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 →

Possible
About 30% of wildlife watchers report a Brown-bellied Swallow sighting in Quito on a given day, based on 547 verified sightings from GBIF citizen-science data. It is the 21st most-seen of the 167 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.
January–February and April–May
In those months about 40% of wildlife watchers report a Brown-bellied Swallow in Quito on a given day, against about 20% in September to November, the lowest months. Those are among Quito's wettest months, with about 150 mm of rain a month against 25 mm in August.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Brown-bellied Swallow sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
2nd of 2
Of the 2 cities where we can rate Brown-bellied Swallow sightings, Quito ranks 2nd at about 30%. The best odds are in Bogota (Colombia, about 60%).
GBIF citizen-science records
It is estimated from how often the Brown-bellied Swallow is recorded against all the birds logged in Quito (547 verified sightings), 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.
