A Field Guides Birding Tours Report

Pennsylvania's Warblers & More II: From Cerulean Warbler to Henslow's Sparrow

May 25-30, 2021 with Tom Johnson guiding

Even though we encountered rainy conditions at the Pine Creek Gorge, this Blackburnian Warbler and many other songbirds brightened things up for us. Photo by guide Tom Johnson.

We set out on this short loop through Penn's Woods to enjoy a diversity of songbirds, and ended up with a bounty of those and some fun bonuses along the way. Our journey took us from the Lower Susquehanna River Valley, across the Ridge-and-Valley region, into the rolling hills of the Allegheny Plateau, and even to the edge of the Grand Canyon of Pennsylvania. Songbird action was impressive during the beginning of the breeding season for PA's multitude of neotropical migrant species, with warbler highlights like Mourning, Prothonotary, Golden-winged, Kentucky, Cerulean, Canada, and more... AND we found other excellent landbirds like Black-billed Cuckoo, Henslow's Sparrow, Yellow-breasted Chat, Eastern Screech-Owl, and Eastern Whip-poor-will, too. Perhaps the biggest surprise of the tour came during our last full day when we drove through a chilling rain in Tioga County and stumbled into a roadside flock of hundreds of migrant shorebirds grounded by the storm. Whimbrel, Black-bellied Plovers, Ruddy Turnstones, Red Knots, Sanderlings, Dunlin, and Short-billed Dowitchers wheeled around and rested in a stubble field surrounded by mature forest, miles from any significant body of water! This was likely a flock that had taken off in clear conditions the previous evening from Delaware Bay and flew north into the night, eventually encountering heavy rain over northern Pennsylvania. The only solution for these embattled travelers was to drop down and land in whatever open habitat they could find, and we felt fortunate to intersect with them in the middle of their long flight north. Just amazing, and a fun capper to a great tour of Pennsylvania in spring.

Good birding,

EASTERN PHOEBE (Sayornis phoebe)

Seen almost every day; nesting under bridges and on structures in the forested parks we visited (composting toilets always seem to have a nesting pair of phoebes!).

Common around farms, towns, and cities.

Mimidae (Mockingbirds and Thrashers)

GRAY CATBIRD (Dumetella carolinensis)

Omnipresent in PA's forests and shrublands during the breeding season. The loud songs of these birds sometimes drown out the dawn chorus, making it tough to hear smaller, quieter songbirds!

NORTHERN MOCKINGBIRD (Mimus polyglottos)

Found around the Harrisburg area on our first day.

CHIPPING SPARROW (Spizella passerina)

A common triller of edge habitats across PA.

CLAY-COLORED SPARROW (Spizella pallida)

This singing bird on a regenerating strip mine in Clearfield County was a nice surprise. This midwestern species is a rare breeder in PA, so getting to hear the buzzy song and see the well-marked face of this sparrow was a treat (and a first for the tour).

Field Guides Birding Tours
Henslow's Sparrows usually impart a big-headed look. This one was singing away near Punxsutawney, Home of Punxsutawney Phil (the groundhog). Photo by guide Tom Johnson.

FIELD SPARROW (Spizella pusilla)

Icteridae (Troupials and Allies)

BOBOLINK (Dolichonyx oryzivorus)

A few individuals gurgled and fluttered over a hayfield east of Punxsutawney.

This thrush-like warbler belts out a chanting song that resounds through a huge chunk of PA's forests. We had a few nice looks along the way.

LOUISIANA WATERTHRUSH (Parkesia motacilla)

Nice views of this migrant along the stream below Bear Meadows and also on our final morning at Clarks Creek. The loud, whistled cascade of a song easily rings out over the sound of rushing water.

NORTHERN WATERTHRUSH (Parkesia noveboracensis)

Super views of the singing bird near the bridge at Bear Meadows—right up the road from the Louisiana Waterthrush, but in fairly different breeding habitats (Northern in a tangly swamp, Louisiana along a rushing stream).

GOLDEN-WINGED WARBLER (Vermivora chrysoptera)

We found singing males at both Scotia Barrens and Bald Eagle SP - this species is declining near the eastern edge of its range here in Pennsylvania, and it's a big relief to find some still holding on. We also found a male hybrid of the "Brewster's" Warbler phenotype nearby at Scotia Barrens.

BLUE-WINGED WARBLER (Vermivora cyanoptera)

A male sang "bee-bzz" in the powerline cut in the Stony Creek Valley on our final morning.


Frequently heard, with good looks in the mixed flocks we found around the Pine Creek Gorge.

PROTHONOTARY WARBLER (Protonotaria citrea)

A few singing males were radiant in bottomland forest along the Susquehanna River on our first morning.

NASHVILLE WARBLER (Leiothlypis ruficapilla) [*]

One sang from the forest at Bear Meadows.

MOURNING WARBLER (Geothlypis philadelphia)

After enjoying a male on territory near the Pine Creek Gorge, we found a migrant singing a truly bizarre song along Clarks Creek on our final morning.

KENTUCKY WARBLER (Geothlypis formosa)

A male found on the first tour in Stony Creek Valley was still present on territory and offered us some nice views. This species has declined in PA in recent years.

COMMON YELLOWTHROAT (Geothlypis trichas)

A very common warbler of field and edge habitats.

HOODED WARBLER (Setophaga citrina)

Seen on a few occasions, including at least two males at Scotia Barrens. Heard frequently from broadleaf forests.

A very common warbler in PA's forests, with plenty encountered at Scotia Barrens and the Pine Creek Gorge area.

CERULEAN WARBLER (Setophaga cerulea)

Yowza! We found a singing male above the Appalachian Trail on a ridgetop north of Harrisburg.

NORTHERN PARULA (Setophaga americana)

Our first was along the lower Susquehanna River; later, we found a pair feeding near the parking lot at Clarks Creek.


Top views were at Bear Meadows and at Colton Point SP; these are truly standout marvels of the bird world, even among the spectacular wood-warblers.

YELLOW WARBLER (Setophaga petechia)

A regular sight and sound in shrubby fields and edge habitats; good views at Sandy Ridge and Bald Eagle SP.

CHESTNUT-SIDED WARBLER (Setophaga pensylvanica)

"Pennsylvania" is right there in the Latin name, and sure enough, they are here! The second growth habitats at Scotia Barrens are primo for the species, and we saw plenty.

BLACK-THROATED BLUE WARBLER (Setophaga caerulescens cairnsi)

Buzzy-singing males and subtle females showed off at Bear Meadows and Colton Point SP.

PINE WARBLER (Setophaga pinus)

Our best view of a singing male was along the road through a stretch of pines at Scotia Barrens.

Field Guides Birding Tours
Formerly considered a warbler (!), Yellow-breasted Chat is now placed in its own family, Icteriidae. Photo by group member Kathy John.

PRAIRIE WARBLER (Setophaga discolor)

One was at the spot with the Clay-colored Sparrow in Clearfield County; another was in Stony Creek Valley near Harrisburg. This tail-pumping warbler really likes shrubby, early successional habitats.


The thin, buzzy song gives away the presence of this common north woods warbler. Especially good views at Bear Meadows.

CANADA WARBLER (Cardellina canadensis)

A female danced around in the thick understory at Bear Meadows; later, a sharply dressed male appeared in front of us at an overlook of the Pine Creek Gorge.

Cardinalidae (Cardinals and Allies)

SCARLET TANAGER (Piranga olivacea)

Snazzy red-and-black males appeared for us at Peters Mountain and Scotia Barrens, and we heard their raspy songs frequently throughout the forests we visited.

Common in many habitats.

ROSE-BREASTED GROSBEAK (Pheucticus ludovicianus)

One posed briefly at Scotia Barrens.

EASTERN COTTONTAIL (Sylvilagus floridanus)

The bunny we found repeatedly.


Just one or two crossing the roads, though we heard them chipping frequently from the woods.

Several roadside sightings - often in agricultural fields and lawns. For bonus points, we also visited Gobbler's Knob (home of Groundhog Day) while in Punxsutawney.

EASTERN GRAY SQUIRREL (Sciurus carolinensis)

AKA Pennsylvania Nut Monkey. Seen every day.

FOX SQUIRREL (Sciurus niger)

The one we saw along a roadside near Lewisburg (while searching for larks) was a bit of a surprise near the northeastern edge of the range of this large, bushy-tailed squirrel.

WHITE-TAILED DEER (Odocoileus virginianus)

Seen on most days. PA's population is quite robust!

Totals for the tour: 136 bird taxa and 7 mammal taxa
