Bewick's Wren

Scientific name: Thryomanes bewickii

Sixteen subspecies of Bewick’s Wren are reported, and the two subspecies occurring in eastern North America have both declined substantially, perhaps due to competition from House Wrens which destroy Bewick’s Wren’s eggs. One Bewick’s Wren in California reached the age of eight years in the wild.

Unlike Carolina Wrens which remain paired all year, Bewick’s Wren pairs separate for the winter. They are year-round residents in most areas, and so may encounter their mate during the winter, though pairing actually takes place in early spring.
