Yellow-green vireo The yellow-green vireo has a nasal "" call, and the song is a repetitive "veree veer viree, fee’er vireo viree", shorter and faster than that of the red-eyed vireo. This species rarely sings on its wintering grounds. This vireo occurs in the canopy and middle levels of light woodland, the edges of forest, and gardens at altitudes from sea level to 1500 m. The 6.5-cm-wide cup nest is built by the female from a wide range of plant materials, and attached to a stout twig normally 1.5–3.5 m above the ground in a tree, but occasionally up to 12 m
