When to expect pine siskins in Alaska

Pine Siskins live in Alaska all year. Interior winters reach −40°F with under four hours of daylight; resident chickadees and redpolls depend on high-fat food. That makes the cold months the time your yard matters most to them: their winter diet shifts toward spruce, birch and alder seed.

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

Nesting in Alaska

Across Alaska, pine siskins typically nest from May–June. Nest site: shallow cup far out on a conifer branch. Females lay 3–5 eggs, incubate for 13 days, and young leave the nest after 14–15 days.

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

  • Pine Siskins don't use nest boxes. Keep dense native shrubs and trees such as paper birch, white spruce, black spruce for nest sites.
  • Delay heavy pruning of shrubs until after June.
