Rare
Under 5% of wildlife watchers report a Chestnut-capped Puffbird sighting in Yasuní National Park on a given day, based on 88 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 313th most-seen of the 533 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.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Chestnut-capped Puffbird in Yasuní National Park on a given day, so our monthly data shows no clear season.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Chestnut-capped Puffbird sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
3rd of 5
Of the 5 parks where we can rate Chestnut-capped Puffbird sightings, Yasuní National Park ranks 3rd at under 5%. The best odds are in Manu National Park (Peru, about 10%) and Tambopata National Reserve (Peru, under 5%).
GBIF citizen-science records
It is estimated from how often the Chestnut-capped Puffbird is recorded against all the birds logged in Yasuní National Park (88 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.
