I almost missed this one, and its a life bird for me! Yesterday I first heard, then saw this very noisy bird near the top of a tall Oak in the same location where I had seen a Philadelpia Vireo last year. I am not at all familiar with vireos and so thought this one was probably a Philadelpia as well. As I seldom use binoculars it wasn't until I zoomed in on a downloaded photo at home that I saw its red eye! Then I looked carefully for other distinguishing features of the Red-yed Vireo and saw its gray crown with a dark border lining it and pale yellow markings on its undertail and sides. This sighting is a welcome addition to my life list and my second vireo sighting.
