MacGillivray’s Warbler

MacGillivray’s warbler (Geothlypis tolmiei) is a species of New World warbler. These birds are sluggish and heavy warblers, preferring to spend most of their time on, or near the ground, except when singing.

MacGillivray’s warblers are migratory and spend their summers in temperate forests in the western United States, and in boreal forests of west Canada. In autumn, these birds migrate to Central America, where they stay in temperate shrublands for the winter.

MacGillivray’s Warblers pluck insects and other arthropods from foliage and branches within their dense habitats. They take some prey on the ground as well. Most of their foraging is low, less than 3 feet off the ground, and they seldom forage more than 6 feet high. MacGillivray’s Warblers eat bugs, leafhoppers, weevils, beetles, bees, wasps, ants, moths, and butterflies (including larvae).
