Black-legged Kittiwake

Rissa tridactyla

Also known as Kittiwake, Atlantic Kittiwake, Pacific Kittiwake

Black-legged kittiwakes are cliff-dwelling oceanic gulls named for their distinctive ringing vocalizations that reverberate across Arctic and subarctic breeding colonies. Unlike most gulls that forage on foot along shores, these agile seabirds spend winters in the open ocean and plunge-dive or surface-dip for small schooling fish. High cliff ledges provide safe nesting sites where mated pairs build sturdy mud and vegetation platforms to raise their young.

Very high

Why interaction risk is low: Safe to observe at a normal distance.
What to notice: Look for a solid yellow bill, black wingtips lacking white spots, and jet-black legs.
Support conservation: Keep a safe distance from cliff edges to prevent disturbance that might panic nesting adults into knocking eggs or chicks from ledges.

Responsible observation

Observation: Use binoculars or a spotting scope to view cliff-nesting colonies from a safe distance without disturbing birds.
Vocalizations: Listen for their loud, echoing 'kittee-wa-aaake' calls around coastal breeding sites.
