The Southern Tier blends rolling hills, broad valleys, and wooded ridges along New York’s Pennsylvania border. The Susquehanna and Chemung Rivers cut through farmland and towns, creating migration corridors for waterfowl, raptors, and passerines. Reservoirs and lakes attract loons, ducks, and gulls in colder months, while extensive forests host breeding warblers, thrushes, and vireos throughout spring and summer. Grasslands and open country add kestrels and meadowlarks, contrasting with deep woods that shelter interior forest specialists. As autumn arrives, broad-winged hawk flights move along ridgelines and mixed flocks build at forest edges. Winter quiets the landscape but rewards patient exploration with finches, eagles, and hardy residents. With a balance of accessible urban parks and wilder state forests, the Southern Tier connects Appalachian character to New York’s interior, offering steady, season-shaped birding throughout the year.
