About

The Pacific wren (Nannus pacificus) is a very small North American bird and a member of the mainly New World wren family Troglodytidae. The species was formerly lumped together with either the winter wren (Nannus hiemalis) of eastern North America alone, or also with the Eurasian wren (Nannus troglodytes) of Eurasia, then under the merged name of northern wren with the scientific name troglodytes having priority. Furthermore, although these three species were previously classified in the genus Troglodytes, they have been moved to the genus Nannus.
