About These Birds
Mediterranean Gull
Mediterranean Gull, 36–38 cm, has expanded dramatically since the 1970s, breeding across Europe from the Black Sea to Britain. Pure white body, jet-black hood in breeding plumage — the only gull with entirely white wingtips. Piscivore and invertivore; nests in colonies, often with Black-headed Gulls.
River Tern
River Tern, 38–43 cm, is a large freshwater tern of South and Southeast Asia, found along major rivers from Pakistan to Thailand. Yellow-orange bill, grey back, black cap in breeding plumage. Piscivore; plunge-dives into clear river water. Near Threatened due to river sand-mining and disturbance.
