The Wilson's Warbler is classified as Least Concern. Does not qualify for a more at risk category. Widespread and abundant taxa are included in this category.

The Wilson's Warbler, Wilsonia pusilla, is a small New World warbler. It is primarily greenish above and yellow below, with rounded wings and a long, slim tail. The male has a black crown patch which is greatly reduced or missing entirely in the female. It breeds in across Canada and south through the western United States, and winters from Mexico south through much of Central America. It is a very rare vagrant to western Europe. More

A Wilson's Warbler ready to take a bath at El Polin Spring. Natural History: The Wilson's Warbler feeds primarily on insects, much like the Orange-crowned Warbler. It takes cover in the low canopy layers or forests or shrubs. It nests near water or wet areas on ground or slightly above ground where it breeds from late April to August. General Distribution: In the Presidio, this species can be found in coastal scrub areas, forested areas, and around ornamentals. More

The Wilson's Warbler has a significantly large range reaching up to about 7.9 million square kilometers. This bird is found throughout North America and also in Bahamas, Belize, Bermuda, Cayman Islands, Colombia, Costa Rica, Cuba, El Salvador, Guatemala, Honduras, Nicaragua, Panama, Puerto Rico, Saint Pierre and Miquelon, Turks and Caicos Islands.

When observing Wilson's Warblers in bushes and trees, they flick their wings and tails similar to kinglets. We sometimes see them catch flying insects in the air. More

Wilson's Warblers breed in wet, shrubby areas within forests. In Washington, they are most often found in small breaks in the forest that have dense, moist, shrubby cover, especially willow and alder thickets. These areas can be natural clearings, wetland edges, avalanche chutes, clear-cuts, or stream corridors. During migration and winter, they use similar habitats. More

Wilson's Warbler is a colorful, widespread, relatively well known warbler of riparian, meadow, and humid forest thickets. Its combined breeding, migration, and wintering ranges cover nearly the entire North American continent. It has become something of a flagship species for the conservation of neotropical migrants and is considered a priority in several conservation plans because of widespread population declines and threats to its habitat.

Wilson's Warbler is very rare in winter in California, but specimens of both pileolata and chryseola have been collected during this season (Dunn and Garrett 1997). MANAGEMENT STATUS: No special management status. HISTORICAL BREEDING DISTRIBUTION CURRENT BREEDING DISTRIBUTION ECOLOGY AVERAGE TERRITORY SIZE In oak-bay-laurel habitat in Marin County, Stewart (1973) found 24 territories averaging 0.57 ha (1.3 ac) and ranging between 0.2-1.3 ha (0.5-3.2 ac).

Wilson's Warbler - Wilsonia pusillaA small, very active warbler of thickets and woodland edges, Wilson's Warblers are often more readily identified by birders due to their habit of foraging quite low in forest vegetation. They can be found nearly anywhere in the continental United States during their spring migration, but are generally much more common in the West than in the East. They tend to have increasingly brilliant plumage the as you move westward in the continent. More

Wilson's Warblers usually forage within ten feet of the ground, darting after flying insects or hovering in mid-air to glean insects from leaves. They also sometimes feed on the ground, probing the leaf litter for prey. The tiny Wilson's Warbler is an energetic bird that often makes a circular motion with its tail or wags it up and down. This tame and curious bird will usually approach at the sound of birders' spishing. More
