In Yukon, violet-green swallows are present through the warm months, arriving around May and heading south again by August.
These windows are set by latitude: Yukon 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.

Highlighted months are when violet-green swallows are expected in Yukon. The edges of the window are the interesting weeks — first arrivals and last departures vary most from year to year.
Getting ready before they arrive
The week before May is the time to act. This species doesn't use feeders much, but water and cover matter — a clean birdbath and undisturbed shrubs make a yard far more attractive to a newly arrived bird.
Violet-green swallows 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. Violet-green Swallow nest box dimensions and mounting →
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.
