The buff-bellied hermit (Phaethornis subochraceus) is a species of bird in the family Trochilidae, the hummingbirds. It is found in Bolivia and Brazil. The buff-bellied hermit is closely related to the sooty-capped hermit (P. augusti) and planalto hermit (P. pretrei). It is monotypic.
The buff-bellied hermit is 11 to 12 cm (4.3 to 4.7 in) long and weighs 3.5 to 4 g (0.12 to 0.14 oz). It has metallic green upperparts and ochre to buff underparts. The innermost pair of tail feathers are longer than the others and all have white tips.
The buff-bellied hermit is found in the eastern Andean foothills of Bolivia from southern Beni to eastern Santa Cruz departments and into the Brazilian states of Mato Grosso and Mato Grosso do Sul. It has also been recorded as a vagrant in Paraguay. It inhabits the understory of several landscapes including deciduous and semi-deciduous forest, secondary forest, open woodland, and shrubland. In elevation it ranges from 150 to 800 m (490 to 2,600 ft).

Rare
Under 5% of wildlife watchers report a Buff-bellied Hermit sighting in Parque Estadual Encontro das Águas on a given day, based on 73 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 184th most-seen of the 308 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 August
In those months about 10% of wildlife watchers report a Buff-bellied Hermit in Parque Estadual Encontro das Águas on a given day, against under 5% in May, July and September–December, the lowest months. Those are among Parque Estadual Encontro das Águas's driest months, with about 15 mm of rain a month against 190 mm in January. January to April have too few records to rate.

GBIF citizen-science records
It is estimated from how often the Buff-bellied Hermit is recorded against all the birds logged in Parque Estadual Encontro das Águas (73 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.
