Field notes

  • It was historically classified as a subspecies of the White-winged Swallow but is now recognized as a distinct species based on plumage and range.
  • A key field mark is its white supraloral stripe which meets at the forehead, creating a 'white-faced' appearance compared to similar swallows.
  • The species is restricted to a narrow geographical band approximately 1,000 kilometers long between the Andes and the Pacific coast.
  • Unlike many congeners, it is frequently found in very arid environments, including coastal deserts and dry scrublands.
  • It is a cavity nester that utilizes holes in trees, vertical dirt banks, and occasionally man-made structures for breeding.
Habitat
Arid coastal scrub, agricultural fields, mangroves, and open areas near water sources.
