About These Birds

Pacific Gull

Pacific Gull, 58–66 cm, is Australia's largest gull, resident on southern and western coasts. Massive yellow and red bill capable of cracking mollusc shells by dropping them from height. White body, black mantle and wings. Omnivore; forages on rocky shores and beaches. Slow-maturing; takes 4 years for adult plumage.

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.
