In British Columbia, hooded mergansers are present through the warm months, arriving around February and heading south again by June.
These windows are set by latitude: British Columbia sits in the northern part of this species' range, so timing here runs later than the continental average — the season starts later this far north and the birds wait for it. In any given year, weather can move the first arrivals by a week or two either way.

Getting ready before they arrive
The week before February is the time to act. Have feeders cleaned, filled and out by early February — the first hooded mergansers into British Columbia are scouting for reliable food, and a station that's ready early gets added to their route.
Hooded mergansers nest in cavities, so boxes need to be up and cleaned before arrival — a box mounted after they've claimed territories will usually sit empty until next year. Hooded Merganser nest box dimensions and mounting →
Once nesting begins around March, adults switch to protein-rich food for their young and visits to feeders become quick and purposeful. Expect the busiest activity at dawn.
