The brown-bellied swallow (Orochelidon murina) is a species of bird in the family Hirundinidae, the swallows and martins. It is found in Bolivia, Colombia, Ecuador, Peru, and Venezuela. The brown-bellied swallow was originally described as Petrochilidon murina. Since then it had been placed in both Notiochelidon and Atticora. Following a study published in 2005 it was moved to the resurrected genus Orochelidon that had been erected in 1903.
The brown-bellied swallow shares genus Oroichelidon with the pale-footed swallow (O. flavipes) and Andean swallow (O. andecola). The brown-bellied swallow is about 14 cm (5.5 in) long and weighs about 12.5 g (0.44 oz). The sexes have similar plumage though females are duller overall than males. Adult males of the nominate subspecies have a mostly blackish head and neck with a blue-green gloss and a sooty gray-brown throat. Their upperparts are blackish with a blue-green gloss. Their tail is moderately forked; it and their wings are dark brown... Wikipedia →

GBIF citizen-science records
It is estimated from how often the Brown-bellied Swallow is recorded against all the birds logged in Los Nevados National Natural Park (3,541 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.
