About These Birds
Common Gull
Common Gull, 40–46 cm, is a medium-sized gull breeding across boreal Europe and Asia, wintering on Atlantic and Pacific coasts. Smaller and more dove-like than Herring Gull; yellow-green bill without red spot. Omnivore; follows ploughs, forages on shorelines and playing fields. Partially migratory.
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.
