Pennsylvania is a state spanning the Mid-Atlantic, Northeastern, Appalachian, and Great Lakes regions of the United States. Pennsylvania borders Delaware to its southeast, Maryland to its south, West Virginia to its southwest, Ohio and the Ohio River to its west, Lake Erie and New York to its north, the Delaware River and New Jersey to its east, and the Canadian province of Ontario to its northwest. It has a population of about 13 million people. The state is 274 km (170 miles) north to south and 455 km (283 miles) east to west.  It covers an area of just under 120,000 km2 (46,000 square miles) and is the 33rd-largest state in the United States, with a coastline of 82 km (51 miles)  along Lake Erie and 92 km (57 miles)  along the Delaware Estuary. Of the original Thirteen Colonies, Pennsylvania is the only state that does not border the Atlantic Ocean. The largest city by far, with nearly six million inhabitants is Philadelphia, but the state capital is Harrisburg on the Susquehanna River in the east-central region of the state.

The state has five geographical regions: Allegheny Plateau, Ridge and Valley, Atlantic Coastal Plain, Piedmont, and Erie Plain.

Pennsylvania’s diverse topography produces a variety of climates, though the entire state experiences cold winters and humid summers. Straddling two major zones, the majority of the state, except for the southeastern corner, has a humid continental climate. The southern portion of the state, including the largest city, has a humid subtropical climate. Summers are generally hot and humid. Moving toward the mountainous interior of the state, the winter climate becomes colder, the number of cloudy days increases, and snowfall amounts are greater. Western areas of the state, particularly locations near Lake Erie, can receive over 100 inches (250 cm) of snowfall annually, and the entire state receives plentiful precipitation throughout the year. The state may be subject to severe weather from spring through summer into autumn. Tornadoes occur annually in the state.

Birding Pennsylvania

Stretching from the tidal Delaware River in the southeast to Lake Erie in the northwest, Pennsylvania offers a wide variety of habitat and of bird life. Many northern warblers nest in the mountains, yet many southern species range north into the river valleys. The low-lying Piedmont in the southeastern corner hosts the only tidal marshes in the state. These marshes and mud flats, mostly confined to the John Heinz National Wildlife Refuge at Tinicum, attract shorebirds, waders, and other wetland species.

The river valleys (Delaware, Schuylkill, Susquehanna, Allegheny) provide migration corridors as well as more southerly climates. The mountains provide forested habitat for many of the neo-tropical migrants. For instance, Pennsylvania has so much forest that it has been estimated that more Scarlet Tanagers nest here than anywhere else. Many man-made and a few natural lakes attract migrating waterfowl.

Pennsylvania is home to the first, and most famous raptor migration viewpoint – Hawk Mountain Sanctuary – where thousands of raptors can be observed on migration each fall. Bald Eagles, Ospreys, and Peregrine Falcons have all made a great comeback and now nest in many areas around the state, however, Peregrines are mostly limited to urban areas. Lake Erie and especially Presque Isle State Park, provides ocean habitat for migrants and is a haven for shorebirds and waterfowl, as well as a great passerine migrant trap in both spring and fall.

    The Kittatinny Ridge is the premier raptor migration corridor in the northeastern U.S., one of the leading such sites in the world. The Sanctuary's annual counts of migrating raptors have helped assess long-term trends in raptor populations throughout eastern North America. This database has helped document subsequent rebounds in several raptor populations following decreases in the use of environmental contaminants such as DDT. Sixteen species of regular migrants include: Sharp-shinned Hawk, Cooper's Hawk, American Kestrel, Red-shouldered Hawk, and Merlin. In addition to the raptors, over 140 species of birds are recorded regularly during the fall migration. Of the top ten most abundant species nesting at the Sanctuary, eight are forest interior birds.
  • IBA Mount Zion (Piney Tract)

    WebpageSatellite View
    An area of reclaimed strip mines in central Clarion County, south of the Clarion River. The high, rolling hills, stripmined in the 1970s, have been revegetated with grasses and trees (locust and pine). Grassland habitat occupies the hilltops, transected by brushy or forested stream bottoms. Surface ponds provide some wetland habitat. At various places, small surface streams are diverted to acid mine drainage (AMD) treatment with chemicals and/or ponds and artificial wetlands. Some of the lower ponds are pollution-free and full of wildlife, including insects and amphibians. The large size of this area, particularly the contiguous fields, is a significant component to its importance to grassland birds. Bird surveys have documented notable diversity and remarkable numbers of grassland birds. At present, this is the only regular and reliable breeding site in Pennsylvania for Short-eared Owl (B- 2+ pairs). Piney Tract supports the largest Henslow's Sparrow breeding colony in Pennsylvania (approx. 100 pairs) and exceptionally high numbers of Grasshopper Sparrow (1000 pairs) and Savannah Sparrows (1,000 pairs).
  • IBA The Barrens at Scotia - SGL 176

    WebpageSatellite View

This area, adjacent to State College and PennState University, is characterized by gently rolloing terrain with Karst topography and sandy soils. The site is dominated by second-growth Chinkapin and Chestnut Oak and pitch Pine. The shrub layer is dominated by Scrub Oak, dwarf Chestnut Oak, and blueberry. There are numerous shrub/scrub areas along with old fields and ore pits. There are several wetland areas as well as the main pond (Toftrees Pond), which borders a gold course, forest, and cornfield. An unusual species of diving beetle inhabits some of the water-filled ore pits. This unique habitat is one of the largest barrens left in Pennsylvania. It harbors large numbers of Neotropical migrants during spring and fall migration. Thirty-three species of warblers have been observed including Blue-winged, Golden-winged, Tennessee, Orange-crowned, Nashville, Northern Parula, Chestnut-sided, Magnolia, Cape May, Black-throated Blue, Yellow-rumped, Black-throated Green, Blackburnian, Pine, Palm, Bay-breasted, Blackpoll, Cerulean, Black-and-white, American Redstart, and Worm-eating warblers.

  • NWR IBA John Heinz

    WebpageSatellite View
    The John Heinz National Wildlife Refuge at Tinicum is one of the most popular birding spots in Pennsylvania for good reason: it is a premier spot to find migrant waterfowl, shorebirds, herons and songbirds. Located in both Philadelphia and Delaware Counties, in the shadow of Philadelphia International Airport, this urban oasis also provides vital nesting habitat for several wetland bird species that are rare in Pennsylvania, including Marsh Wren and Least Bittern. The refuge includes the only remaining freshwater tidal marsh in the Commonwealth. The John Heinz National Wildlife Refuge at Tinicum boasts a bird list of nearly 300 species. In the fall, thousands of shorebirds and waterfowl pass through the refuge. Some waterfowl linger over the winter depending upon the availability of open water. In the spring, waterfowl pass through again, along with smaller numbers of shorebirds. During the summer nesting season the refuge hosts several nesting wetland bird species of conservation concern, including Marsh Wren and Least Bittern. The refuge is also a key habitat for songbirds, especially during the spring and fall migrations.

Trip Reports
  • 2017 [05 May] - Tom Johnson & Doug Gochfeld - Pennsylvania's Warblers & More

    Report
    I was fortunate to grow up in Pennsylvania, a bird-rich state that is frequently overlooked as a birding destination. When John Rowlett decided to retire and Field Guides stopped offering the "Virginia's Warblers" tour, I was excited to try a similar itinerary on my familiar home turf. May 2017 was the first running of our new tour, and I think that it went really well. We found 29 species of warblers and a wonderful suite of other species, even with a rainy day that posed some temporary meteorological challenges.

    Photography, including both the art and the science of, has become an integral part of my life over the past 42 years. The world of nature photography and photojournalism has opened an entire new chapter in my life. It has rekindled the “fun and intrigue” in what can sometimes become a repetitive craft. You seldom can anticipate what might be waiting around the next curve of the road or bend in the path. The subject matter is diverse but seldom restrictive and can create a test of ones patience, knowledge and photographic skills all while set within the wonder of our natural world. Mother Earth can throw you a few curves here and there, but at the same time provide limitless opportunities and endless adventure.
