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.


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.


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.


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.


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.

Final Thoughts

The Pacific Wren is the smallest of the American Wrens, and you can find it in the extreme northwestern part of the United States and in parts of Alaska. It’s easy to find in the mornings during the mating season because it frequently sings while hopping along the ground, looking for insects. Its quick, steady movements resemble the actions of a mouse or mole, so it can be hard to see at first.
