Philadelphia Vireo (Vireo philadelphicus)

Adults are mainly olive-brown on the upperparts with yellow underparts; they have dark eyes and a grey crown. They have no wing bars and no eye ring. There is a dark line through the eyes and a white stripe just over them. They have thick blue-grey legs and a stout bill. The Philadelphia vireo is similar in appearance to the warbling vireo, but can be reliably distinguished by having much yellower underparts, and dark lores.
