When to expect varied thrushes in Alberta

Varied Thrushs are summer residents in Alberta, arriving shortly before nesting begins in June and leaving after the young are independent. Through the season they feed on insects and earthworms.

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, varied thrushes typically nest from June–July. Nest site: cup against conifer trunks. Females lay 1–6 eggs, incubate for 12 days, and young leave the nest after 13–15 days.

Warm, sunny summers with long days.
