Pygochelidon is a genus of birds in the swallow family Hirundinidae that occur in the Neotropics.
Taxonomy
[edit]The genus Pygochelidon was introduced in 1865 by the American naturalist Spencer Fullerton Baird with the blue-and-white swallow as the type species.[1] The name combines the Ancient Greek pugē meaning "rump" with khelidōn meaning "swallow".[2]
This genus was formerly treated as a junior synonym of the genus Notiochelidon.[3] It was resurrected to contain a clade of two species based on a genetic study published in 2005.[4][5]
Species
[edit]The genus contains the following two species:[5]
| Image | Common name | Scientific name | Distribution |
|---|---|---|---|
 | Blue-and-white swallow | Pygochelidon cyanoleuca | Breeds from Nicaragua south throughout South America, except in the deserts and the Amazon Basin; southern race migratory, wintering as far north as Trinidad. |
 | Black-collared swallow | Pygochelidon melanoleuca | Argentina, Bolivia, Brazil, Colombia, French Guiana, Guyana, Suriname, Venezuela, and possibly Paraguay. |
