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 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) hawk migration sanctuary-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, the Peregrines are limited to urban areas at this time.

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.
