2 weekends ago, several other observers and I saw and photographed an unquestionable Philadelphia vireo in Burlington's Greenmount Cemetery. We were fortunate that the bird was singing a duet with a red-eyed vireo in an adjacent tree, allowing for a comparison of the subtle differences in their songs. The only other Philadelphia vireo I've seen in Vermont was on the summit ridge of Mount Mansfield last summer. Chris Rimmer caught it in one of his nets, affording everyone extreme closeup views as the bird was examined and banded.
