The Blue-Headed Vireo is a small songbird found primarily in the eastern regions of North America. It is known for its distinctive blue-gray head, olive-green back, and white underparts. This bird typically inhabits deciduous and mixed forests, where it forages for insects and berries among the tree branches. During the breeding season, the Blue-Headed Vireo builds its nest in shrubs or low trees, laying 3 to 5 eggs. Its song is a series of clear, whistled notes, which can often be heard during the spring and summer months. This species is part of the larger family of Vireonidae, which includes other vireos.
