Length: 5 in. (12 cm )
This very active warbler is most often found in low but thick bushes, especially willow and alder riparian areas. Its bulky nest is cup-like, and made of dead leaves, grass and moss. At high altitudes the nest is placed on the ground, and along the coast it is placed low in a shrub. Insects make up most of the diet, but in the fall and winter, some berries are also eaten.

The four-digit banding code is WIWA.
