Rare
Under 5% of wildlife watchers report a Black-backed Woodpecker sighting in Glacier National Park on a given day, based on 151 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 99th most-seen of the 174 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
June and September
In those months about 10% of wildlife watchers report a Black-backed Woodpecker in Glacier National Park on a given day, against under 5% in July–August and October–May, the lowest months.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Black-backed Woodpecker sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
2nd of 14
Of the 14 parks where we can rate Black-backed Woodpecker sightings, Glacier National Park ranks 2nd at under 5%. The best odds are in Yosemite National Park (United States, about 10%).
GBIF citizen-science records
It is estimated from how often the Black-backed Woodpecker is recorded against all the birds logged in Glacier National Park (151 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.
