Early yesterday morning I had a singing vireo at Capstan Island but wasn't sure about ID. After reviewing recording and observing sound graph, my ears believe it to be a Philadelphia Vireo. Gaps between each note are about one second longer than the similar sounding Red-eyed Vireo. Comments from Vireo aficionados are much welcomed.
