The Andean swallow (Orochelidon andecola) is a species of bird in the family Hirundinidae, the swallows and martins. It is found in Argentina, Bolivia, Chile, and Peru. The Andean swallow was originally described as Hirundo andecola. It was later assigned by different authors to genera Petrochelidon, Stelgidopteryx, and Haplochelidon. Following a study published in 2005 it was moved to the resurrected genus Orochelidon that had been erected in 1903.
The Andean swallow shares genus Oroichelidon with the pale-footed swallow (O. flavipes) and brown-bellied swallow (O. murina). The Andean swallow is 13.5 to 14 cm (5.3 to 5.5 in) long and weighs 14 to 19 g (0.49 to 0.67 oz). The sexes have the same plumage. Adults of the nominate subspecies have a mostly glossy greenish black head with black lores, gray ear coverts, and a gray-brown chin and throat. Their upperparts are mostly glossy greenish black with a brownish rump and uppertail coverts. Their tail is square or somewhat notched. Their breast and flanks are gray-brown and... Wikipedia →

Likely
About 60% of wildlife watchers report an Andean Swallow sighting in Lauca National Park on a given day, based on 641 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 10th most-seen of the 112 birds we can rate there. Over three days the chance rises to about 90%, and over a week to over 90%, if each day is a fresh chance.
July
In that month about 80% of wildlife watchers report an Andean Swallow in Lauca National Park on a given day, against about 40% in April, the lowest month. That is one of Lauca National Park's driest months, with about 5 mm of rain against 150 mm in January.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Andean Swallow sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Lauca National Park, in our data
Lauca National Park is the only park on Wallace's Line with enough records to rate Andean Swallow sightings: about 60% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Andean Swallow is recorded against all the birds logged in Lauca National Park (641 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.
