Taxonomy and systematics

edit

Rothschild's swift, white-chested swift, (Cypseloides lemosi), American black swift (C. niger), and sooty swift (C. fumigatus) form a superspecies. Some authors have treated Rothschild's and sooty swifts as conspecific.[5] Rothschild's swift is monotypic.[2]

Description

edit

Rothschild's swift is about 15 cm (5.9 in) long. It has long, broad wings and a short squarish tail. Its plumage is a uniform medium brown.[6]

Distribution and habitat

edit

Rothschild's swift is found from Bolivia's Santa Cruz Department south into northwestern Argentina as far as Córdoba Province. There are no records in Peru despite its being included there in some taxonomic lists. The species' habitat requirements are not well known. Most records have been over evergreen montane forest at elevations between 500 and 2,000 m (1,600 and 6,600 ft).[6]

Behavior

edit

Migration

edit

Rothschild's swift appears to be a year-round resident in most of its range, though it might winter at the northern end of it.[6]

Feeding

edit

Like all swifts, Rothschild's is an aerial insectivore, but no details of its diet are known.[6]

Breeding

edit

Nothing is known about Rothschild's swift's breeding phenology.[6]

Vocalization

edit

As of late 2022, xeno-canto had a single recording of a Rothschild's swift vocalization, and the Cornell Lab of Ornithology's Macaulay Library had none. It reportedly makes a "short 'pip' or 'peep'" in flight.[6]

Status

edit

The IUCN has assessed Rothschild's swift as Near Threatened. It has a small range and an estimated population of 6000 to 15,000 mature individuals; the latter is believed to be stable. Much of the Yungas forest where it lives has been logged or converted to agriculture.[1] It does occur in some protected areas.[6]
