When to expect hooded mergansers in Ohio

Hooded Mergansers live in Ohio all year. Snow and sub-freezing stretches are routine; Carolina Chickadees hold the south and Black-capped the north. That makes the cold months the time your yard matters most to them.

Humid continental; cold winters and warm summers, with Lake Erie moderating the north coast.

Nesting in Ohio

Across Ohio, hooded mergansers typically nest from February–May. Plan around that window: January for setup, May for clean-out.

Warm, humid summers; western Lake Erie marshes are a major migration stopover.

Have boxes cleaned and mounted before January — hooded mergansers 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 May.
