Following a lengthy absence from my blog, caused primarily by an increased workload at school, I am finally able to post an update on the stunning fall we have had here in the mountains. Not only did we find Alberta’s second (maybe third) Prothonotary Warbler ever on Policeman’s Creek, but numbers of warblers were through the roof across the board, and several other exiting visitors dropped in for a visit.
It all started in late August, when my then near-daily walks along Policeman’s Creek began turning up unheard of numbers or strange species for the location. By the first of September, I’d found three falcon species, a Magnolia Warbler, 3+ MacGillivary’s Warblers, Evening Grosbeaks and, spectacularly, a lifer Canada Warbler!
Even with these (and other) exiting spots in August, there’s no doubt that September was the best month of the fall. Species that once would have been the best finds of the month were going unremarked – record numbers of Blackpoll Warblers, Fox Sparrows, Grey Catbirds and Nashville Warblers showed up, only to be ignored in favour of the simply stunning Prothonotary Warbler. 15 Swamp Sparrows came and went, and previously unreported Palm Warblers became the staple of anybody’s stroll down the creek.
To add perspective to these statements, I’ve added some tables showing the reports of a particular bird species in 2018 compared to all the reports of this bird before 2018. Both numbers represent birds reported in Canmore only.
A pretty staggering comparison, but it’s not just Palm Warblers. Blackpoll Warblers and Nashville Warblers saw a massive increase this year as well.

These remarkable changes were seen in many other species as well, but numbers were not the most interesting thing this year. As I mentioned above, we had a Prothonotary Warbler on the creek, and several other quite rare birds as well. Highlights included an out of place, out of habitat Lapland Longspur, a Pectoral Sandpiper probing the mud, and another lifer – immature Golden-crowned Sparrow!
Cedar Waxwings flitted about, and dozens of late Swainson’s and Hermit Thrushes flooded through the valley. Red-eyed Vireos made a few appearances, a Say’s Pheobe popped by one day, and I saw all three accipiters, Merlin, Kestrel and Prairie and Peregrine Falcons.
This young Cedar Waxwing caught my eye, and eventually made it into my 2018 North American Birds Calendar. Maybe not such a huge haul in one of Calgary’s Warbler hotspots, but a ridiculous wealth of birds for Canmore. I will almost certainly be able to post more as spring migrants pour in after a long, slow winter, so subscribe if you aren’t already to get all of my latest posts! Thanks for reading!
