About These Birds
Ross's Gull
Ross's Gull, 29–32 cm, is a delicate Arctic gull breeding in Siberian tundra, with its winter range largely unknown — possibly far out in the pack ice. Rosy flush to underparts in breeding plumage; wedge-shaped tail; black neck ring. Feeds on invertebrates and small fish along ice edges.
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.
