The Black-Throated Blue Warbler is well described by its name. Males are blue-grey above and white below, with a black face, throat, and sides. Females are a dull olive-green, with a narrow white eyebrow patch and usually a small, square, white with patch.
They live in the hardwood forests of the Algonquin Highlands, keeping mainly to the mid-level forest, above the ground and below the canopy. Nesting near the ground in a shrub or a young tree, the Black-Throated Blue Warbler lays an average of 4 white brown-spotted eggs. The nest is build from leaves and grass, and lined with cobwebs and hair.
Their buzzing and rising songs sound like ”zwee-zwee-zwee-zwee”. One of the tamest warblers, the Black-Throated Blue Warbler can sometimes be approached to within a metre. They remain in the area for only a few months, migrating south for the winter.
