Dark-eyed Juncos in Pennsylvania

Dark-eyed Juncos 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 grass and weed seeds.

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

Across Pennsylvania, juncos typically nest from May–July. Nest site: cup on the ground, hidden under roots, banks or overhangs. Females lay 3–5 eggs, incubate for 11–13 days, and young leave the nest after 9–13 days.

Warm summers; bluebirds typically raise two broods.

• Dark-eyed Juncos don't use nest boxes. Keep dense native shrubs and trees such as paper birch, sugar maple for nest sites.
• Delay heavy pruning of shrubs until after July.
