What is the marbled murrelet?
The marbled murrelet (Brachyramphus marmoratus) is a small seabird from the North Pacific. It is a member of the family Alcidae, which includes auklets, guillemots, murres and puffins. It nests in old-growth forests or on the ground at higher latitudes where trees cannot grow. Its population has declined since humans began logging its nest trees in the latter half of the 19th century. The decline of the marbled murrelet and its association with old-growth forests—at least in the southern part of its range—have made it a flagship species in the forest protection movement.
