When to expect American in Ontario

American Kestrels 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, American 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 — American begin prospecting ahead of egg-laying.
  • Use a 3 in entrance on a 8 × 8 in floor, mounted 10–30 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.
