The members of the bird family Vireonidae - the Vireos - occur naturally in Mexico, Central America and northern South America. Most are non-migratory with the exception of a few that travel north to breed in the United States.
These small to medium-sized forest birds measure between 10 - 17 cm in length (including the tail). Vireos are plain-plumaged, mostly yellowish or greenish with varying amounts of grey, black or white.
Diet / Feeding
Most rely primarily on insects and arthropods for food, and incessantly search dense foliage in various layers for food.
