The Blue-headed Vireo is spread across Canada and the Eastern United States. They occupy both coniferous forests and deciduous forests. They may be found anywhere with trees that are middle-aged to mature and a high percent of canopy closure and with bushes and saplings under the trees. The Blue-headed Vireo migrates to the southern United States and into subtropical and tropical forests during the winter months. The Blue-headed Vireo eats medium to large insects, some spiders, once in a while they will also eat snails and larvae from leaves. In the winter they may eat fruit.

BEHAVIOR

 

Pairing is rapid and will include a precopulatory displays and nest-building displays where the birds will stand with a lowered head, moving their body and beak in movements that resemble nest-building. This continues until the female indicates acceptance. They are monogamous and the male chooses and protects a territory and possibly one other. A Blue-headed Vireos nest is a rounded cup hanging from a branch; it is made of spider webs, grasses, bark strips, dead leaves, hair, and moss. The Blue-headed Vireo will decorate it with birch bark and spider egg cases. The inner lining includes rootlets, conifer twigs and grass. They lay 3-5 eggs per brood.
