About These Birds
Aleutian Tern
Aleutian Tern, 32–34 cm, breeds colonially in Alaska and Russian Far East, wintering in Southeast Asian waters — one of the most poorly tracked migrations among seabirds. Dark grey above, white below, black cap with white forehead. Piscivore; dives for small fish. Near Threatened.
Indian Skimmer
Indian Skimmer: 38–43 cm, black-and-white skimmer with an orange-and-yellow bill and white collar. Resident on large sandy rivers of the Indian subcontinent. VU. Feeds by skimming river surface with protruding lower mandible to catch fish. Severely threatened by sand-mining, dam building, and human disturbance at nesting colonies.
