'''Common Name:''' Red-eyed Vireo <br>
'''Scientific Name:''' Vireo olivaceus

'''Size:''' 4.7-5.1 inches (12-13cm)

'''Habitat:''' North and South America; the breeding habitat is open wooded areas across Canada and the eastern and northwestern United States. These birds migrate to South America, where they spend the winter. The Latin American population occurs in virtually any wooded habitat in their range. Most of these are residents, but the populations breeding in the far southern part of this species' range (e.g. most of its range in Argentina, Uruguay, Paraguay and Bolivia) migrate north as far as Central America.

This vireo is one of the more frequent American passerine vagrants to Western Europe, with more than one hundred records, mainly in Ireland and Great Britain. 

'''Status:''' Least Concern. '''Global Population:''' 140,000,000 mature individuals. It is subject to nest predation by cowbirds. This species has undergone a small or statistically insignificant increase over the last 40 years in North America.

'''Diet:''' Insects; primarily caterpillars and aphids. Vireos glean insects while moving along branches. It kills larger prey by crushing or beating it against branches and holds food with its foot while eating.  Occasionally vireos will eat berries, especially before migration. 

'''Breeding:''' Sexes are alike. Immature vireos have brown eyes and yellower under parts than the adults.

The nest is a cup in a fork of a tree branch and is made of twigs, bark strips, grasses, pine needles, and lichen held together with spider web. The inner lining is comprised of grasses, plant fibers, and hair. Dull white speckled with reddish brown eggs are laid.

'''Cool Facts:''' One of the most common birds of the Eastern forests, the Red-eyed Vireo is heard far more than it is seen. It appears to be endlessly repeating the same question and answer.  Among bird species it holds the record for most songs given in a single day- more than 20,000 songs.

Red-eyed Vireos living year-round in South America may be a separate species.
