Swifts (Apodidae)

Chestnut-collared Swift (Cypseloides rutilus) - HBW 5, p. 419

French: Martinet à collier roux German: Rothalssegler Spanish: Vencejo Cuellirrojo

Taxonomy: Hirundo rutila Vieillot, 1817, Guyana.
Forms superspecies with C. phelpsi. It has recently been suggested that present species, probably along with less studied C. phelpsi, be included in Streptoprocne due to similarities in clutch size, development of young, and plumage, and these details would certainly suggest a close link with that genus; species formerly placed in Chaetura. Race brunnitorques rather similar to nominate, and may be synonymous. “Chaetura nubicola” is synonym of present species. Three subspecies currently recognized.
