From John J. Collins:
I went to Chimney Rock (Bridgewater, Somerset County) today and saw a PHILADELPHIA VIREO at the east end of the parking lot at noon time. In addition to that nice bird there were Red-eyed Vireo (which at one point sat right near the Philadelphia so I could make a comparison of the two species – very cooperative of them), Black-and-White Warblers, Magnolia Warbler, American Redstarts, Chestnut-sided Warbler, Common Yellowthroats, Northern Parula, Ruby-throated Hummingbirds, and, at the Hawk Watch, Ospreys, Bald Eagles (I saw at least 4), hundreds of Broad-winged Hawks, Merlins, American Kestrels, and Common Ravens.

And from Jeff Ellerbusch’s eBird comments:
“(A Philadelphia Vireo) Feeding on and around ‘suet’ tree, at Hawk Watch platform, seen by all. A second individual was seen by Chris (Aquila) seconds before, on the same tree, but flew off. These represent the 4th and 5th Philadelphia Vireos (if none are repeats) at Chimney Rock this season…WOW”
