The white-eared puffbird (Nystalus chacuru) is a species of bird in the Bucconidae family, the puffbirds. It is found in Argentina, Bolivia, Brazil, Paraguay and Peru, where it inhabits tropical and subtropical dry forests, subtropical and tropical moist forests, gallery forests, tropical savanna, and heavily degraded former forest.
Like some other puffbirds, the white-eared puffbird is a round, plump bird with a very narrow tail. The head is relatively large, with a dark brown barred crown, and an orange, black-tipped bill. The sit-and-wait feeding strategy, for insects or opportunistic prey, may explain this body shape.
The bird has a medium-brown back and wings, with dark rufous speckles and bars; white and black flecked on the breast. The upper breast is white, extending to a narrow-to-medium white collar around the neck. There is a distinctive, medium-sized white ear patch, which gives the species its common name, and that is surrounded by a dark ear patch. It has a medium-sized tail in dark brown and slightly graduated, with narrow, widely spaced buffy bars, and a pale tip. It measures about 21–22 cm (8.3–8.7 in) in length and weighs between 48–64 g.

Possible
About 30% of wildlife watchers report a White-eared Puffbird sighting in Serra da Canastra National Park on a given day, based on 188 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 59th most-seen of the 294 birds we can rate there. Over three days the chance rises to about 60%, and over a week to about 90%, if each day is a fresh chance.
April and May
In those months about 40% of wildlife watchers report a White-eared Puffbird in Serra da Canastra National Park on a given day, against about 20% in January–March and July, the lowest months. Those are among Serra da Canastra National Park's driest months, with about 55 mm of rain a month against 280 mm in January.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most White-eared Puffbird sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.

Of the 8 parks where we can rate White-eared Puffbird sightings, Serra da Canastra National Park ranks 2nd at about 30%. The best odds are in Emas National Park (Brazil, about 50%).
GBIF citizen-science records
It is estimated from how often the White-eared Puffbird is recorded against all the birds logged in Serra da Canastra National Park (188 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.
