Seasonal Guide

Who is in the yard, and when — month by month in Western Pennsylvania

Western Pennsylvania's bird life shifts dramatically across the four seasons. Year-round residents share the yard with summer breeders, winter visitors, and migrants just passing through. Here is what to expect each season — and why.

Summer June — August

The yard is at full capacity from June through August. Summer residents are nesting, year-round birds are raising second broods, and the feeder becomes a family affair as adults bring fledglings to learn the food sources. Watch for the awkward, spotted young birds and listen for the relentless begging calls.

Fall September — November

Fall is a quiet reversal of spring: the summer residents leave, winter visitors begin arriving, and the yard settles into its cold-season rhythm. Hummingbirds leave by mid-September. The first juncos often appear before the leaves are down. Blue Jays move through in noisy flocks during October.

Winter December — February

Winter is the feeder season. The summer visitors are gone, the yard is quiet between visits, and the birds that remain are the dependable core of the year-round community. Chickadees, nuthatches, woodpeckers, and juncos work the feeders steadily. The cardinal male in snow is one of the more reliable aesthetic rewards of a western Pennsylvania winter.
