About These Birds
Yellow-legged Gull
Yellow-legged Gull, 52–68 cm, is the large gull of Mediterranean and Atlantic Iberian coasts. Yellow legs distinguish it from the pink-legged Herring Gull; darker grey mantle. Omnivore; highly adaptable — increasing in urban areas and landfills across southern Europe and North Africa.
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.
