Guide to North American Birds
Priority Bird
Conservation status Total population is limited. Its rugged and remote range protects it from most direct human impacts, but climate change may be a serious threat: it often feeds near glaciers that come down to the sea, and those glaciers are receding. Would be vulnerable to spills and other pollution in coastal waters.
Family Auks, Murres, Puffins
Habitat Ocean, glacier waters; nests on barren slopes in coastal mountains. Found on cold sea waters, mostly in calm, protected bays and among islands. Usually fairly close to shore. Nests on islands and mainland, on steep barren mountainsides, talus slopes, rock slides, sometimes near glaciers.
A compact little seabird of Alaskan waters. Closely related to Marbled Murrelet and, like that species, rather mysterious and poorly known. Much more limited in range, being common mainly from Kodiak Island east to Glacier Bay. Solitary in its nesting; only a few nests have been found, so its breeding behavior is not well known.

Feeding Behavior

Forages while swimming underwater. Does most feeding in cold waters fairly close to shore, probably where relatively shallow.


Eggs

One. Pale olive with brown and gray spots. Incubation probably by both sexes, but details (including length of incubation period) unknown. Young: Probably fed at nest site by parent(s) for at least 2-3 weeks. Some young then may travel along streams and rivers to reach sea, probably before old enough to fly strongly; others may fly directly from nest to ocean.

Diet

Not well known. Has a shorter bill than that of Marbled Murrelet, suggesting a different diet; known to eat small crustaceans, and possibly eats fewer fish than Marbled Murrelet.


Nesting

Solitary in breeding, on islands and mainland; few details known. Nest site is on ground on steep rocky slope with little vegetation, often 1000-3000' above sea level and several miles inland from ocean (can be more than 45 miles inland). Often at base of large rock, and may be fairly near stream flowing toward ocean. No nest built, egg laid on bare rock or ground.

Migration

Mostly permanent resident, although must leave northernmost breeding areas in western Alaska in winter (when seas freeze solid). Extremely rare straggler south of southeastern Alaska.
