After the Equinox

Black-capped Chickadee

Black-capped Chickadee

While it is true that fall migration proceeds at a much more leisurely pace than migration in the spring, each species moves according to its own internal calendar. In late August and early September you might find warblers, Rose-breasted Grosbeaks, flycatchers, vireos, orioles, Cedar Waxwings, and Scarlet Tanagers foraging together in a single patch of woods. A month later the same patch of forest might hold sparrows, kinglets, Winter Wrens, Rusty Blackbirds, nuthatches, Hermit Thrushes, and boreal finches, while waterfowl on rivers and ponds increase in numbers and diversity. I usually notice the switch around the fall equinox, when the sparrows start to outnumber the warblers and I realize that it’s been a while since I last saw a flock of Cedar Waxwings. Now is the time to look for American Pipits in open scrubby areas or along rocky shorelines, scoters and grebes along the river, hawks and Turkey Vultures soaring toward southern climes, and any lingering warblers in the hope it is something other than a Yellow-rumped.

The Ontario Breeding Bird Atlas

Common Grackle (fledgling)

Common Grackle (fledgling)

This year marks the start of a five-year breeding bird survey for the third Ontario Breeding Bird Atlas, which is a collaboration between Birds Canada, the Canadian Wildlife Service, the Ministry of Natural Resources and Forestry, the Ontario Field Ornithologists, and Ontario Nature.  Approximately 300 bird species breed in our province, and the goal of the atlas is to map the distribution and relative abundance of these species by looking for evidence of breeding for as many species as possible. By conducting surveys every 20 years researchers are able to determine which species are expanding their range, which ones are shrinking, which species are increasing in abundance, and which ones are declining.  Although data collection began on January 1, 2021, breeding bird surveys don’t really kick into high gear until mid-May once almost all of our breeding birds are back from their wintering grounds in central and South America to Ontario.  As I was not a birder when data was being collected for the second atlas (2001-2006), this was my first chance to participate as a volunteer atlasser, and I jumped at the opportunity. Over the last few years, and especially during the lockdowns of the COVID-19 pandemic, I’ve gotten to know the birds within my own area quite well, and after looking at a list of the species found in my area during the second atlas, I knew I could contribute some new data on species that were missing. For instance, Red-shouldered Hawk wasn’t found in the last atlas in my area, although I found a pair occupying a nest in Stony Swamp back in 2016. Barn Swallow was recorded only as being in suitable habitat in the last atlas, while they used to nest under the bridge at the Eagleson ponds before the city put wire mesh underneath it. And Killdeer was last reported as showing agitated behaviour, while I’ve seen a fuzzy newly-fledged bird at the Eagleson ponds once.

Migration Highlights from September

Savannah Sparrow

Savannah Sparrow

I have truly enjoyed these past few months working from home. Without the daily two-hour commute, I have been getting out as often as I can before work and at lunch to take advantage of the quiet weekday trails close to my house. With the arrival of September, however, I’ve been less focused on insects and more interested in birds. Migration has started, though so quietly it is hard to tell when post-breeding dispersal ended and true southward movement of the birds began. I’d already seen some good birds in the last few days of August, such as a juvenile Red-shouldered Hawk at Sarsaparilla Trail, a Red-necked Phalarope at the Moodie Drive quarry, and a Cape May Warbler in my own backyard, but I was eager to get out and see large numbers of songbirds flitting through the trees in various migrant traps, and start creating eBird lists with 40 or 50 different species.

Counting Birds

Upland Sandpiper

Sometime in early 2020 I decided to put in the effort this year to see or hear 200 bird species in Ottawa this year, something I’ve failed to do since 2015 when I observed 210 species while working full-time. I also managed to observe 202 species in 2013 and 205 species in 2011. After 2015 my annual totals dropped to 182, 196, 166 and 177. This was probably about the time that I decided not to chase birds as much as I used to, as it’s not the most enjoyable aspect of birding for me. I prefer exploring new areas or old favourites, just to see what species breed or spend the summer there, or migrate through in the spring and fall. This meant I haven’t gone to see the Sandhill Cranes at Milton Road in the fall since 2015, the Snow Geese in the east end since 2015, or the grassland sparrow species (Vesper, Clay-colored and Grasshopper) at the airport since 2017. Sometimes I get lucky and find those species closer to home; individual Snow Geese are usually seen annually in the west end during spring and fall migration, while Clay-colored Sparrows were found at the Goulbourn sparrow field in 2017 before development ruined that area as a birding spot.

Snippets from Migration

Common Yellowthroat

Migration has been strange this year. Because of the lengthy cold spell at the beginning of May it seemed as if migration had stalled; for so long I felt as though I were waiting for it to begin, then things happened so quickly that now I wonder whether it has passed me by. The White-crowned Sparrows that usually show up in my backyard every year between May 3rd and 5th didn’t arrive until the 14th; the Common Terns that arrive at the Eagleson Ponds between May 10th and May 14th didn’t arrive until May 19th. Neither species stayed long, either. The terns were only there for one day before moving on, instead of spending two or three days. It is harder to know if the White-crowned Sparrow I saw over the course of a few days was the same one or a different one, as many have been singing in our area in the middle of the month.

The warblers came, and the warblers went. I’ve had several Black-throated Blue Warblers this year, and many repeat sightings of local breeding species – but of the ones that only pass through, I’ve sometimes only been lucky to get one: one Cape May Warbler, one Blackburnian Warbler, one Tennessee Warbler, one Bay-breasted Warbler. Again, is this a reflection of my spending time mainly in Kanata south, rather than heading for the migrant traps along the river? There have been excellent reports from the usual spots (Mud Lake, Andrew Haydon Park), but even as the city parks reopened on May 6th and the NCC parking lots reopened on May 22nd as a result of declining Covid-19 cases in the city, I’ve been reluctant to go to the normal spring hotspots to avoid the crowds that tend to gather there, both birding and non-birding alike. This has less to do with any fear of the coronavirus than my preference for quiet birding experiences, away from the loud chatter and narrow, crowded trails that both increase exponentially as the spring wears on and weather warms up.

Dragonflies at Mud Lake

White Admiral

By the end of June it seemed that summer had finally arrived and the weather had returned to normal: the temperature had reached a consistent near 30°C, the state of emergency caused by the unprecedented spring flood had ended on June 12th, water levels were returning to normal, and the sun had finally come out! I was hoping that this meant that the dragonflies were also emerging on schedule again, and decided to head to Mud Lake on the last Saturday of June. Mud Lake is a fantastic place to see dragonflies in mid-summer, as all the dragonfly families except for Cordulegastridae – the spiketails – can be found there. Among the damselfly families both the spreadwings and pond damsels are well-represented; the broad-winged damselflies, mainly Ebony Jewelwings, are seen there from time to time. I had high hopes for my visit.

The Sunny South March Highlands

Red Columbine

It rained almost all day on Saturday, June 15th, so my hopes of going out and finding butterflies and dragonflies were ruined. At least Sunday promised to be gorgeous, and although the ground was soaking wet when I got up, there wasn’t a cloud in the sky. I drove out to the South March Highlands, one of my favourite conservation areas in Ottawa, hoping to find some skippers and swallowtails, and hoping to find the Yellow-throated Vireo that has been dominating my eBird alerts these days – I still haven’t seen this bird in Ottawa.

Images from Migration

Mourning Cloak

It’s been a slow start to spring migration. Normally by mid-May returning birds are everywhere, and songbirds are busy feeding and singing in the smallest of parks and unlikeliest of yards. This year, however, with the cold weather and heavy rains it feels like we are still two weeks behind schedule – I saw my first warbler species of the season (a Pine Warbler) at Mud Lake on April 14th, my second (a Yellow-rumped) at Andrew Haydon Park on April 21st, and then my third warbler (a Black-and-White) at the Eagleson Ponds on May 4th. It doesn’t help that Ottawa’s most dynamic and productive migration hotspot, Mud Lake, is closed to the public due to the flooding along the river, but even so I would have thought I’d have seen more warblers by now. It’s been difficult to find new species to add to my year list, even visiting different trails and conservation areas with Mud Lake off limits. Here are a few photos and some of my interesting finds from the past week.

Last Day in Paradise

Hispaniolan Parakeet

Our last day had finally arrived, and as our flight wasn’t until 8:45 pm, I got up early and went out birding before breakfast. I started at the beach, then walked the eastern-most path along the edge of the resort. I wasn’t expecting anything out of the ordinary, and my only goal was to catch up with the cuckoo-like bird Doran and I had seen on our second day.

I didn’t see the cuckoo, but the Northern Parula was in the same tree where I’d seen it before. There was a second warbler in the same tree – brownish overall, with a necklace of dark streaks and a noticeable white wing patch. I thought it might be a Cape May Warbler, but wasn’t able to confirm it until I saw the photos showing the greenish rump and yellow patch behind the auriculars.

Birds of Early Fall

Winter Wren

By the end of September there is a change in the air. There are fewer warbler species and more sparrows and thrushes and kinglets as the temperature starts to fall and the nights grow longer than the days. On the last Saturday in September I started my day with a walk at the Eagleson ponds, where only a few Greater and Lesser Yellowlegs remained after the recent rains caused the water levels to rise. The Great Black-backed Gull, three heron species, and a single kingfisher were still present as well. About 150 Canada Geese were swimming throughout the ponds; these were new, as only one or two families had stayed the summer. The only Red-winged Blackbirds I saw were all in a single flock of about two dozen birds flying over, and while Song Sparrows were still numerous, the first Dark-eyed Junco had arrived. A single Ruby-crowned Kinglet, two Yellow-rumped Warblers, and two Blackpoll Warblers were signs that the season was changing.
