When to expect hooded mergansers in British Columbia

Hooded Mergansers are summer residents in British Columbia, arriving shortly before nesting begins in March and leaving after the young are independent.

Temperate rainforest on the coast, dry interior valleys and mountains, and boreal forest in the northeast.

Nesting in British Columbia

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

Dry, warm coastal summers; hot in the Okanagan.

Have boxes cleaned and mounted before February — 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.
