When to expect goldfinches in Montana
American Goldfinchs are summer residents in Montana, arriving shortly before nesting begins in August and leaving after the young are independent. Through the season they feed on thistle, sunflower, coneflower and aster seeds; tree buds and maple sap in spring.
Continental — Rocky Mountain forest in the west, semi-arid Great Plains in the east.
Nesting in Montana
Across Montana, goldfinches typically nest from August–September. Nest site: tight cup in shrubs or saplings, lined with thistle or cattail down; nests late, in July–September. Females lay 2–7 eggs, incubate for 12–14 days, and young leave the nest after 11–17 days.
Warm, dry summers and a short growing season.
- American Goldfinchs don't use nest boxes. Keep dense native shrubs and trees such as paper birch, rabbitbrush for nest sites.
- Delay heavy pruning of shrubs until after September.
