In Newfoundland and Labrador, black-and-white warblers are present through the warm months, arriving around May and heading south again by August.
These windows are set by latitude: Newfoundland and Labrador sits in the middle 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 May is the time to act. Have feeders cleaned, filled and out by early May — the first black-and-white warblers into Newfoundland and Labrador are scouting for reliable food, and a station that's ready early gets added to their route.
Once nesting begins around June, adults switch to protein-rich food for their young and visits to feeders become quick and purposeful. Expect the busiest activity at dawn.
