Rare
Under 5% of wildlife watchers report a Black-billed Seed-Finch sighting in Manu National Park on a given day, based on 18 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 538th most-seen of the 641 birds we can rate there. Over three days the chance rises to under 5%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Black-billed Seed-Finch in Manu National Park on a given day, so our monthly data shows no clear season.
Between 2 and 5 pm
Across all the parks we cover, that three-hour window holds the most Black-billed Seed-Finch sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Manu National Park, in our data
Manu National Park is the only park on Wallace's Line with enough records to rate Black-billed Seed-Finch sightings: under 5% of wildlife watchers there report one on a given day.

GBIF citizen-science records
It is estimated from how often the Black-billed Seed-Finch is recorded against all the birds logged in Manu National Park (18 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.
