Description

Olive above and yellow below. The male's head is hooded in slate-grey feathers with darker feathers on the breast and a broken white eyering and dark lores. The female and immatures also show a hood but it is paler and the throat is usually tinged with white or yellow.

The habitat of MacGillivray's Warbler can vary dramatically, but will consistently include riparian habitats consisting of brush and deciduous thickets that are dense and shaded.

The primary song consists of 6 to 8 syllables as represented by "churry churry churry churry cheery cheery."

Mourning Warbler and grey headed Orange-crowned Warblers.

This is generally a shy and elusive species that is often difficult to detect in the field, although the male is usually conspicuous due to his loud songs from tree branches or shrubs of its breeding grounds. The MacGillivray's Warbler prefers to forage and nest in brushy thickets and along streams that are located in areas of dense second growths in which it primarily moves along the forest floor by hopping.
The ecological role of the MacGillivray's Warbler within boreal forested regions is of particular interest. These areas are subject to extensive logging and mining interests and these birds benefit due to their preference for second growth and disturbed habitats.
