Warbling Vireo
Vireo gilvus
Summary 4
The warbling vireo (Vireo gilvus) is a small North American songbird. They are mainly olive-grey on the head and upperparts with white underparts; they have brown eyes and the front of the face is light. There is a white supercilium (stripe from beak over the eye). They have thick blue-grey legs and a stout bill. Western birds are generally smaller and have darker grey crowns. They range in length from 4.7 to 5.1 inches long. While the COSA technically lies within the Warbling Vireo's breeding habitat, they tend to select mountain climates for nesting and so have been seen in the COSA only from April to May and August to September.
