Thick-billed Murre
Uria lomviaAlso known as Brünnich's Guillemot, Pallas' Murre
Thick-billed murres are heavy-bodied, pursuit-diving seabirds built for underwater propulsion rather than effortless flight. They nest in massive, noisy colonies on sheer ocean cliffs, laying a single pear-shaped egg directly on bare rock ledges without a nest. Before fledging, chicks jump off high cliffs into the sea guided by their fathers, who swim with them far out into pelagic waters.

- Why interaction risk is low
- Safe to observe at a normal distance.
- What to notice
- Recognize by its dark head, heavy bill with a distinct white gape stripe, and bright white underparts.
- Support conservation
- Observe from a respectful distance or from offshore boats, avoiding loud noises, drones, or sudden approaches near active nesting cliffs.
Responsible observation
- Cliff Viewing: Use binoculars or a spotting scope from established trails above colonies to avoid disturbing nesting pairs.
- Boat Observation: Keep watercraft at low speeds when traveling near rafted birds in coastal bays.
- Season Timing: Visit subarctic breeding cliffs between May and July to see dense breeding aggregations.
