White-winged Swallow

Overview

The white-winged swallow (Tachycineta albiventer) is a resident breeding swallow native to tropical South America. It is a largely non-migratory species, though populations in the southern parts of its range, such as Brazil and Argentina, migrate seasonally.

Identification

• Length of 14 cm with iridescent blue-green upperparts, contrasting white underparts and rump.
• Black wings featuring white edgings on the secondary flight feathers, along with a black bill and legs.
• Vocalisations include a harsh chirrup or a repeated, rising, buzz-like 'zweeed'.

Habitat

Found in lowland areas near bodies of water such as rivers and lakes, typically at elevations of about 500 m. Its range covers parts of South America east of the Andes, including Brazil, Colombia, Venezuela, and Argentina, but it is usually absent from the Pacific coast.

Diet

Feeds primarily in flight at low altitudes by catching flying insects, usually foraging over water but occasionally over land. Between foraging attempts, the bird perches on branches near water bodies.

Did you know?

The genus name Tachycineta is derived from the Ancient Greek word for 'moving quickly', reflecting the bird's flight characteristics.
