What is the habitat of a murrelet?

Lo and behold, the nesting habitat of marbled murrelets was finally discovered––coastal old growth coniferous forests of the Pacific Northwest. With the discovery of a murrelet nest in a tree, a major evolutionary leap in seabird biology was revealed. Most animals stick to a life style similar to other closely related species.

Where do murrelets live in Washington State?

Logging poses a significant threat to the species’ survival, both because of the birds’ reliance on old-growth trees and because forests become fragmented, exposing the birds to greater risk of predation. Because they forage near shore, many Marbled Murrelets have died as a result of oil spills and other marine contamination.
