When to expect brown creepers in Ontario

Brown Creepers live in Ontario all year. Cold, snowy winters; feeder flocks are dominated by chickadees, nuthatches, woodpeckers and finches. That makes the cold months the time your yard matters most to them: their winter diet shifts toward overwintering insects; some suet.

Humid continental in the south, boreal and subarctic in the north; most backyard birding happens in the southern Great Lakes lowlands.

Nesting in Ontario

Across Ontario, brown creepers typically nest from 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.

Short, warm summers; Point Pelee and Long Point are continent-famous migration sites.

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