The Bill of this Bird is white: The Breast and Belly white. All the rest of the Body dark grey; but in some places black, inclining to Lead-color. In Virginia and Carolina they appear only in Winter: and in Snow they appear most. In Summer none are seen. Whether they retire and breed in the North (which is most probable) or where they...

Possible
About 20% of wildlife watchers report a Dark-eyed Junco sighting in Białowieża National Park on a given day, based on 9 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 61st most-seen of the 182 birds we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
February
In that month about 80% of wildlife watchers report a Dark-eyed Junco in Białowieża National Park on a given day, against under 5% in April to January, the lowest months.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Dark-eyed Junco sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
25th of 41
Of the 41 parks where we can rate Dark-eyed Junco sightings, Białowieża National Park ranks 25th at about 20%. The best odds are in Yosemite National Park (United States, about 80%), Denali National Park (United States, about 80%) and Kluane National Park (Canada, about 80%). All parks ranked.
Same order: Passeriformes
The closest relatives of the Dark-eyed Junco that you can see in Białowieża National Park (order Passeriformes, Perching Birds) are Chaffinch (about 80%), Eurasian Blackbird (about 70%) and Great Tit (about 70%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Dark-eyed Junco is recorded against all the birds logged in Białowieża National Park (9 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.
