Cassin's Vireo

Vireo cassinii

Length: 6 in. (14 cm )

Occurring in the tops of mixed deciduous and coniferous forests, the Cassin\'s Vireo is most easily located by its persistent song. Its cup-like nest is suspended in the fork of a small branch and made of grass and lichens. Insects make up most of the diet, but in mid-winter some fruits are eaten.

The four-digit banding code is CAVI.
