Thick-billed Murre - Uria lomviaThe Thick-billed Murre is a large Auk found along both the Atlantic and Pacific Coasts of North America.  They are cold-water birds, breeding in northern Canada and Alaska, and only found near the lower 48 states during the winter months.  They are very similar to the Common Murre, and are often found nesting in the same locations.  They can be distinguished from Common Murres by their stockier appearance, thicker neck, and shorter and stouter bill.

Habitat: Found on rocky islands or shorelines, using areas with steep rocky cliffs and ledges for nest sites.  Outside of breeding, they are found in cold waters, often very far from shore.

Diet: Feeds mostly on fish, but will also eat crustaceans, squid, and marine worms.

Behavior: Forages by diving and swimming underwater after prey.  They can dive to depths of up to 200 feet.

Nesting: The Thick-billed Murre doesn't build a nest.  The female lays a single egg directly on the ground, usually on a rocky ledge of a cliff face.  Both the male and female help to incubate the egg, and both parents help to feed and raise the nestling after it hatches.

Song: On breeding grounds, has a groaning, startling aaarrrrrrrr call.  Usually silent away from breeding colonies.

Migration: Birds can be found as far north as open water exists during the winter, although some birds do move southward.  There is more movement southward for the winter in Atlantic populations than in Pacific populations.
