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 →

With luck
About 10% of wildlife watchers report an Andean Swallow sighting in La Paz on a given day, based on 33 verified sightings from GBIF citizen-science data. It is the 48th most-seen of the 88 birds we can rate there. Over three days the chance rises to about 30%, and over a week to about 50%, if each day is a fresh chance.
December to February
In those months about 20% of wildlife watchers report an Andean Swallow in La Paz on a given day, against under 5% in April–July, September and November, the lowest months. Those are among La Paz's wettest months, with about 120 mm of rain a month against 10 mm in June.
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.
Yes
Of the 2 cities where we can rate Andean Swallow sightings, La Paz has the highest daily chance: about 10%. Next come Arequipa (Peru, under 5%).
GBIF citizen-science records
It is estimated from how often the Andean Swallow is recorded against all the birds logged in La Paz (33 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.
