Rare
Under 5% of wildlife watchers report a Black-backed Grosbeak sighting in El Impenetrable National Park on a given day, based on 9 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 205th most-seen of the 219 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.

That is one of El Impenetrable National Park's wettest months, with about 120 mm of rain against 25 mm in July. December has too few records to rate.

GBIF citizen-science records
It is estimated from how often the Black-backed Grosbeak is recorded against all the birds logged in El Impenetrable 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.
