When to expect rusty blackbirds in Alaska

Rusty Blackbirds are summer residents in Alaska, arriving shortly before nesting begins in June and leaving after the young are independent.

Subarctic interior, temperate rainforest in the Southeast panhandle, and Arctic tundra on the North Slope.

Nesting in Alaska

Across Alaska, rusty blackbirds typically nest from June–July. Plan around that window: May for setup, July for clean-out.

A short, explosive summer with near-continuous daylight compresses nesting into a few weeks.

  • Rusty Blackbirds don't use nest boxes. Keep dense native shrubs and trees such as paper birch, white spruce, tamarack for nest sites.
  • Delay heavy pruning of shrubs until after July.
