Birding Southwest New Hampshire

Where the Monadnock foothills descend toward the Connecticut River Valley, Southwest New Hampshire blends upland forests, wetlands, and pastoral river country into a classic inland birding landscape. The region’s rolling hills and floodplains host a rich variety of habitats, from spruce bogs and kettle ponds to hayfields, reservoirs, and forested ridges. Spring fills orchards and valleys with migrants, summer brings warblers, flycatchers, and thrushes to the woods, and autumn draws raptors and waterfowl along mountain and river corridors. Even in winter, finches, owls, and eagles enliven the cold valleys. With its blend of accessible terrain, scenic farmland, and forested highlands, Southwest New Hampshire stands out as one of the state’s most rewarding inland regions for birding.
