The boreal chickadee (Poecile hudsonicus) is a small passerine songbird in the tit family Paridae.

Possible
About 30% of wildlife watchers report a Boreal Chickadee sighting in Banff National Park on a given day, based on 1,265 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 15th most-seen of the 191 birds we can rate there. Over three days the chance rises to about 70%, and over a week to about 90%, if each day is a fresh chance.
February
In that month about 60% of wildlife watchers report a Boreal Chickadee in Banff National Park on a given day, against about 30% in May–July and October, the lowest months.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Boreal Chickadee sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
5th of 14
Of the 14 parks where we can rate Boreal Chickadee sightings, Banff National Park ranks 5th at about 30%. The best odds are in Denali National Park (United States, about 50%), Wrangell-St. Elias National Park (United States, about 50%) and Kluane National Park (Canada, about 50%). All parks ranked.
Same genus: Poecile
The closest relatives of the Boreal Chickadee that you can see in Banff National Park (genus Poecile, Chickadees and Allies) are Mountain Chickadee (about 60%) and Black-capped Chickadee (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Boreal Chickadee is recorded against all the birds logged in Banff National Park (1,265 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
