Where tidal river wetlands meet rolling ridges and the forested uplands of the Catskills, Eastern New York offers one of the state’s most balanced birding landscapes. The Hudson River supports marshes, mudflats, and open channels that attract waterfowl, shorebirds, and Bald Eagles, while reservoirs and backwaters add sheltered habitat for loons, grebes, and migratory ducks. Grasslands provide breeding space for meadowlarks and sparrows, and extensive hardwood forests shelter thrushes, woodpeckers, and warblers. On the plateaus and summits of the Catskills, cool spruce–fir stands add a northern element to summer birding and sweeping vantage points for fall migration. Seasonal rhythms are pronounced: spring brings colorful passage along river corridors, summer showcases diverse breeding from marshes to ridges, fall features hawk flights and mixed flocks, and winter concentrates birds along open river reaches. With exceptional access from major towns, this varied region is easy to explore year-round.
