When to expect brown creepers in Pennsylvania

Brown Creepers live in Pennsylvania all year. Snow cover makes suet and heated water valuable; both chickadee species meet in a narrow hybrid zone across the south of the state. That makes the cold months the time your yard matters most to them: their winter diet shifts toward overwintering insects; some suet.

Humid continental; cold, snowy winters in the north and mountains, milder in the southeast.

Nesting in Pennsylvania

Across Pennsylvania, brown creepers typically nest from May–June. Nest site: hammock nest behind loose bark on dead trees. Females lay 5–6 eggs, incubate for 13–17 days, and young leave the nest after 13–16 days.

Warm summers; bluebirds typically raise two broods.

  • Brown Creepers don't use nest boxes. Keep dense native shrubs and trees such as black cherry, white oak, flowering dogwood for nest sites.
  • Delay heavy pruning of shrubs until after June.
