This circuit through many of Pennsylvania's habitats takes me back to my teenage days of birding across the Keystone State. In order to find as many birds as possible, we visited the Lower Susquehanna River Valley, successional barrens near State College, hilltops and streams in the ridge-and-valley region, shrubby grasslands, montane wetlands, broadleaf forest, hemlock groves, the lair of a very famous groundhog at Punxsutawney, and even the Grand Canyon of Pennsylvania.
We rounded up an exciting suite of songbirds including warbler superstars like Kentucky, Mourning, Prothonotary, Golden-winged, Cerulean, and Blackburnian. Additional highlights came in the form of up-close Henslow's Sparrows, a daytime Barred Owl, displaying American Woodcock, and chanting, territorial Eastern Whip-poor-wills. Rarities just kept popping up during our week together, too - in addition to more expected species, it was pretty special to find Red Crossbills, Philadelphia Vireo, Olive-sided Flycatcher, and Least Bittern.
Thanks for joining me on this short-and-sweet visit to Pennsylvania, and I hope to see you back out in the field soon.

Heard and seen at a few different riverine sites (including our lunch spot along the Juniata River).

Fairly common in open and edge habitats (such as the Frog Pond at Bald Eagle SP).
CHESTNUT-SIDED WARBLER (Setophaga pensylvanica)
Wonderfully common in central and northern PA, with some great sightings in the Scotia Barrens and elsewhere.
BLACKPOLL WARBLER (Setophaga striata) [*]
We heard singing migrants a few times, but they proved devilishly tough to spot this time.
