When to expect juncos in Alaska
Dark-eyed Juncos 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 beetles, caterpillars and moths.
Subarctic interior, temperate rainforest in the Southeast panhandle, and Arctic tundra on the North Slope.
Nesting in Alaska
Across Alaska, juncos typically nest from June–July. Nest site: cup on the ground, hidden under roots, banks or overhangs. Females lay 3–5 eggs, incubate for 11–13 days, and young leave the nest after 9–13 days.
A short, explosive summer with near-continuous daylight compresses nesting into a few weeks.
- Dark-eyed Juncos don't use nest boxes. Keep dense native shrubs and trees such as paper birch, willow (bebb), dwarf birch for nest sites.
- Delay heavy pruning of shrubs until after July.
