I expect that this hybrid has never been recorded. As I understand it, the
Warbling and the Red-eyed Vireo are not even in the same subgroup of the
genus Vireo and are probably not all that closely related. I am interested
in finding out why you thought it was a hybrid, what characters did it show?
Could it have been a Yellow-green Vireo?
