald - Once Again Harlequin Ducks Make An Appearance On The Thames River — **Bald Eagles are among the many birds of prey observed along the Thames River**.

Even if you are unsuccessful locating the Harlequin Ducks, there is always plenty to see along the Thames River. Bald Eagles make regular passes up and down the river and often perch in the tall trees that line the banks. A wide variety of waterfowl is also present, albeit spread out due to the high water. Songbirds are always plentiful along the shrubby, tree-lined banks.

I’m sure many birders will be out again this weekend in search of the rare Harlequin Ducks and other overwintering waterfowl on the Thames River. It has been great seeing and talking with so many of my blog followers along the river over the past few weeks. If you do happen to see me, please stop and say hello. I am always happy to share my observations with fellow birders along the way.

Good birding,
Paul

Greater White-Fronted Goose Observed In West London

Despite having one of the largest ranges of any goose in the world, the Greater White-fronted Goose is less commonly found east of the Mississippi. These geese breed across the tundra far to our north, while typically overwintering in the southern United States, Mexico, and Central America.

On Thursday, a single Greater White-fronted Goose was reported among a large flock of Canada Geese at The Coves and adjacent soccer field behind the German Canadian Club in London, Ontario.

preen - Greater White-Fronted Goose Observed In West London — **By observing from a distance, my presence went unknown to this Greater White-fronted Goose. I watched for several minutes as this bird, rare in our area, preened its feathers.**

Having never seen a Greater White-fronted Goose, I headed out first thing Friday morning in hopes of adding this bird to my life list. After searching unsuccessfully in the area around The Coves where the bird was originally located, I headed down to Springbank Park to meet my Dad for one of our morning walks.

Still hoping to see the Greater White-fronted Goose, I kept a close watch on the various flocks of Canada Geese in the park and on the river. A few minutes into our walk, I observed a small flock of Canada Geese flying upstream over the river. After a quick glance, the flock appeared to contain only Canada Geese. Fortunately, I heard a high pitched call that was not that of a Canada Goose, which caused me to do a double take. Sure enough, the last bird in the flock was a Greater White-fronted Goose.

gwfg - Greater White-Fronted Goose Observed In West London — **Greater White-fronted Goose preparing to set its wings after preening.**

My Dad and I watched as the flock of geese banked over the path and landed on the soccer field in the west end of Springbank Park. I knew from the angle we were at, the morning sun would present challenging shooting conditions, so we circled wide around the field so the sun was behind us. Looking across the field, which contained approximately 200 geese, we could not see the Greater White-fronted Goose. I raised my binoculars and scanned the flock searching for the distinct field marks of the Greater White-fronted Goose, a bright orange bill and feet.

Finally, after scanning roughly half the flock I noticed a single orange leg in the middle of the field. There it was, the Greater White-fronted Goose standing on one leg with its head tucked under its wings. If not actively searching for this bird, it would have gone unnoticed as it blended in quite well with the surrounding Canada Geese.This is the perfect example of why not to dismiss a flock of Canada Geese while out birding. You never know what may be mixed in. Other goose species that are sometimes observed among flocks of Canada Geese are Snow Geese and Ross’s Geese.

sksks - Greater White-Fronted Goose Observed In West London — **Greater White-fronted Goose, Springbank Park London, Ontario**

If you are looking to add a Greater White-fronted Goose to your year or life list, I recommend heading down to Springbank Park this weekend. Please remember this is a rare bird for our area, which has migrated thousands of kilometres and is likely exhausted and hungry. When searching for rare birds, remember to be respectful and keep your distance. Do not approach too closely, this will only put unnecessary stress on the bird and in many cases cause it to fly. Many other birders will most certainly be out this weekend in search of this goose, so please be respectful of them as well. Chasing a bird in order to get flight shot or up close image not only stresses the bird, but can spoil the opportunity for others to observe it. There is an old saying that I live by when out photographing birds and I ask you to keep it in mind when you are out, “If my behaviour changes the bird’s behaviour, than I am too close.”

With more above seasonal temperatures and plenty of sunshine in the forecast, it looks like a beautiful weekend to get out birding. Hopefully you will get the opportunity to head out in search of this and other beautiful birds.

Good birding,
Paul

Late Fall Is A Great Time To Observe Raptors

In Southwestern Ontario raptor migration typically peaks about the third week of September. This is when we experience the highest concentration of hawks moving through the area. Coincidentally, many birders plan day trips to area hawk watching hot spots such as Hawk Cliff or Holiday Beach. In these areas daily raptor counts on peak days can be in the tens of thousands, which is a remarkable sight to see. However, close views are not always achieved as many of these migrating birds pass by high overhead.

red 2 - Late Fall Is A Great Time To Observe Raptors — **Raptors in flight are my favourite subject to photograph. After a brief wait, I was able to photograph this mature Red-tailed Hawk as it took flight.**

Despite the fact that raptor migration has already peaked, there are still great opportunities for viewing hawks, falcons and eagles across the area. In fact, many of the raptors that draw huge numbers of birders out during peak migration can be found throughout Southwestern Ontario year round, albeit in lower concentrations. Late fall is a great time to get out and observe raptors as leafless trees provide unobstructed views of these impressive birds.

Watermark - Late Fall Is A Great Time To Observe Raptors — **Immature Red-tailed Hawk. Note the yellow iris and banded tail.**

One of the most abundant hawks in our area, that also happens to be a year round resident, is the Red-tailed. These large raptors are regularly found on forest edges, and can be readily observed in city parks, ESAs, and even backyards. Red-tailed Hawks prey on a variety of animals, with small mammals making up a large portion of their diet. Mature Red-tailed Hawks are easily identified by their rufous-coloured tails for which they are named. Immature birds can be a bit more difficult to identify, displaying paler tails that feature horizontal bands. To further aid in proper identification, also note the colour of the iris in the bird’s eye. If it is dark in colour, than it is a mature bird and if it is yellow, then the bird is immature.

Watermark1 - Late Fall Is A Great Time To Observe Raptors — **Cooper’s Hawks are abundant throughout Southwestern Ontario. The dark brown plumage and breast streaks combined with the yellow iris indicate this is an immature bird.**

coopers - Late Fall Is A Great Time To Observe Raptors — **This mature Cooper’s Hawk is a regular visitor to my backyard.**

Another common resident raptor found in our area is the Cooper’s Hawk. Though not as big as the Red-tailed, they are equally impressive. These long, slender raptors are agile flyers, and therefore are often found in denser forests than the Red-tailed. Small birds comprise a large portion of the Copper’s Hawk’s diet, which makes them not uncommon visitors to backyards where bird feeders are present. Adults have a grey back with a rusty streaked breast. Immature birds display dark brown plumage on their backs with heavily streaked brown breasts.

sharpie - Late Fall Is A Great Time To Observe Raptors — **The small head, short rounded wings and square tail help differentiate this mature Sharp-shinned Hawk from a Cooper’s.**

The Sharp-shinned Hawk is another raptor commonly found in our area, with a very similar appearance to the Cooper’s Hawk. Differentiating between these two hawks can be incredibly challenging, but there are a few key field marks to look for. The Sharp-shinned is often smaller than the Cooper’s. However, male Cooper’s Hawks and female Sharp-shinned Hawks often overlap in size, so this is not always the best tell. Sharp-shinned Hawks have shorter wings and a shorter square tail. The head and neck of the Sharp-shinned are also proportionately smaller than the Cooper’s.

eagle - Late Fall Is A Great Time To Observe Raptors — **Bald Eagles are becoming more common in Southwestern Ontario. Mature birds are easily separated from other large raptors by their massive size and solid white head and tail feathers.**

One of my favourite raptors to search out at this time of year is the Bald Eagle. As is the case with many raptor species, these birds have slowly rebounded since the ban of the DDT more than forty years ago, but are still listed as at risk in Ontario. With five nests (that I know of) in the London and immediate area, it is not uncommon to find these birds flying up and down the Thames River. Mature Bald Eagles are virtually unmistakable, as no other common area raptor matches them in size or appearance. Look for their massive bodies and wingspans, combined with the distinct solid white head and tail feathers. Immature Bald Eagles can be a little more confusing as their plumage varies considerably from first to fourth year birds. Again their massive size and thick beaks help with proper identification. Bald Eagles feed primarily on fish, which is why we see them in close proximity to the river. Not all fish are live caught, as eagles are opportunistic feeders and will often scavenge for fish or other animals.

ie - Late Fall Is A Great Time To Observe Raptors — **Immature Bald Eagles are often confused with other large raptors due to their varying plumage. The immense size of both their bodies and beaks helps to identify them.**

Photographing birds in flight, particularly raptors, is one of my favourite subjects to focus on. Positioning myself and waiting for an in flight shot of one of these beautiful birds is when I find myself most patient as a photographer. Under no circumstance do I ever intentionally approach a bird too closely in order to flush it for a flight shot. Some of these raptors may be migrants from northern locations that have entered our area to spend the winter months. These migrants are often very hungry and already stressed. There is no need to put added stress on them by approaching too closely. With a little patience, a shot will eventually present itself. There is a saying that I live by when it comes to photographing wildlife, “If my behaviour changes their behaviour, then I am too close.”

5 - Late Fall Is A Great Time To Observe Raptors — **This first year Bald Eagle displays a mostly dark plumage with white under its wings and tail.**

As mentioned previously, raptors can be easier to locate this time of year now that the majority of area trees have lost their leaves. Any of London’s ESAs or city parks along the Thames River are great places to start your search for raptors. Be sure to keep a close watch on the sky for birds soaring high overhead. Pay extra attention for birds perched along forest edges or rows of trees adjacent to a field or other open areas. These forest edges are common locations to find raptors for two reasons. First, they provide a great vantage point of the surrounding open areas where potential prey can be observed. Second, raptors regularly return to these same perches to consume their prey after the catch.

Southwestern Ontario is home to an abundance of raptors that reside in the region year round. Late fall can be an extremely rewarding time of year to get out birding, especially when it comes to observing raptors. The weather too can be very cooperative at this time of year, as we often see plenty of sunshine and comfortable daytime temperatures. I encourage you to grab your binoculars and field guide and head out to your favourite natural area in search of the many beautiful raptors that grace our skies and forests.

Good birding,
Paul

Fall Migration Heats Up In The Forest City

Fall migration is one of the best times of year to get out birding. With such a high concentration of birds moving through the area, there is always plenty to see. This past week we saw a real mix of weather from almost summer-like to winter conditions across the city. Despite the fluctuating weather, fall migration continued as scheduled.

herm - Fall Migration Heats Up In The Forest City — Hermit Thrushes are currently migrating through our area. They can be distinguished from other thrushes by their reddish tail.

Over the past seven days, I observed many of the species we would expect to see moving through the area at this time of year. Thrushes including Hermit, Swainson’s, and Veery were all observed on or near the forest floor in several of the wooded areas I birded. American Robin numbers increased this past week, as it seems many of the birds that breed to our north have made their way into our area. It is hard to pass by a fruit tree right now without hearing a flock of Robins calling back and forth.

ruby - Fall Migration Heats Up In The Forest City — Ruby-crowned Kinglets are currently abundant as they migrate through the Forest City.

Ruby-crowned and Golden-crowned Kinglets are currently migrating through the city in impressive numbers. These birds can be found almost anywhere from backyards to city parks and ESAs. Spotting these tiny songbirds can be tricky, so be sure to pay attention for their constant movements and high pitched calls. Kinglets feed predominantly on insects, but will also eat the seeds of many plants on cooler days when insects are scarce at this time of year. If you are searching for these birds, pay close attention to fields of Goldenrod adjacent to forest edges.

vult - Fall Migration Heats Up In The Forest City — Mid October is when large numbers of Turkey Vultures migrate across Southwestern Ontario.

Raptor species continue to move through our area with Turkey Vultures being the most abundant. These birds soar with their wings raised slightly upward giving them a “V” shape. This, along with their red featherless heads, helps distinguish them from eagles and other large raptors. Several Merlins were observed at various locations within the city including along the Thames River, Westminster Ponds, and in my own Old South neighbourhood.

nash - Fall Migration Heats Up In The Forest City — Nashville Warbler perched in a Crabapple tree.

Despite warbler migration having already peaked, some species are still present in our area. Last week I observed a Nashville Warbler while birding in Greenway Park. One warbler that we expect to see this time of year and later is the Yellow-rumped. In fact, London, Ontario falls within this bird’s winter range, making it the only warbler to winter this far north. While most other warblers consume a strictly insect diet, the Yellow-rumped’s diet changes to fruit and seeds in the fall and winter allowing them survive in our climate. Look for Yellow-rumped Warblers along the banks of the Thames River, and along forest edges where there is an abundance of food in the form of berries and Goldenrod seeds.

yellow - Fall Migration Heats Up In The Forest City — Yellow-rumped Warbler perched adjacent to a field of Goldenrod.

Migrating waterfowl have begun to show up in the city, specifically at Saunders Pond in the Westminster Ponds ESA. I observed a large flock of RIng-necked Ducks on the east side of the pond over the weekend, and a Common Loon in the middle of the pond on Tuesday. Unfortunately, both of these species were too far out for quality photos. Scanning the pond with binoculars to get a better view of the loon revealed American Coots, Wood Ducks, and a Pied-billed Grebe.

rusty - Fall Migration Heats Up In The Forest City — Rusty Blackbird foraging in the swampy habitat at Westminster Ponds ESA.

Rusty Blackbirds were also present at the Westminster Ponds ESA. These birds have experienced one of the largest population declines of any North American songbird. It is estimated that their numbers have dropped by 85-99% in the last forty years. The name Rusty Blackbird describes their winter plumage perfectly, but may not depict how beautiful these birds truly are. The best access point to see the Rusty Blackbirds is from behind Tourist Information on Wellington Road. From there, follow the boardwalk north that runs alongside Saunders Pond.

rusty 2 - Fall Migration Heats Up In The Forest City — Rusty Blackbirds can be found in flooded forests, wet thickets, swamps and marshes during migration. The west side of Saunders Pond in the Westminster Ponds ESA provides this exact habitat.

Dark-eyed Juncos and many of our winter sparrows, including White-throated and White-crowned, have now returned to the area. Many of you may have already seen these birds, as they are frequent visitors to backyard feeders. If you do not get these birds in your yard, you can find them feeding on Goldenrod and other seeds in the same open areas and forest edges where you will find Kinglets and Yellow-rumped Warblers. Sparrows can be incredibly difficult to identify, especially in fall when many of these birds are still displaying their juvenile plumage. Remember to pay special attention to the subtle differences in their field marks to achieve proper identification.

The weather this past week varied incredibly. The one thing that remained fairly consistent was strong winds. I cannot emphasize enough the importance of finding a location out of the wind to improve your birding success. By doing a few minutes of research and selecting a location out of the wind, you will not only stay warmer on the cool days, but you will also find more birds. Birds unnecessarily expend energy by balancing on blowing branches or trying to keep warm in the path of a cold wind. For these reasons, birds will almost always search out protected areas. The temperature difference between a sheltered and non-sheltered area can vary by several degrees at this time of year, and the warmer protected areas are where insect activity will also be the greatest. Insects will always be found on the leeward side of a forest, and consequently so too will the birds that feed on them. Some of the city’s natural areas are hundreds of hectares in size, but by doing your research and finding a food source out of the wind, you can eliminate a lot of area where bird activity will be limited.

crowned - Fall Migration Heats Up In The Forest City — Monday morning’s wet flurries provided the perfect backdrop for this White-crowned Sparrow, a species that recently returned to our area.

Fall migration has brought plenty of great species into the London area. Many of these species will be with us all winter, while others will not. If you get the chance, head to your favourite birding hotspot, or one of the locations I mentioned in this post; use the wind to your advantage and take in all of the beautiful sights and sounds fall birding has to offer.

Good birding,
Paul
