Blue-and-white Swallow Pygochelidon cyanoleuca

  • Order: Passeriformes
  • Family: Hirundinidae
  • Polytypic: 3 subspecies
  • Authors: Ashley A. Dayer


Conservation Status

According to the IUCN Red List (BirdLife International 2009), the Blue-and-white Swallow is evaluated as a species of "Least Concern." It has an extremely large range with a population size that is already is large and apparently is increasing.

Effects of human activity on populations

The Blue-and-white Swallow likely is benefiting from the spread of human population and the clearing of tropical areas (Turner and Rose 1989). Local declines have occurred, such as following the extermination of vizcachas in an area, which limits the burrows available for swallow nesting (Turner and Rose 1989).
