Pacific Wren Nests (formerly Winter Wren)

Like their unreasonably large and beautiful song, the Pacific wren (Troglodytes pacificus)  has a surprisingly elaborate nest. Abundant in forested landscapes around much of the Pacific Northwest, the Pacific wren typically constructs its nest out of mosses and builds it into an existing structure such as a rootwad of a fallen tree or the hanging moss on the underside of a tree branch or leaning trunk. Nests are spherical with a small entrance on the side giving access to an enclosed chamber where eggs are laid. Occasionally nest are constructed in tree branches and appear as a spherical glob of moss. My bird nest mentor, Emily Gibson, who first introduced me to Pacific wren nests, noted that the entrance to their nests, in western Washington at least, typically are lined with tiny conifer twigs.
