When to expect merlins in Alberta

Merlins 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.

Continental — prairie in the southeast, aspen parkland in the center, boreal forest in the north and the Rockies in the west.

Across Alberta, merlins typically nest from June–July. Plan around that window: May for setup, July for clean-out.
