When to expect wood ducks in Ontario

Wood Ducks 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.

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, wood ducks typically nest from April–June. Plan around that window: March for setup, June for clean-out.

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

  • Have boxes cleaned and mounted before March — wood ducks begin prospecting ahead of egg-laying.
  • Use a 4 × 3 in oval entrance on a 10 × 18 in floor, mounted 6–20 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.
