When to expect white-breasted nuthatches in Ontario

White-breasted Nuthatchs 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 acorns, hickory nuts and seeds; sunflower, peanuts and suet at feeders.

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, white-breasted nuthatches typically nest from April–June. Nest site: natural cavities in large trees; occasionally nest boxes. Females lay 5–9 eggs, incubate for 13–14 days, and young leave the nest after 18–26 days.

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

  • Have boxes cleaned and mounted before March — white-breasted nuthatches begin prospecting ahead of egg-laying.
  • Use a 1 1/4 in round entrance on a 4 × 4 in floor, mounted 5–20 ft.
  • Fit a pole baffle or hole guard; ventilation gaps and drainage holes are essential.
  • Clean out old nests after each brood and again after June.
