General

MacGillivray's Warbler: Medium-sized warbler with olive-green upperparts and yellow underparts. White eye-ring is broken and slate gray hood extends to upper breast where it darkens to black. Female is similar but paler. Winter adult has paler hood and less distinct eye-ring.

Range and Habitat

MacGillivray's Warbler: Breeds from southern Alaska and the Yukon south to California and east to central New Mexico. Spends winters in the tropics from central Mexico south. Preferred habitats include coniferous forest edges, burns, brushy cuts, or second-growth alder thickets and streamside growth.

Breeding and Nesting

MacGillivray's Warbler: Three to six brown marked, white to creamy white eggs are laid in a grassy cup nest built close to the ground in a bush or tall weeds. Eggs are incubated for 11 days by the female.

Foraging and Feeding

MacGillivray's Warbler: Eats mostly insects; forages close to the ground in dense thickets.

Vocalization

MacGillivray's Warbler: Song is a rolling "swee-eet, swee-eet, swee-eet, peachy, peachy, peachy" that ascends four notes and then drops for the last two.

Similar Species
