Philadelphia vireo Vireo philadelphicus

Identification Tips:

Similar Species:

Members of the Red-eyed Vireo complex have bolder supercilia that are bordered above (and below) by black stripes, red eyes as adults, and mostly white underparts. Warbling Vireo is very similar, especially fall immatures which can have quite yellow underparts. Note the pale lores of Warbling Vireo and the tendency for any yellow to be concentrated on the belly and flanks rather than the breast. Tennessee Warbler is quite similar but has a thinner pointed bill. All other vireos have wing bars.
