This brightly coloured male Indigo Bunting was observed at Wawanosh Wetlands Conservation Area in Sarnia, Ontario
Early in the week, I found myself in Sarnia, Ontario with a few spare hours, so naturally I sought out somewhere to go birding. I decided to hike the Wawanosh Wetlands Conservation Area located on Blackwell Road in the city’s east end. Despite the name, the area is more than just wetland, with a nice mix of habitat including a large forested area and open meadows. This variety provides perfect habitat for several species. In total, I observed 32 species while hiking the 2.5 km trail. No rarities to report from this area, but I had excellent views of many songbirds including: Indigo Bunting, Red-eyed Vireo, House Wren, and Cedar Waxwings to name a few. If you ever find yourself in Sarnia and looking for a place to bird, I recommend visiting Wawanosh Wetlands Conservation Area.
The highlight of this past week was seeing this Common Loon in the Thames River at Greenway Park.
Back home in London, I birded several city parks along the Thames River this past week. The highlight for me was a single Common Loon observed in the Thames at Greenway Park on Wednesday morning. I figured the loon sighting was worthy of reporting to eBIrd, so I began compiling a list and tallied 35 species in total from this visit. The loon was indeed deemed rare by eBIrd, given the species, location, and/or time of year, and I submitted my photo for confirmation. Other species observed that day can be found on my eBird checklist.
This active Osprey nest at Labatt Park has been used annually for several years.
Further upstream near the forks of the Thames, the Osprey were active near the nest at Labatt Park. When I first arrived a lone bird was sitting on the nest, but it wasn’t long before another adult showed up with a fish in its talons. The morning sun illuminated the birds perfectly against the blue sky. Colonies of Barn and Cliff Swallows are also nesting in the area, with both species being observed flying over the river as they captured insects. Active nests are a positive sign, especially for the Barn Swallow which is a Species at Risk.
This Red-spotted Purple Butterfly nectaring from this viburnum flower was one of many butterflies observed at Westminster Ponds ESA.
Finally, I wrapped up the week birding at Westminster Ponds ESA. For butterfly enthusiasts, activity here was great with sightings of several species including: Brushfoots, Sulphurs, Skippers, and Hairstreaks. Bird activity was excellent too, including three species of flycatcher: Great Crested, Eastern Phoebe, and Eastern Kingbird. Woodpeckers were also plentiful as I quickly tallied four species: Downy, Hairy, Red-bellied, and the large and very vocal Pileated.

Rose-breasted Grosbeaks, Brown Thrashers, and Gray Catbirds could all be seen and heard on the east side of Saunders Pond. An immature Red-tailed Hawk, perched adjacent to the pond, was continuously harassed by both Red-winged Blackbirds and a Baltimore Oriole. Turkey Vultures and an Osprey were among the other birds of prey present. As was the case last week, Killdeer and Spotted Sandpipers were both noticed around the pond. Multiple small songbird species were observed, with warblers, vireos, and various sparrow species recorded.
Field Sparrows were among the several sparrow species observed in London, Ontario this past week.
With plenty of sunshine and moderate winds predicted, this weekend looks perfect for birding. If I had to pick one area that is producing the best views and the most variety, it would definitely be Westminster Ponds ESA.
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.
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.
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.
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.
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.

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.
Yellow Warblers were among the 57 species of birds that I observed while birding in Point Pelee National Park.
This past week I packed up my camera and binoculars and headed to Point Pelee National Park in Leamington, Ontario for the 2015 Festival of Birds. Point Pelee National Park is located on an 8.5km peninsula of land extending into Lake Erie, and is the southernmost point of mainland Canada. Each spring thousands of birds stop over in the park to rest and feed after crossing the lake during their migration north. Deemed the warbler capital of Canada, Point Pelee National Park is a birder’s paradise. The mixed habitat within the park attracts more than just warblers, with 365 species reported to Ebird.
Eastern Kingbirds could be observed throughout the park in the vegetation emerging from the dunes.
I arrived at the park mid-morning and upon rolling my window down to pay the very modest $7.60 adult entrance fee, I could immediately hear the calls of both Yellow Warblers and Baltimore Orioles. Continuing into the park, the songs and calls of various birds filled the air. Red-winged Blackbirds, Warbling Vireos, and American Robins could all be seen and heard.
I observed 14 species of warbler, including this Palm Warbler, while birding in Point Pelee National Park, also known as the warbler capital of Canada, during the 2015 Festival of Birds.
My late arrival to the park meant that the parking areas closest to the visitor centre were full, so park staff directed me to the closest available parking located at Black Willow Beach. From there, it was a short 1.5 km walk to the visitor centre where a shuttle ride to the tip is available. Grabbing my camera, binoculars, a few snacks and some water, I headed south down the wooded path paralleling the lake toward the visitor centre.
The mixed habitat throughout Point Pelee National Park attracts a variety of birds. In one of the swampy wooded areas is where I located this Solitary Sandpiper.
Immediately, I was treated to excellent views of Baltimore Orioles, Yellow Warblers, and Eastern Kingbirds. In fact, you could hardly walk a few steps without encountering a Yellow Warbler or Baltimore Oriole. Hermit Thrushes and House Wrens could be seen flitting along near the ground. Scanning at eye level, more warblers came into view with Palm, Black-throated Blue, and Chestnut-sided all being recorded. Tree and Barn Swallows circled overhead as they followed the adjacent dune. I had a good feeling about the day as I had barely been in the park ten minutes and had already observed over a dozen species.
Black-throated Blue Warbler
After arriving at the visitor centre, I hopped on the shuttle and headed for the tip. A distance of only 2 kms, this stretch of park is very much walkable, but with so many trails yet to explore, I figured this was a good opportunity to rest my legs and rehydrate.
Chestnut-sided Warblers were abundant on the many trails within the park.
Getting off the shuttle at the tip exhibit area, I could see more Barn Swallows flying around the pavilion. A small crowd of birders had gathered to observe a Wilson’s Warbler as it moved about an Eastern Red Cedar tree. Scanning the tree with my binoculars, I quickly added this species to my daily total. My hike around the tip didn’t reveal as many species as I hoped, but I attributed this to my late arrival. From what I have heard, it is best to be at the tip at sunrise when birds that migrated the previous night are low down and in plain view as they recuperate from their long flight across Lake Erie. The tip was still rewarding as I added Red-breasted Mergansers, several gull species, and a Ruby-throated Hummingbird to my day’s list. While waiting for the shuttle to pick me up, I observed several of the previously observed Barn Swallows flying in and out of their nests underneath the pavilion at the tip exhibit; a promising sight given that these birds are a Species at Risk in Ontario. It was here too that I added an Orchard Oriole to my tally.

Heading back north toward the visitor centre, I got off the shuttle at the end of the Woodland Nature Trail. It was here where even more species were observed. More warblers including, Bay-breasted, Magnolia, and Blackburnian, as well as several vireos with Red-eyed, Blue-headed, Yellow-throated, and Philadelphia all being recorded in a short section of the forest. Several sections of this trail contained wooded, swampy, habitat, perfect for the endangered Prothonotary Warbler, but unfortunately I was unable to locate one despite other birders reporting them from this area. This same habitat is preferred by other species too, and did reveal a Veery and Solitary Sandpiper. Continuing my way along the trail to the visitor centre more of the same species were observed.
This rufous morph Eastern Screech-Owl was one of my favourite birds observed at this year’s Festival of Birds.
Next, I wanted to check out the Tilden Woods Trail where a rufous morph Eastern Screech-Owl had been reported daily for over a week. The owl was visible from the main trail in a tree cavity, but without the help of fellow birders, would have gone unnoticed by many, myself included. It was great to see so many birders helping each other out so that everyone could see this incredible species. Further along the Tilden Woods Trail, I added two more warbler species to my count: Black-throated Green, and Blackpoll.
This male Orchard Oriole was observed behind the tip exhibit while I waited for the shuttle.
After exiting Tilden Woods Trail, I made my way back to the path I started on and headed for my truck. Arriving back at my truck I decided to head down to the beach so I could have my lunch and tally up my day’s total. Glancing out over Lake Erie I could see a large thunderstorm moving in. Heavy rain, 100 kph winds, hail, and even a tornado warning were now forecast, so I was glad my day at the park was coming to an end. In total, I observed 57 species, with four of them being lifers. Totally satisfied with my day birding, I packed my gear into my truck and headed for home. I barely made it past the park entrance when it began to pour rain.
This Veery was one of several species of thrush located on the Woodland Nature Trail.
If you have never been to Point Pelee National Park for the Festival of Birds, I highly recommend it. Birders and non birders alike will be impressed by all of the birds and the park’s beauty. This was my first visit, as I have been scared off in previous years by the crowds that this festival draws. Take my advice, do not let the crowds scare you. Plan your trip for through the week to avoid the busiest days, and take part in this incredible experience. I am planning on making this an annual trip and will definitely spend spend more than one day at the park each spring in hopes of seeing even more of the 365 species that have been recorded there.
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.
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.
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.
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.
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.
Northern Cardinals are among the birds beginning to gather leaves and other nest materials. Leaving some behind when doing your yard cleanup will benefit your feathered friends.
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.
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.

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.
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.
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.
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?
Time is running out to observe overwintering species such as Snowy Owls in our area.
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.
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.
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.
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.
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.
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.
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.

A complete list of the waterfowl observed this past week on the Thames River is as follows:

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.
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.
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.
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.
I was able to photograph the Harlequin Duck in flight as he followed a flock of Common Goldeneyes downriver.
Since speaking with Wei Chen this past Monday on CBC’s Ontario Morning about the rare Harlequin Duck overwintering on the Thames River, I have received several emails from fellow birders looking for assistance in locating this bird. Let me start by saying that locating this bird is not as easy as many think. I have been fortunate to locate the male Harlequin Duck most days, but it has required quite a bit of leg work.
If you still need this bird for your life list and are hoping to find it at Springbank Park in London, Ontario I would like to offer a few suggestions based on my experiences. Begin your search at Storybook Gardens and walk the section of river between Springbank Dam and the old pump house. I personally have had the best luck locating the Harlequin Duck early to mid afternoon. Most days I chose the afternoon only because I wanted to wait for the temperatures to warm up, making walking more comfortable. On the few occasions I set out in the morning I was unsuccessful locating the Harlequin.
The fast moving water west of the pump house is a favourite spot of the male Harlequin Duck. There is a lot of tree cover on the bank and this duck is often tight to it. A methodical search in this area is often rewarding.
Be sure to look very close to the near bank as the Harlequin is quite comfortable close to shore in areas where there is thick tree cover. The section of Thames River between the parking lot at Storybook Gardens and the old pump house has a lot of tree cover on the near bank, so take your time and look as closely to the bank as you can. I have had a lot of success locating the Harlequin in the fast moving water west of the pump house, only a few feet from the bank. In open areas, the Harlequin Duck is more likely to find security mixed in with the other waterfowl on the far side of the river. It is here where scanning with binoculars can reveal its location. I personally have not seen the Harlequin Duck upstream from the pump house, so once you reach this point I recommend turning around and heading back downstream.
Further west towards the dam I have repeatedly located the Harlequin Duck in tight to shore, where the the lower road curves and carries on to the dam. If you are not familiar with this location, to the south there is a building up on the hill with washrooms and another parking lot directly behind that. The tree cover on the bank here is especially thick, but a favourite location of the Harlequin Duck. This is the most westerly location in which I have seen the Harlequin; I have yet to see it as far downstream as the dam.
On cloudy days the Harlequin Duck’s plumage camouflages well against the dark water. Here the male Harlequin slips past some Mallards and Canada Geese.
The Harlequin Duck has been associating with a small flock of Common Goldeneyes. Scanning these small flocks will often reveal the Harlequin. Pay attention to flying Goldeneyes too. The wing beats of the Common Goldeneye can be heard when taking off. Learn to recognize this sound and immediately look in the direction when you hear it. On several occasions I’ve observed the Harlequin Duck as the trailing bird in a group of Goldeneyes as they move up or down river.
Despite the Harlequin Duck’s colourful plumage, it appears quite dark from a distance. On cloudy days the dark, shadowed water provides excellent camouflage; looking for its white markings is critical. On sunny days, the slate blue feathers blend in with the bright blue water, making sightings challenging under these conditions as well. Again, the white markings on the head and back are what best gives away the Harlequin Duck’s location.

Locating the Harlequin Duck typically takes a fair bit of legwork. You may be one of the lucky ones who gets out of your car and there it is, but be prepared to spend a few hours searching. On days when more birders are searching for the Harlequin there are many people scanning the river and sharing their sightings, but the increase in foot traffic makes the Harlequin more wary. It is on these days I have found searching as close to shore as possible the most successful.
It looks like we are in for plenty of sunshine on Saturday, so I imagine Springbank Park will be quite busy again with birders hoping to add the endangered Harlequin Duck to their life lists. If you are one of them, keep these suggestions in mind while you search and I think your chances of success will be much greater.
The Common Goldeneye is one of the many species of diving duck that overwinters on the Thames River. In recent years, the number of these ducks on the river during winter months has increased.
Once again this winter, the Thames River is hosting a remarkable variety of waterfowl. With ice coverage on the Great Lakes exceeding 80%, ducks, geese, and grebes are migrating inland searching for open water. Several of these birds feed on a variety of aquatic life including: fish, molluscs, crustaceans, larvae, and even aquatic vegetation. For diving ducks and grebes, feeding takes place by diving below the surface and capturing prey with their bills. In order for these diving ducks to be successful, they must be able to reach the bottom to access snails, clams, and crayfish from beneath rocks and logs on the river bed.
Of the fifteen species of waterfowl currently overwintering on the Thames River, eight are deemed rare by eBird either by species or location. Redheads are one of the species deemed rare. Each winter we observe more Redheads on the river during winter months. Readheads are a diving duck that feed on aquatic vegetation.
The wide variety of waterfowl that have overwintered on the Thames River the past few years is a good indication of the improved overall health of the river. Since Springbank Dam became non-operational in 2008, the Thames River is slowly transforming back to its natural state. The most observable change is the natural reforestation occurring along the river banks. The increased vegetation in this riparian area is preventing bank erosion and reducing the number of harmful nutrients and pesticides that enter the river. Bank erosion leads to sedimentation which negatively impacts the health of the river bottom, where many of the tiny vertebrates and invertebrates that these ducks feed on live. High nutrient levels, such as phosphorus, create unhealthy algae blooms which again negatively impact the overall health of the river.
Each winter Hooded Mergansers can be observed on the Thames River in London, Ontario. These small diving ducks can be observed feeding on small fish and in this case crayfish.
When Springbank dam was operational, water was held back within the city from late May until early October each year. Damming the river promoted sedimentation, caused nutrients and bacteria to build up, and harmful algae to form. Too much algae is harmful as it reduces water quality and starves other organisms of oxygen. These factors are what led to the unsightly appearance and smell so many Londoners associated with the Thames.
Treated and untreated sewage continues to be released into the Thames River at various locations around the city, including Greenway Pollution Control Centre. Human and animal waste increases harmful bacteria levels, such as e-coli, which also negatively impacts water quality. Allowing the Thames River to flow freely, reduces the build-up of this bacteria within our city.
Another bird deemed rare for our location by eBird is the Greater Scaup. Once again this winter, scaup have been drawn to the open water of the Thames River, and the abundance of aquatic life that is paramount for them surviving the winter months.
By having a free-flowing river the past six years, levels of harmful bacteria, nutrients, sediment, and algae have all improved. These improvements are published in the Upper Thames River Conservation Authorities Watershed Report Cards. To some, these benefits are not visible by simply looking at the river. In fact, many Londoners believe the water level appears too low based on the Thames River’s previously unnatural dammed levels.
The improved water quality is evident by the increase and abundance of waterfowl overwintering on the Thames River each year. The improved water quality and reduction in sedimentation have created a much healthier river bottom. As a result, several small organisms that reside on the river bottom are thriving; ones that you and I can’t observe while walking along the river in one of our city parks. This abundant aquatic life is what keeps these many species of waterfowl present on the Thames River throughout the winter months. Without suitable water and adequate food supply, these ducks would continue their migration to the southern United States or the Atlantic coast.
This Harlequin Duck is listed as endangered in Canada. Maintaining and improving the health of the Thames River is something we need to take seriously in order for such species to survive. This rare Harlequin Duck is one of the many rare species currently overwintering on the Thames River.
Simply put, wildlife does not lie. The increase, abundance, and variety of all wildlife, not just waterfowl, present on the Thames River indicate a healthy and sustainable river. Water from the Thames River eventually reaches Lake Erie, where London draws a portion of its drinking water from. Keeping the river in its natural state will not only protect endangered species, like the Harlequin Duck, but it will also help protect the future of our drinking water. The natural reforestation that is occurring along the river banks improves the urban forest, and our air quality as well.
Perhaps we should take more time to observe the nature around us and use it to measure the health of our environment.
Over half of the eastern population of Harlequin Ducks overwinter off coastal Maine. Luckily for area birders, this male Harlequin Duck can be observed on the Thames River in 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.

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.
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.
Winter provides excellent opportunities to view a wide variety of waterfowl on the Thames River. Here a male Redhead is captured flying downstream.
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:

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.
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.
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.

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.
