When to expect fox sparrows in Alaska

Fox Sparrows are summer residents in Alaska, arriving shortly before nesting begins in June and leaving after the young are independent. Through the season they feed on insects.

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

Nesting in Alaska

Across Alaska, fox sparrows typically nest from June–July. Nest site: cup on the ground or low in shrubs. Females lay 2–5 eggs, incubate for 12–14 days, and young leave the nest after 9–11 days.

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

  • Fox Sparrows don't use nest boxes. Keep dense native shrubs and trees such as paper birch, red-osier dogwood, western serviceberry for nest sites.
  • Delay heavy pruning of shrubs until after July.
