About These Birds

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.
African Skimmer
African Skimmer: 36–42 cm, black-and-white skimmer with a long bright orange-yellow bill where the lower mandible is longer than the upper. Flies low over large rivers and lakes, cutting the water surface with the lower bill to catch fish. Resident and partial migrant along large rivers and lakes of sub-Saharan Africa. NT.
