When to expect violet-green swallows in Yukon

Violet-green Swallows are summer residents in Yukon, arriving shortly before nesting begins in June and leaving after the young are independent. Through the season they feed on flies and midges.

Subarctic continental with mountains, boreal forest and Arctic tundra in the north.
