Mascarene Islands
The Mascarene martin or Mascarene swallow ("Phedina borbonica") is a passerine bird in the swallow family that breeds in Madagascar and in the Mascarene Islands. The nominate subspecies occurs on Mauritius and Réunion and has never been found away from the Mascarene Islands, but the smaller Madagascan subspecies, "P. b. madagascariensis", is migratory and has been recorded wintering in East Africa or wandering to other Indian Ocean islands.
