Quick Facts About the Pacific Wren

Pacific Wren General Description

The Pacific Wren is a small brown bird that rarely grows larger than 5 inches long, with a wingspan between 4.5 and 6.5 inches. Its short tail helps give it a round appearance, and it also has a thin bill. It’s brown overall, with a few darker spots on the wing and tail.

Pacific Wren Range, Habitat, Behavior, Diet & Nesting

Range

You will primarily find the Pacific Wren in the Western United States, especially in Northern California, Oregon, and Washington State. Its range also extends into Canada and up into Alaska.

Habitat

The Pacific Wren prefers old-growth evergreen forests, and it likes to build its nests near fallen trees with upturned roots. After breeding season, you will see them in more diverse habitats, including backyards and parks. These birds also tend to huddle up in nesting boxes to stay warm when temperatures drop.

Behavior

The Pacific Wren prefers to hop along the ground, looking for food in decaying logs and dead trees. Most bird watchers notice that they tend to resemble a mouse or mole more than a bird when they do this. It’s an energetic species that often bobs its head and body while standing still and rapidly beats its wings during flight.

Diet

The Pacific Wren mostly feeds on the insects that it finds in dead trees and decaying wood. It enjoys beetles, flies, caterpillars, termites, and spiders but will also eat berries if available.

Nesting

The male Pacific Wren will begin seeking a mate in early spring. Once successful, the pair will choose a nesting spot in any natural cavity close to the ground, including holes created by woodpeckers and decaying wood. The nest is made of moss, grass, weeds, animal hair, and feathers. The energetic male will build several nests and encourage the female to choose the one that she likes best.
