The white-thighed swallow (Atticora tibialis) is a species of bird in the family Hirundinidae, the swallows and martins. It is found in Bolivia, Brazil, Colombia, Ecuador, French Guiana, Guyana, Panama, Peru, Suriname, and Venezuela.
The white-thighed swallow was described in 1853 by John Cassin as "Petrochelidon ? tibialis". Cassin was unsure that it belonged in that genus, stating that it "does not appear to us to belong to either of the genera of swallows heretofore established", which were Petrochelidon and Collocalia. (The latter genus is now applied to some swifts.) In the late 1800s it was assigned to genus Microchelidon and for much of the twentieth century and into the twenty-first it was assigned to the monotypic genus Neochelidon. Based in part on a study published in 2005, beginning in 2008 Neochelidon was merged into the present genus Atticora.
The white-thighed swallow and the black-capped swallow (A. pileata) are sister species and share genus Atticora with the white-banded swallow (A. fasciata). The white-thighed swallow has these three subspecies: Atticora tibialis minima (Chapman, 1924)

Possible
About 30% of wildlife watchers report a White-thighed Swallow sighting in Serra dos Órgãos National Park on a given day, based on 167 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 90th most-seen of the 336 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.
May and August–September
In those months about 40% of wildlife watchers report a White-thighed Swallow in Serra dos Órgãos National Park on a given day, against about 10% in March and December, the lowest months.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most White-thighed 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.
Yes
Of the 8 parks where we can rate White-thighed Swallow sightings, Serra dos Órgãos National Park has the highest daily chance: about 30%. Next come Sierra de la Macarena National Park (Colombia, about 10%) and Podocarpus National Park (Ecuador, under 5%).
Same family: Hirundinidae

GBIF citizen-science records
It is estimated from how often the White-thighed Swallow is recorded against all the birds logged in Serra dos Órgãos National Park (167 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.
