The plain swift is a medium-sized swift. Although this bird is superficially similar to a barn swallow or house martin, it is not related to those passerine species. The resemblances between the groups are due to convergent evolution reflecting similar life styles.
Region
Macaronesia (Canary Islands and Madeira)
Typical Environment
This species breeds on the Canary Islands (Spain) and Madeira (Portugal), using sea cliffs, rocky ravines, lava fields, and human structures for nesting. It routinely forages over both land and open sea, riding trade winds and updrafts along coastal escarpments. Birds are widespread from arid eastern islands to more humid, forested slopes, including laurel forest edges and cultivated valleys. It is largely sedentary, with local movements following weather and insect availability.

The plain swift is a uniformly dark, fast-flying swift endemic to Macaronesia, spending most of its life on the wing. Although it resembles swallows and martins, it is unrelated to those passerines—its similarities arise from convergent evolution to an aerial lifestyle. It breeds in crevices on cliffs and buildings and often forages far out over the ocean. Pairs are typically long-term and colonies can be noisy with their piercing calls.
Temperament
social and highly aerial
Flight Pattern
fast, scything flight with rapid wingbeats and long glides
Social Behavior
Nests colonially or in loose groups in crevices on cliffs and buildings. Pairs are typically monogamous and may reuse nest sites across years. Non-breeding birds form flocks that wheel high over coasts and valleys, often mixing with other swifts.
Migratory Pattern
Resident
Song Description
Calls are sharp, high-pitched screams and trills, often given in chattering groups around colonies. Vocalizations carry over long distances and intensify during display flights near nesting sites.
