Good Birding Report London, Ontario
May 22-29, 2015

fly - Good Birding Report London, Ontario <br> May 22-29, 2015 — Observing Great Crested Flycatchers often involves looking high up in the canopy of a tree.

Over the past week, birding was quite typical of what we expect across the region in late May. Migration activity has slowed considerably, but great birding opportunities are still available to those who head out. Resident species, and those that have returned to breed in our area, are plentiful and provide birders with some great views.

butt - Good Birding Report London, Ontario <br> May 22-29, 2015 — As we move into late spring and early summer more butterfly species appear. This Black Swallowtail was one of several species I observed this past week.

I decided early in the week to visit Medway Valley ESA in the northwest end of town. Access to this ESA is available at various locations, but I chose the entrance behind the Elsie Perrin Williams Estate. Immediately, I was treated to the sights and sounds of Red-eyed Vireos. Heading down the narrow dirt trail towards the creek revealed two Indigo Buntings, both beautiful males. Further down the trail, Rose-breasted Grosbeaks, Chipping Sparrows, and a Gray Catbird were observed. Once I reached the creek, Barn Swallows could be seen swooping over the water as they fed on insects. A single Belted Kingfisher was perched on a dead limb extending over the creek. As has been the case everywhere I have birded this spring, Yellow Warblers were abundant. A lone Great Blue Heron made its way over the creek with slow but powerful wing beats.

rose - Good Birding Report London, Ontario <br> May 22-29, 2015 — This male Rose-breasted Grosbeak was one of many colourful birds I observed at Medway Valley ESA.

Hoping to see some shorebirds, particularly Whimbrel, I made my way down to Port Stanley, Ontario on the north shore of Lake Erie. My first stop when arriving in town is always the sewage lagoons. As I turned onto Lake Line, an Eastern Bluebird could be seen on a wire overhead. This particular area is a great place to observe these colourful birds. Arriving at the lagoons, both Bank and Barn Swallows could be observed circling the four ponds. The water on the lagoons was quite high, which is less desirable for shorebirds, and only a few Least Sandpipers were observed. Waterfowl species observed on the four lagoons were: Wood Duck, Blue-winged Teal, American Wigeon, Ring-necked Duck, and Ruddy Ducks.

glaucous - Good Birding Report London, Ontario <br> May 22-29, 2015 — This Immature Glaucous Gull, a lifer for me, was observed among a flock of Ring-billed and Herring Gulls on the main beach in Port Stanley, Ontario.

My next stop in Port Stanley was to check the rock break wall, south of Little Beach. Here I found Common Terns, Double Crested Cormorants, and more Least Sandpipers, but unfortunately no Whimbrel. Finally, I headed over to the main beach to see what was present there. No shorebird activity, but several Great Black-backed Gulls, both adults and immatures were observed. While scanning the large flock of Herring and Ring-billed Gulls on the beach, I noticed a large, mostly white gull land. Its immense size and white wing tips indicated it was a Glaucous Gull. These birds are not as common as other gulls in our area as they breed on the high Arctic, but juveniles especially, are known to overwinter on the Great Lakes. I was quite excited by this observation as this was a life bird for me.

mall - Good Birding Report London, Ontario <br> May 22-29, 2015 — Saunders Pond in the Westminster Ponds ESA revealed my first family of Mallards of the season.

Over the week I made multiple visits to the Westminster Ponds ESA, another one of my favourite locations close to home. One notable sighting was a Common Loon observed on Saunders Pond Monday evening. Brown Thrashers, Great Crested Flycatchers, Pileated Woodpeckers, and an Osprey were all observed within the ESA. It was here that I observed my first Mallard ducklings of the season, as a female with four young slipped through the duckweed on the surface of the pond. Shorebirds including Killdeer and Spotted Sandpipers were observed around the small drainage pond behind Parkwood Hospital.

spot - Good Birding Report London, Ontario <br> May 22-29, 2015 — Spotted Sandpiper foraging among the rocks of a small drainage pond behind Parkwood Hospital.

Great birding opportunities exist around Southwestern Ontario despite the fact that we are past the prime of spring migration. Avoid the mid day heat and plan your outings either in the morning or evening to yield best results. Experts are warning of a bad tick season, and mosquito activity definitely picked up this past week, so remember to apply a bug repellant with deet before you make your way into the great outdoors. So often I hear people complain that birding is slow throughout the late spring and summer months. Nothing could be further from the truth. Southwestern Ontario falls well within the year round range or breeding range of hundreds of species, making anytime the perfect time to go birding.

Good birding,

Good Birding Report: London, Ontario
May 8-15, 2015

Watermark13 - Good Birding Report: London, Ontario <br> May 8-15, 2015 — Yellow Warblers are one of the more abundant spring migrants that I have observed this past week.

Birding around the Forest City this past week has been quite productive with several first of year species added to my years list. It didn’t seem to matter where I birded, there was always something to see, and new migrants appearing. Two of the more productive locations I visited this past week were Kilally Meadows ESA and Westminster Ponds ESA.

Watermark14 - Good Birding Report: London, Ontario <br> May 8-15, 2015 — Birding in London, Ontario this spring has revealed many Baltimore Orioles.

Located in the city’s northeast end, Kilally Meadows offers a variety of habitat including: open meadows, low lying swampy areas, and wooded areas; this mixed habitat attracts a wide variety of species. On my visit, 28 species were observed including firsts of Gray Catbird, Rose-breasted Grosbeak, Field Sparrow, and Palm Warbler. As has been the case with most places I’ve birded this spring, Yellow Warblers could be seen and heard, and several Baltimore Orioles were also observed. I found the area in the open meadow with scattered shrubs at the Windermere Road access to be the most productive, but along the river in the forest revealed several resident species including Red-bellied Woodpeckers and Northern Flickers. A Great Blue Heron was observed stalking its prey on this section of the Thames.

Westminster Ponds on the south side of town was where I observed the most birds. Like the other city ESAs, the mixed habitat provides a favourable home to almost any species of bird found in our area. It was here where first of year Brown Thrashers and Swainson’s Thrush were observed. Warbler species observed within the ESA were: Yellow, Yellow-rumped, and Chestnut-sided. Recently, a Prothonotary Warbler was reported to eBird from Westminster Ponds ESA, so keep an eye out for this endangered species if you visit.

Watermark15 - Good Birding Report: London, Ontario <br> May 8-15, 2015 — Not as colouful as our other swallows, Northern Rough-winged Swallows may often go overlooked.

Other Species at Risk that can be observed within the ESA that I came across on my visits this week were the Eastern Meadowlark and Chimney Swift, both currently listed as threatened. As the name suggests, Eastern Meadowlarks prefer an open grassland habitat, and can be seen when entering the ESA from either access point off Commissioners Road. These birds build their nests on the ground making it very important to stick to the marked trails so nests are not disturbed or inadvertently stepped on. Please remember that dogs are to be kept on a leash. Not only is it a rule of London’s ESAs and enforced by Animal Control, it will prevent your dog from disturbing this delicate species as well.

Another notable species that can be found within the Westminster Ponds ESA are Pileated Woodpeckers. These large, crow-sized woodpeckers are quite a sight to see. Listen and look for them around the wooded trails that circle Spettigue Pond in the centre of the ESA.

Watermark12 - Good Birding Report: London, Ontario <br> May 8-15, 2015 — Tree Swallows construct their nests in tree cavities and can observed nesting in parks and ESAs around London.

City parks along the Thames River are also excellent places to bird, with Greenway Park being one of my favourites. Over the years I have submitted several checklists to eBird from this location totaling 86 species. It is great for birding year round, but many migrating species use the river as a corridor, and can be seen as they feed and rest in the various trees and shrubs that line the banks. This past week in Greenway Park I observed my first of year Orchard Oriole. Warblers, vireos, swallows, waterfowl, and birds of prey can all be observed from within the park. Several species including: Yellow Warblers, Red-winged Blackbirds, Northern Flickers, Tree Swallows, Northern Rough-winged Swallows, and of course, Canada Geese, are all nesting in the park.

Watermark11 - Good Birding Report: London, Ontario <br> May 8-15, 2015 — Canada Geese goslings are among the first young birds we observe in spring. Several families can be observed on bodies of water throughout the city.

Next week I hope to check out a few more of London’s beautiful parks and ESAs in an effort to add to my ever growing year and life lists. Currently my year list consists of 123 species, most of which have been observed right here in the Forest City. I hope you get the chance this week to get out and enjoy some of the beautiful species found within our great city.

Good birding,
Paul

Spring Migration Heats Up
Across The Forest City

Watermark 1 6 - Spring Migration Heats Up <br> Across The Forest City — Baltimore Orioles have returned to our area. This male was observed Monday while birding in Greenway Park.

As May arrived, so too did an influx of spring migrants. On May 1, 2015, I observed my first of year Chimney Swifts as they circled the skies overhead. Chimney Swifts are one of many birds that have seen their numbers decline drastically in recent years, and likely go unnoticed by non-birders. These small birds can be observed throughout the day circling high overhead feeding on insects. Learning their chattering call is the best way to locate Chimney Swifts. Once heard, looking up will reveal these Species at Risk. The Chimney Swifts’ call can be heard on the Cornell Lab of Ornithology’s All about Birds website.

More first of year species were observed as I birded local areas throughout the weekend. Firsts of Baltimore Orioles, Warbling Vireos, and Yellow Warblers were all recorded. Other area birders have also reported firsts of Rose-breasted Grosbeaks, Ruby-throated Hummingbirds and Indigo Buntings, although I personally have yet to observe these species this year.

Watermark 1 4 - Spring Migration Heats Up <br> Across The Forest City — Many birders patiently wait all winter for the return of the warblers in spring. Several species, including the Yellow Warbler, can now be observed across the city.

I have mentioned in the past that it is best to leave your backyard feeders up, at least through the migration, if not all year. Birds are fatigued and hungry upon completing their journey, which in some cases see them traveling hundreds, sometimes thousands of kilometers. Offering quality food is a great way to help them replenish spent energy. These colourful species can all be attracted to backyard feeders if they are left up. Rose-breasted Grosbeaks readily eat black oil sunflower and safflower seed, while Indigo Buntings prefer smaller seed such as white millet. Special nectar feeders for both Orioles and Hummingbirds are available at your local seed retailer. Baltimore Orioles will also feed on oranges. Placing orange slices on your feeder or around your yard will often attract these colourful birds. In my experience, Eastern Grey Squirrels also like oranges, so you may want to place them in a location where they are not accessible.

Watermark 1 7 - Spring Migration Heats Up <br> Across The Forest City — Warbling Vireos are among the first of year species I have observed this week while birding in London, Ontario.

Nectar for Orioles and Hummingbirds can be made inexpensively at home using white sugar and water. For Hummingbirds, use a ratio of four parts water to one part sugar (1/4 cup sugar to 1 cup water). Bring the water and sugar to a boil and stir, this will ensure the sugar dissolves. Be sure to let the mixture cool before adding it to your feeder. Nectar should be replaced regularly, especially when the weather warms up, so I recommend making smaller batches. For Orioles, a ratio of 6:1 is recommended, although Orioles are often seen feeding at Hummingbird feeders and do not seem to mind the sweeter nectar.

Watermark 1 8 - Spring Migration Heats Up <br> Across The Forest City — Baltimore Orioles can be attracted to backyards by offering oranges or nectar from special feeders. Female pictured here.

When making your own nectar for either Orioles or Hummingbirds, do not use dyes or food colouring. Dyes and colouring are made from unnatural products and can be harmful to birds. Flower nectar is naturally clear, and Hummingbird and Oriole feeders are specially coloured to attract these birds, without the use of harmful artificially coloured nectar.

Watermark 1 10 - Spring Migration Heats Up <br> Across The Forest City — A lack of leaf cover this spring is making for easier bird viewing.

Early May is a great time to get out and observe many migrating birds as they return and move through our area. Thanks to the cool start this spring, many trees are not yet fully covered in leaves, making viewing these birds even easier. Several species, including Warblers, are often observed high up in trees feeding on insects and the absence of leaves provides excellent views. When birding in a forested area, be sure to observe the forest floor as many wildflowers are now coming into bloom. Bloodroot, Trout Lilies, Mayapples, and the popular Trillium are some of the species that are visible throughout the public forests and ESAs in London.

If you get the chance this week, head out to your favourite park, ESA, conservation area, or be extra observant in your own backyard. Spring migration is heating up and several more species will be visible over the next few weeks.

Good birding,
Paul

Spring Yard Cleanup, It’s For The Birds

Now that spring is upon us and warmer temperatures have finally arrived, many people are heading outdoors to begin their spring yard cleanup. Before you go cutting back and bagging everything that is not green, take a minute to think about the birds.

Spring is when birds begin nesting in our area, and many birds can now be observed rummaging through gardens looking for nest materials. If you are planning on doing some yard cleanup in the near future, consider leaving some materials for the birds. Dry leaves, grass, twigs, and flower stocks are all used by many songbirds to construct a nest. If you are wanting to clear out your garden to expose freshly emerging tulips and daffodils, these materials can be placed in a different area of your yard, where the birds can access them.

Watermark 1 51 - Spring Yard Cleanup, It's For The Birds — **Dead tree branches and stumps around your property will attract woodpeckers like this Northern Flicker and other cavity-nesting birds.**

If you have dead branches on your property, and it is safe to do so, leave these as well. Dead branches serve two purposes: they attract insects, which as a result will attract woodpeckers and other birds; they also provide nest sites for a variety of cavity-nesting birds.

Watermark 1 31 - Spring Yard Cleanup, It's For The Birds — **Black-capped Chickadee excavating a nest cavity in a dead willow tree.**

Many people only feed the birds during the winter months, taking their feeders down once spring arrives. Spring is an equally important time of year to feed the birds as there is not always an abundance of natural foods around. Most of the seeds and berries from last season have long since been consumed, while this year’s crop is months away. Birds returning from their wintering grounds have traveled thousands of kilometers in some cases, and need to replace spent energy.

Leaving your feeder up throughout the migration period will provide these birds with much-needed nourishment. I personally leave my feeders out year-round, because after the migration period, adult birds begin bringing their young to the feeders.

Watermark 1 71 - Spring Yard Cleanup, It's For The Birds — **Placing fruit around your yard is a great way to assist Robins and other non-seed eating birds while natural foods are scarce.**

Since several birds do not regularly accept seed offerings, fruit can be substituted. Robins and Cedar Waxwings can both benefit, especially on cooler days when insects are hard to come by, from fruit placed around your yard. Baltimore Orioles, when they return in a few weeks, will readily accept oranges cut in half or sliced. Make sure the fruit is fresh and has not gone moldy or spoiled.

Spring is a perfect time to make sure your feeders are clean. Washing your feeders regularly with warm water and an eco-friendly dish detergent will help ensure your backyard birds stay healthy by preventing disease. Use an old toothbrush to remove any feces, moldy, or stuck on seed. Rinse your feeder thoroughly and ensure it is completely dry before refilling.

Watermark 1 41 - Spring Yard Cleanup, It's For The Birds — **Leaves, twigs, and various yard materials are gathered by Northern Cardinals and other birds to build nests.**

Fresh water is equally important to birds. If you put your birdbath away last fall, it is time to get it out and fill it up. Clean water is essential, so be sure to change the water regularly. If you have a water feature or fountain in your yard, make sure the water is clean and the pump is running. Resident and migrating birds with both be looking to bathe and drink from the running water. In fact, water is a better attractor of birds than food is. If you don’t already have one, add a birdbath or other water source to your yard if you are wishing to attract more birds.

Watermark 1 62 - Spring Yard Cleanup, It's For The Birds — **Even with a seemingly slow start to spring birds, including the Red-winged Blackbird, are arriving on schedule.**

Despite a winter that seemed like it would never end, and a relatively slow start to spring, bird migration is on schedule. Many of the birds we expect to see by this time have returned. Blackbirds, American Robins, several sparrow species, and swallows have all been observed in our area. This past week I observed my first of year Eastern Phoebe and Hermit Thrush, both right on schedule. Over the next couple of weeks, we will see another big push of songbirds return to our area. Baltimore Orioles, Indigo Buntings, Rose-breasted Grosbeaks, and of course, the warblers will all be arriving. Will your yard be ready to welcome these birds with open arms?

Good birding,
Paul

Barn Swallows Will Soon Be Swarming
The Hive

Watermark 13 - Barn Swallows Will Soon Be Swarming <br> The Hive — The Hive, located in London Ontario, recently installed several Barn Swallow nest platforms around their property.

Currently listed as threatened on the Species at Risk list, Barn Swallows have suffered a population decrease of 65% in recent years. As is the case with all species that make it onto this list, habitat loss is one factor to blame. Barn Swallows prefer an open habitat including city parks, agricultural land, and bodies of water such as rivers, lakes and ponds. As cities grow and land is developed, these open expanses where Barn Swallows live are being destroyed.

Watermark 1 26 - Barn Swallows Will Soon Be Swarming <br> The Hive — This narrow drip edge under a soffit provides enough of a ledge for a Barn Swallow to construct its nest.

Barn Swallows construct their mud nests in a variety of locations, but prefer some type of ledge on a human made structure. Places where Barn Swallows nest include under bridges, eaves troughs, and on top of rafters or beams in sheds and garages. Modern buildings constructed of aluminum or galvanized steel are tightly sealed. This denies Barn Swallows access to their beams and rafters, drastically reducing the number of potential nest sites. If you are a landowner with Barn Swallows on your property, providing these birds with an alternative nesting option is something you can do to help reduce the further decline of this species.

Watermark 1 37 - Barn Swallows Will Soon Be Swarming <br> The Hive — Barn Swallows collect mud to construct their nests. The mud often contains grass and other debris found within the mud. The nests are then lined with grasses and feathers.

While attending BeeFest at The Hive in south London last summer, I noticed several Barn Swallows flying over the open fields of the property. Several of their small mud nests could be seen under the eaves troughs and overhangs of various buildings located on the property.

Watermark 1 53 - Barn Swallows Will Soon Be Swarming <br> The Hive — Barn Swallows, an aerial insectivore, prefer an open habitat that allows them to forage on insects.

Last week I contacted Jenna Goodhand, owner of The Hive, and asked if she would be interested in adding some nest platforms to the sides of the buildings to increase the number of locations where Barn Swallows could build their nests. Knowing the state of these threatened birds, Jenna was more than happy to help out. I was invited out to survey the area and collectively decide where the nest platforms would be best suited.

Watermark 1 48 - Barn Swallows Will Soon Be Swarming <br> The Hive — The overhang on this shed is an ideal location to mount a nest platform under. The narrow ledge of the platform will provide the perfect place for a Barn Swallow to construct its mud nest.

Barn Swallows will reuse the same nest each year, so buildings with sufficient overhangs and ledges and those with nests from last season attached were avoided. It was obvious that the birds were successful here and didn’t require our help. Our focus was on the buildings that had no nests attached. These buildings had great overhangs for nesting under, but lacked a small ledge or suitable surface for the Barn Swallows to attach a mud nest to. Our goal was to install the nest platforms on these buildings to provide more Barn Swallows and future generations of Barn Swallows adequate structures on which to build their nests in hopes of increasing their population. After determining adequate locations, several nest platforms were installed. Jenna and I will be monitoring these platforms throughout the year and I will be adding updates to my blog regarding their success once the birds have returned to the area.

Watermark 1 63 - Barn Swallows Will Soon Be Swarming <br> The Hive — Adding nest platforms to your buildings is something any land owner can do to help this fragile species.

These custom made Barn Swallows nest platforms differ from commercial nest platforms in that the ledge is only 2.5″ wide. This narrow ledge is wide enough for the Barn Swallows to construct their nest, but narrow enough to deter other birds that nest on platforms such as the American Robin or Mourning Dove. Barn Swallow nest platforms should be installed under an overhang on the side of a human made building such as a shed, garage or boathouse; not on a tree or fence post as is the case with nest boxes. Recommended mounting height for the platforms is 7-12 feet off the ground and 5 feet apart. Facing the platforms north or east will ensure they do not get too hot from the afternoon sun. As mentioned, Barn Swallows construct their nests from mud, so positioning the platforms near a garden, shoreline, or other mud source will add to their success.

If you have Barn Swallows on your property, consider adding nest platforms to your buildings to help this delicate species. Providing adequate habitat and sufficient nest sites are easy steps landowners can take to ensure the future of this species. For best results, platforms should be installed before the birds return, so act fast. Barn Swallows, an aerial insectivore, are great birds to have around as they naturally control insect populations. If adding nest platforms is something you are interested in, my previous post Barn Swallows Nest Platforms has more information, including more images and dimensions.

A special thanks to Jenna Goodhand of The Hive for doing her part to help save a Species at Risk. If you wish to follow along throughout the season, subscribe to my blog via email and have new posts including updates from The Hive sent right to your inbox.

Good Birding Report: London, Ontario
March 6-13, 2015

Watermark 1 43 - Good Birding Report: London, Ontario <br> March 6-13, 2015 — Warmer temperatures this past week had several first of year species present across the city, including this Eastern Chipmunk.

The abundance of waterfowl present on the Thames River continues to be what area birders are drawn to and talking about. Thanks to this week’s warmer temperatures, most of the previously ice covered sections of river are now flowing. While this has resulted in a decrease in the concentration of ducks, the variety of species remains impressive. This week I added to my growing list of waterfowl observed this year on the Thames River with: a pair of Wood Ducks, a pair of American Wigeon, a lone Ring-necked Duck, and several American Coots. Although they are more spread out, all of the diving ducks mentioned in previous posts are still present.

Watermark 1 33 - Good Birding Report: London, Ontario <br> March 6-13, 2015 — The variety of dabbling ducks increased on the Thames River this past week. Among the dabblers present are Northern Pintails.

A complete list of waterfowl I observed this past week is as follows:

American Black Duck
American Coot
American Wigeon
Female Common Goldeneye.
Bufflehead
Canada Goose
Canvasback
Common Goldeneye
Common Merganser
Greater Scaup
Harlequin Duck
Hooded Merganser
Lesser Scaup
Long-tailed Duck
Northern Pintail
Mallard
Red-breasted Merganser
Redhead
Ring-necked Duck
White-winged Scoter
Wood Duck

Watermark 1 51 - Good Birding Report: London, Ontario <br> March 6-13, 2015 — Male Harlequin Duck in flight.

For birders along the Thames River, the Harlequin Duck continues to be the big attraction. Everyday as I walk the river, fellow birders can be heard asking each other if they have seen the duck. My last sighting of the Harlequin Duck was Thursday afternoon, upstream of the foot bridge to Thames Valley Golf Course. This bird slowly made his way upriver all week from where it spent so much time previously, downstream from the old pump house. Despite walking the entire stretch of river from the outflow at Greenway Park to the Sanatorium Road bridge on Friday, I was unsuccessful at locating the Harlequin Duck. The last report to eBird, at the time of writing this, had him present in front of the London Canoe Club late Thursday.

Watermark 1 23 - Good Birding Report: London, Ontario <br> March 6-13, 2015 — American Coots are among the variety of waterfowl present on the Thames River.

With warm temperatures and south winds, I expected to see more migrants show up this past week. Although I did read reported sightings in our area, I was surprised not to personally observe any Red-winged Blackbirds or Common Grackles. We should see increased numbers of blackbirds in the coming weeks. While scanning the Thames River for waterfowl at the old pump house, I heard the distinct call of a Killdeer. Looking out over the water I observed the bird fly across and set down on the recently thawed sand bar on the far bank. Watching through binoculars, I could see the Killdeer foraging in the wet sand. I also observed my first Eastern Chipmunks of the year this past week, one in my backyard and two in Springbank Park.

Early spring is an excellent time to get out birding. With so many resident species, plus the overlapping of incoming and outgoing migrants, the variety of birds around at this time of year can be quite impressive. Also, the increased temperatures we are experiencing have made birding conditions more comfortable. Next week is March Break, a great time to get outdoors with kids and introduce them to nature. For those of you not heading south, get out and enjoy the remaining overwintering birds that can be found across the city, and those returning from their wintering grounds.

Good birding,
Paul

Time Is Running Out For Winter Birding

As the days become longer and spring approaches, many of the birds that have been overwintering across our region will begin their migration north. There are currently great opportunities in and around the city to view some incredible species, but with every passing day the window of opportunity narrows. The frigid temperatures are partially responsible for the incredible winter birding we have experienced this winter; not knowing what next winter will bring it is best to act now if there are certain birds you still wish to see.

For the second year in a row, Snowy Owls irrupted throughout Southwestern Ontario including many sightings around London, Ontario. Recent sightings from south of the city in the Manning Drive and Wellington Road area, as well as the Old Victoria Road and Wilton Grove Road area have been reported. This past week I decided to check the area Northwest of Strathroy, a popular wintering area for these Owls, and located two.

If you still need a Snowy Owl for your year or life list, and you are not planning a trip to the Arctic, than I suggest heading out in the next couple of weeks as these birds will be migrating north very soon. Rough-legged Hawks are another raptor to keep an eye out for while driving the back roads. Breeding in the Arctic Tundra and taiga these large birds of prey are only seen in Southwestern Ontario during winter months.

Watermark 1 61 - Time Is Running Out For Winter Birding — Although a year round resident in our area, the Horned Lark is more easily observed against a snow covered background.

While searching for Snowy Owls be sure to keep an eye out for Snow Buntings. These predominantly white birds can be observed at the side of roads and in the fields adjacent to them. Snow Buntings return to their Arctic breeding grounds in early April leaving little time to see them across Southwestern Ontario. Flocks of Horned Larks can also be observed in the same areas as Snow Buntings; these ground birds can be found year round across our area, but are much easier to locate during winter months when the ground is covered in snow.

51 - Time Is Running Out For Winter Birding — Common Redpolls are among the many species that will soon be leaving our area.

Small songbirds including finches like the Common Redpoll and Pine Siskin will soon migrate north. These birds can be seen at backyard feeders feeding on sunflower and nyjer seeds. If your feeders are not being visited by either of these species, I am still observing good numbers of these birds along the banks of the Thames River feeding on Alder catkins. Many overwintering sparrow species including: White-throated, White-crowned, American Tree, and the Dark-eyed Junco will soon be absent from the region as spring approaches.

Watermark 1 81 - Time Is Running Out For Winter Birding — Rare birds such as the Harlequin Duck overwintering on the Thames River potentially offer once in a lifetime views.

Those of you that subscribe to my blog, or follow me on Facebook and Twitter already know what an incredible winter it has been for waterfowl on the Thames River in London, Ontario. With 20 species of waterfowl reported, the banks of the Thames has been popular with birders this winter. Many birders have been walking the banks in search of the Harlequin Duck. This rare duck is only the second ever recorded in Middlesex County, with the last reported in 1968. If you have not yet experienced the beauty of a Harlequin Duck, than I recommend heading down to the river as soon as you can. The eastern population of this duck breeds across Northern Quebec, Labrador, or Southern Baffin Island and is yet another species that will soon be gone.

It is not just the Harlequin Duck that will disappear from the Thames River. Some of the 20 species of waterfowl that will be leaving our area in the near future include: Common Goldeneyes, Greater Scaup, Canvasbacks, and White-winged Scoters.

Watermark 1 9 - Time Is Running Out For Winter Birding — Common Goldeneyes and other diving ducks will soon be leaving the Thames River to return to their breeding grounds to our north.

If there is a species that you are wishing to see this winter, but are not sure where to locate them than consult the eBird species map. This map is a great tool for birders to locate any species around the world, and is easy to use. Simply enter the species you wish to locate, and the location in which you would like to observe it. To narrow your search, select the current year. The map will then display all reported sightings of that particular species. You can then zoom in to see the exact location of all reported sightings nearest you.

Watermark 1 11 - Time Is Running Out For Winter Birding — Irruptions do not typically happen every year. Take advantage of the few remaining weeks of winter to locate and observe some of the wonderful birds that are overwintering in our area.

One key factor that triggers bird migration is the amount of daylight. As the days get longer, overwintering birds will start making their way north to their breeding grounds. Many of these species will likely be leaving within the next couple of weeks. Our clocks go forward this weekend giving us an extra hour of daylight in the evenings to head out birding in search of some of these overwintering species. When it comes to Snowy Owls or the Harlequin Duck, take advantage of daylight savings and make a point to get out and observe these birds. There is no guarantee that these birds will return to our area next winter and present such incredible views.

Good birding,
Paul

Good Birding Report: London, Ontario
February 22- March 1, 2015

Watermark 1 3 - Good Birding Report: London, Ontario <br> February 22- March 1, 2015 — Common Goldeneyes are one of the many species of waterfowl currently overwintering on the Thames River

February departs as the coldest one on record for London, Ontario, but with cold temperatures came great birding opportunities. Once again this winter the volume and variety of waterfowl on the Thames River has been simply spectacular.

This past week I personally observed sixteen species of waterfowl on the river between Springbank and Greenway Parks. The regular overwintering species are all present as well as increasing numbers of the less common visitors. Redheads, Canvasbacks, Long-tailed Ducks, and Red-breasted Mergansers can now be readily observed at various locations on this stretch of river. Among the new arrivals to the river this week were four White-winged Scoters at Greenway Park.

Watermark 1 8 - Good Birding Report: London, Ontario <br> February 22- March 1, 2015 — I watched this Red-breasted Merganser for several minutes as it struggled to swallow a small catfish.

The rare Harlequin Duck that was first reported on February 10 is still present at Springbank Park. According to local records, this is only the second ever Harlequin Duck recorded in Middlesex County with the last sighting in 1968. This really is a rare opportunity to observe one of these ducks close to home. If you haven’t located this bird yet, my last post Harlequin Duck Continues To Elude Some Area Birders offers suggestions on how to go about locating the Harlequin Duck.

Large, mixed flocks of Herring and Ring-billed Gulls were observed on the ice at Greenway Park. Present in this large flock were two Great Black-backed Gulls. Great Black-backed Gulls are the largest gull in the world and are easily identified by their black backs and white underparts. These Gulls are typically found to our northeast, with their year round range extending from Lake Ontario to the Atlantic Coast. Overwintering Great Black-backed Gulls can often be found along the Lake Erie shoreline; like so many other species this winter they have moved inland due to the increased ice coverage on the Great Lakes in search of food.

Watermark 1 5 - Good Birding Report: London, Ontario <br> February 22- March 1, 2015 — From its perch in a Spruce tree, this Red-tailed Hawk patiently waits for prey to appear below.

Raptor activity along the river has been impressive too. Red-tailed Hawks are readily observed soaring high above, as well as lower down perched in trees. Several mammals including Eastern Grey Squirrels have a hard time moving about in deep snow. As a result, many Squirrels are spending a considerable amount of time in and around evergreen trees where the thick branches have prevented snow from reaching the ground. It is here where these mammals forage on the fallen seeds from various cones, as well as peanuts left by park goers.

Red-tailed Hawks are using this as a perfect feeding opportunity. I recently observed these raptors perched 10-15 feet off the ground in the dense cover of the spruce trees. When an unsuspecting squirrel ventured out from under the tree, the Red-tailed Hawk made a short drop onto its prey. These birds appear to be having a much better success rate with this approach than if they were to dive from high above. As a birder and photographer I do not bait birds of prey, and am not leaving peanuts under the trees for the squirrels in an effort to bait the hawks. Other raptors readily observed are Bald Eagles, Cooper’s and Sharp-shinned Hawks.

Watermark 1 - Good Birding Report: London, Ontario <br> February 22- March 1, 2015 — The patchy white feathers on this American Robin indicate it is leucistic.

A large flock of American Robins were located in the west end of Springbank Park next to the dam. These birds could be observed feeding on the berries from the invasive Common Buckthorn tree. Contrary to what many believe, robins are not a sign of spring as Southwestern Ontario falls well within their year round range. Robins are simply less visible during winter months as there diet switches to fruit and berries, and these birds move around frequently in search of food. In years when fruit is less abundant, robins may migrate south. One of the robins in the flock observed was of interest as the white patches on its plumage indicated it was leucistic. Leucism is the loss of pigment which results in these white patches. It differs from albinism in that it is a reduction of multiple pigments not just melanin, and the eye colour is not effected.

Watermark 1 6 - Good Birding Report: London, Ontario <br> February 22- March 1, 2015 — This past week saw an increase in the number of Redheads on the Thames River. These diving ducks feed on aquatic vegetation.

My birding adventures as of late have been limited to Springbank and Greenway Parks. With such a wide variety of birds and the plowed and well packed trails, I have seen little reason to bird anywhere else within the city. As temperatures warm and the snow melts, I look forward to exploring more of my favourite locations and reporting my findings from them.

The time left to view many of these incredible waterfowl species, including the rare Harlequin Duck, so close to home will fade as temperatures increase and spring approaches. Don’t leave it too late or you could miss a once in a lifetime opportunity. Layer up, grab your binoculars or scopes and head down to the Thames River. There is no such thing as a bad day birding along the river. I am quite certain that you too will be impressed with the variety and quantity of waterfowl present on the Thames.

Good birding,
Paul

Rare Harlequin Duck Attracts Birders to London, Ontario

For the second year in a row, the Thames River in London, Ontario has revealed a rare species of waterfowl. Last winter the Thames was briefly visited by two Red-throated Loons, the first two recorded in Middlesex County since 1898.

This winter, another unique visitor has made the Thames River his temporary home. The male Harlequin Duck is easily identified by his slate blue plumage, rusty red sides and white markings. Despite its brilliant colours, from a distance this duck appears quite dark and can be easily overlooked at a quick glance. Once observed, it is difficult to put into words just how beautiful this duck truly is.

Watermark 1 12 - Rare Harlequin Duck Attracts Birders to London, Ontario — Male Harlequin Duck setting its wings after preening on the Thames River.

The Harlequin Duck’s breeding range extends from northern Quebec and Labrador to the southern portion of Baffin Island, while typically wintering off the Atlantic coast. According to the Cornell Lab of Ornithology, more than half of the eastern population of Harlequin Ducks winter in coastal Maine. Harlequin Ducks have been reported in previous years overwintering on the Great Lakes, with occasional sightings coming from Toronto, Burlington, and the Hamilton Harbour areas.

Birders from all over Southwestern Ontario are traveling to London in hopes of getting a glimpse of this rare duck. Over the past couple of weeks I have spoken with fellow birders from Stratford, Wallaceburg, Sarnia, and Waterloo.

Watermark 1 9 - Rare Harlequin Duck Attracts Birders to London, Ontario — Birders are traveling hundreds of kilometers to London,Ontario in hopes of catching a glimpse of the rare Harlequin Duck.

Since it was first reported two weeks ago, the male Harlequin Duck has been observed daily at Springbank Park in London’s west end. If you are hoping to add this duck to your year or life list, than I recommend parking at Storybook Gardens and walking the section of river between Springbank Dam and the old pump house.

Follow the well packed trail in the snow paralleling the bank. While most areas are covered in knee deep snow, this trail is easy to navigate thanks to the heavy foot traffic of all the birders. Be sure to scan both the near and far banks of the river as this duck moves around frequently, and can be a challenge to locate through the dense brush lining the near bank.

The Thames River in London, Ontario is a waterfowl enthusiasts dream. If you are reluctant to make the trip to London just to see the Harlequin Duck, there is plenty of other waterfowl to see. A complete list of waterfowl observed on the Thames River so far this winter is as follows:

American Black Duck
Common (pictured here), Red-breasted, and Hooded Mergansers can all be observed on the Thames River.
Bufflehead
Canada Goose
Canvasback
Common Goldeneye
Common Merganser
Greater Scaup
Harlequin Duck
Hooded Merganser
Horned Grebe
Long-tailed Duck
Mallard
Northern Pintail
Red-breasted Merganser
Redhead
Red-necked Grebe

As was the case last winter, the extremely cold temperatures have the Great Lakes freezing over, leaving diving ducks such as the Harlequin Duck migrating to inland rivers in search of open water. Open water is key to the survival of the Harlequin Duck, as they feed on a variety of aquatic life including: molluscs, crustaceans, fish, and other invertebrates. Harlequin Ducks dive below the surface and use their bills to capture prey from beneath rocks and along the river bottom.

Watermark 1 10 - Rare Harlequin Duck Attracts Birders to London, Ontario — This male Long-tailed Duck was observed slightly downstream from the location where the Harlequin Duck has been frequenting.

Aside from the open water, there is another reason why I believe we are seeing an increase in waterfowl on the Thames River over the past several seasons. Springbank Dam has been non operational since 2008, drastically improving water quality and returning the river to its natural state. As a result, wildlife is thriving in the area. By not damming the river each spring, willows, alders, poplars, and birch trees are all rejuvenating an enlarged riparian zone, an area that with an operational dam would otherwise be underwater.

This naturally reforested riparian zone provides a buffer between humans and waterfowl, giving them a greater sense of security. Allowing the river to flow freely year round improves water quality by preventing algae and sediment from building up on the river bottom. This lack of sediment permits aquatic life to thrive including the crustaceans and invertebrates that many of these diving ducks, including the Harlequin, feed on. An abundance of food, translates to an abundance of ducks. For more on how the Thames River is benefiting without the dam, read my blog post Thames River Much Healthier Without Springbank Dam.

Watermark 13 - Rare Harlequin Duck Attracts Birders to London, Ontario — Horned Grebes are among the waterfowl currently observed on the Thames River at Springbank Park.

When searching for the Harlequin Duck, or other northern waterfowl species on the Thames River, move slowly and quietly up and down the bank. These birds are not as accustomed to humans as the Mallards and Canada Geese are, and can be easily startled. Avoid sudden movements; when searching with binoculars or taking a picture, raise your camera or binoculars slowly to your face. When you do locate the bird and are pointing it out for someone else, raise your arm slowly. Be aware of any noise you may be making, whether crunching snow under your feet or the sound of your clothing brushing against tree branches. These ducks will fly at the slightest movement or unfamiliar sound.

Watermark 1 14 - Rare Harlequin Duck Attracts Birders to London, Ontario — The Harlequin Duck on the Thames River has been associating with a small group of Common Goldeneyes. Be sure to look closely at groups of Goldeneyes when searching for the Harlequin Duck.

Remember to be respectful out there, both of the birds and of other birders. I have been really impressed so far with everyone I’ve seen searching the river for this beautiful duck. No one has attempted to get too close, and all of the birders are working together and assisting others who have not yet observed the Harlequin Duck.

If you get the opportunity this weekend, head down to Springbank Park and get a look at this beautiful Harlequin Duck and all of the other wonderful species overwintering on the Thames River.
