Western Warbling Vireo Similar Species Comparison

A small, chunky songbird with a thick, straight, slightly hooked bill. Medium-sized for a vireo, with a fairly round head and medium-length bill and tail.

Forages by plucking insects from twigs and leaves.

Adult

A mid-sized, gray-and-white vireo. Moves slowly through small branches, looking around carefully for insects. Note fairly thick bill and dark line through eye that fades out before it meets the bill.

Extremely similar to Eastern Warbling Vireo and best separated by voice. Western Warbling Vireos often have a darker, smaller bill and a longer white supercilium (stripe over the eye), but no single character holds for separating all Eastern and Western Warbling Vireos.

Grayish above and whitish below, with some yellow on the sides.

Adult

Often best located and identified by its complex warbling song.

Feeds mostly on insects but also eats some small fruits, especially during the nonbreeding season.

Breeds in deciduous or mixed woodlands and uses a wide array of scrubby and wooded habitats the rest of the year.
