Best Birds to See by Season Across the Lower 48

The bird year in the Lower 48 has four distinct seasons, each with its own stars, its own pace, and its own gear. A retiree who knows the rhythm gets the most reward from a hobby that rewards patience. The Cornell Lab of Ornithology and the National Audubon Society both publish seasonal calendars that work as a starting framework. The framework below covers the continental US between the Canadian border and the Gulf Coast and focuses on what a senior birder can reasonably see from a yard, a city park, a state park, or a national wildlife refuge.

Spring runs from mid-March to early June. The headline event is warbler migration. Warblers are small, bright songbirds that move from Central and South America to breeding grounds in the US and Canada. The peak two weeks in the eastern US fall between April 25 and May 10, and the peak in the central US runs from May 5 to May 20. Magee Marsh in Ohio, High Island in Texas, Central Park in New York, and Pelee in Ontario are the famous spring migration hotspots. A retiree who cannot travel still gets a daily show as backyard trees host yellow-rumped warblers, black-throated green warblers, and rose-breasted grosbeaks for one to two weeks before they push north.

Summer runs from mid-June to mid-August. The pace slows. Many birds are sitting on nests, the males stop singing as soon as eggs hatch, and the leaves are thick enough to hide most movement. The summer star birds are the breeders that nest in the local area: bluebirds raising second broods, indigo buntings on power lines, scarlet tanagers in hardwood forests, and chimney swifts circling at dusk over town. Summer is the right season for early-morning walks before the heat and for evening porch sits with a hummingbird feeder.

Fall runs from late August to mid-November. The two big stories are hawk migration and warbler return. Hawk Mountain in Pennsylvania, Cape May in New Jersey, and Hawk Ridge in Minnesota count tens of thousands of raptors during peak days. Senior birders find hawk-watching especially friendly because the birds pass overhead and a comfortable folding chair, a thermos, and binoculars are the entire kit. Warblers return south in fall but in muted plumage, which makes identification more challenging. Sparrows arrive in October and stay through winter.

Winter runs from mid-November to mid-March. Ducks, geese, swans, and grebes fill local lakes and reservoirs. Many retirees find that winter is their favorite season because waterfowl are easier to identify than warblers, they sit still on open water, and the cold weather concentrates them in fewer locations. Common winter species in the Lower 48 include mallards, northern shovelers, ring-necked ducks, hooded mergansers, bufflehead, and tundra swans. The Christmas Bird Count, run by the Audubon Society every December, is the largest citizen-science event in birding and welcomes new participants of any skill.
