Similar species and
how were they eliminated:
The Warbling Vireos seen in the same area were only slightly yellow underneath. They also seemed less olive colored on the back and more gray.

Red-eyed Vireos have a red eye and are larger bulkier birds. They also do not have much yellow underneath.
Previous experience with this & similar species: We have seen several Philadelphia Vireos in Ontario, Canada and Texas since 1993. We've also seen many Red-eyed Vireos in 13 different states since 1988. And as for Warbling Vireos, we've seen thousands of them, in many different areas.
