When to expect hooded mergansers in North Carolina
Hooded Mergansers live in North Carolina all year. Black-capped Chickadees and other northern birds are confined to the highest mountains; lowlands stay mild. That makes the cold months the time your yard matters most to them.
Mountains, Piedmont and coastal plain differ sharply — cool, snowy highlands to mild, humid coast.
Nesting in North Carolina
Across North Carolina, hooded mergansers typically nest from February–May. Plan around that window: January for setup, May for clean-out.
Warm and humid in the Piedmont and coast; cooler at elevation.
- 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.
