Pacific Wren

The Pacific wren (Troglodytes pacificus) is a very small North American bird and a member of the mainly New World wren family, Troglodytidae. It breeds along the Pacific coast from Alaska to California and inland as far as Wyoming and the Black Hills of South Dakota. It migrates through and winters across the western half of the United States and Canada.

The Pacific wren nests mostly in coniferous forests, especially those of spruce and fir, where it is often identified by its long and exuberant song. Although it is an insectivore, it can remain in moderately cold and even snowy climates by foraging for insects on substrates such as bark and fallen logs. For the most part insects and spiders are its food, but in winter large pupae are taken and some seeds.
