When to expect juncos in Alberta
Dark-eyed Juncos live in Alberta all year. Cold winters broken by chinook thaws in the south. That makes the cold months the time your yard matters most to them: their winter diet shifts toward grass and weed seeds.
Continental — prairie in the southeast, aspen parkland in the center, boreal forest in the north and the Rockies in the west.
Nesting in Alberta
Across Alberta, juncos typically nest from June–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.
