A vireo is a small songbird belonging to the family Vireonidae. These birds are typically found in North and Central America, with some species migrating to warmer regions during winter. Vireos are known for their distinctive, melodious songs and are often seen in wooded areas, where they forage for insects and fruits. There are about 50 species of vireo, including the red-eyed vireo and the white-eyed vireo. They have a stout body, a short tail, and a strong bill, which helps them catch prey. Vireos are often recognized by their greenish or grayish plumage, making them blend well with their natural habitats.
