Brachyramphus marmoratus (Marbled Murrelet)

Synonyms: Brachyrampus marmoratus

Wikipedia Abstract

The marbled murrelet (Brachyramphus marmoratus) is a small seabird from the North Pacific. It is a member of the auk family. It nests in old-growth forests or on the ground at higher latitudes where trees cannot grow. Its habit of nesting in trees was suspected but not documented until a tree-climber found a chick in 1974, making it one of the last North American bird species to have its nest described. The marbled murrelet has declined in number 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 preservation movement. In Canada (north of 50° North Latitude) and Alaska, the declines are not
