Field notes

  • Formerly treated as a subspecies of the North American Cliff Swallow (Petrochelidon pyrrhonota).
  • Constructs colonial mud nests that are typically gourd-shaped but usually lack the long entrance tunnels found in related species.
  • Highly adapted to human-altered landscapes, often nesting on bridges, eaves, and concrete buildings.
  • Feeds almost exclusively in flight, targeting swarms of small insects over open fields and water bodies.
  • Displays a distinct pale whitish or buffy forehead patch that provides a sharp contrast against its dark blue-black crown.
Habitat
Arid scrub, agricultural areas, and urban environments near water or nesting sites.
Range
Western Ecuador and Peru, primarily along the Pacific coast and lower Andean slopes.
