Subject: Re: Apparent YELLOW-GREEN VIREO at Henderson BVP
This is certainly an interesting bird! Perhaps its species may prove to be indeterminate, particularly without additional information. Being more foolish than brave, I will wade in and say that the bill looks particularly long compared to the many western Bell’s Vireos I have seen here and particularly Arizona, but maybe the eastern race is longer billed. I would note that the second picture, the eye when blown up some does appear a little reddish. This might be an artifact of the lighting, who knows.

So I agree with Carl that more pictures/data are needed and I don’t know if Vireos are prone to any hybridization, but that could certainly yield a confusing bird like this one. In some ways, this bird reminds me quite a bit of the mystery vireo we had on the Audubon trip to Oliver Ranch recently but we didn’t have any decent pictures to put together the clues.
