Likely
About 50% of wildlife watchers report a Boreal Chickadee sighting in Wrangell-St. Elias National Park on a given day, based on 147 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 6th most-seen of the 93 birds we can rate there. Over three days the chance rises to about 90%, and over a week to over 90%, if each day is a fresh chance.
March and April
In those months about 70% of wildlife watchers report a Boreal Chickadee in Wrangell-St. Elias National Park on a given day, against about 30% in June, the lowest month. Those are among Wrangell-St. Elias National Park's driest months, with about 35 mm of rain a month against 130 mm in August. October to January have too few records to rate.
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.
Among the best
Of the 14 parks where we can rate Boreal Chickadee sightings, Wrangell-St. Elias National Park ranks 2nd at about 50%, level with the leaders once rounded. The best odds are in Denali National Park (United States, about 50%). All parks ranked.
GBIF citizen-science records
It is estimated from how often the Boreal Chickadee is recorded against all the birds logged in Wrangell-St. Elias National Park (147 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.
