Account for Marbled Murrelet (Brachyramphus marmoratus)

Unique in its family for its nesting habits,
this small alcid builds its nest in trees or more rarely on
the ground in coastal forests from the Aleutians and the southern
coast of Alaska south to northern California and from eastern
Siberia south to Japan. The first nest of this species was
not discovered until 1961 in Asia and 1974 in North America.
The bird flies at high speeds, sometimes allowing the air
to rush through its feathers, producing a jet-plane-like sound.
Since it nests solitarily, unlike many other members of its
family, and since it feeds at sea and visits its nests only
during periods of low light, finding and studying breeding
birds is a challenge.
During the winter this wary species is
found along the coast from the Aleutians to Monterey Bay,
California. The populations and distribution of the murrelet
have declined due to logging and coastal development, which
have destroyed much of its nesting territory; gill-net fishing
and pollution from oil spills also threaten the bird directly
and through threatening its prey. Estimate are that the populations
may have declined by as much as 40%; the bird is rare or uncommon
on the coasts of Washington to California, where it was common
or abundant in the early 20th Century. Populations have also
declined severely in the northern Gulf of Alaska, though Alaska
remains the stronghold of the species, with up to 90% of the
total North American numbers found there. The species is listed
as Threatened under the Endangered Species Act.
Conservation of the coastal forests where
it breeds is the most essential step to protect the species,
but limiting of gill-net fishing and containment of oil spills
are both important for its continued survival.
