Where is this species commonly found?
Wilson’s Warbler is a common visitor of willow thickets. This little bird breeds in shrub thickets of riparian habitats, edges of beaver ponds, lakes, and bogs. It is a ground nester and builds a bowl of vegetation, lined with grass or hair. Nests are usually found at the base of shrubs, under bunches of grass, or placed low in shrubs. Its all-insect diet makes the Wilson’s Warbler one of the top insect-eating birds in Oregon.
A group of Wilson’s are called a “bouquet”, “Confusion”, “fall”, or a “wretch” of warblers.
