Vireo, << VIHR ee oh, >> is the name of a group of small birds found in forests and thickets of the Americas. Vireos are greenish or grayish above and white or yellow below. Most live in tropical regions. But several species nest in the United States and Canada.
Red-eyed vireo
The most familiar vireo in eastern North America is the red-eyed vireo. The bird’s red eyes can only be seen when it is very close. People can recognize this vireo by the white stripe bordered by black above the eyes. The bird’s song sounds conversational. It is also called preacher bird because it repeats its song continually during the spring and summer. The yellow-throated vireo has bright yellow underparts. In summer, this bird migrates from tropical regions to the eastern half of the United States and Canada.
Yellow-throated vireo
Vireos build cup-shaped nests that hang from forked branches in the trees. The female lays two to four white eggs marked with a few dark specks near the large end. Vireos eat mainly insects.
