Canada Warbler

Wilsonia canadensis

While not a particularly shy bird, the Canada Warbler can be difficult to spot given its preference for dense undergrowth and brushy thickets.  They are often seen in pairs (possibly breeding pairs) during migration through the state. Canada Warblers are one of many species which will respond and approach to a birder's "pishing" sound.

Habitat: Prefers thick undergrowth of mature forests, especially near water or wetlands, on its breeding grounds.  Found in forests and thickets during migration through the state.

Diet: Primarily insects and spiders.

Behavior: Moves actively through foliage, gleaning insects from foliage and branches, and also flitting out to capture insects in mid-air as they are flushed by the warbler's movements.  They will also forage on the ground.

Breeding: Non-breeder in South Dakota

Song: Fast jumble of notes. 

Migration: Summers in central and eastern Canada, the Great Lakes region, the Northeastern U.S., and at higher elevations in the Appalachians.  Winters in South America.

Similar Species: Magnolia Warbler, Northern Parula

Conservation Status: Possibly in decline due to habitat loss, especially on South American wintering grounds. A somewhat common host to Cowbird paratism.
