When to expect American in Connecticut

American Kestrels live in Connecticut all year. Snowy winters with regular nor'easters; feeders carry chickadees, titmice and juncos through January and February. That makes the cold months the time your yard matters most to them.

Humid continental with maritime moderation along Long Island Sound.

Nesting in Connecticut

Across Connecticut, American typically nest from March–June. Plan around that window: February for setup, June for clean-out.

Warm, humid summers; peak nesting runs May through July.

  • Have boxes cleaned and mounted before February — 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.
