When to expect house finches in Idaho
House Finchs live in Idaho all year. Cold winters with inversions in the valleys; mountain finches and Bohemian Waxwings move into towns. That makes the cold months the time your yard matters most to them: their winter diet shifts toward seeds and dried fruit; sunflower and nyjer at feeders.
Semi-arid sagebrush plains along the Snake River and forested mountains to the north and center.
Nesting in Idaho
Across Idaho, house finches typically nest from April–August. Nest site: ledges, hanging planters, dense conifers, vines and building nooks. Females lay 2–6 eggs, incubate for 13–14 days, and young leave the nest after 12–19 days.
Hot, dry summers in the Snake River Plain and cool mountain summers.
- House Finchs don't use nest boxes. Keep dense native shrubs and trees such as smooth sumac, paper birch, chokecherry for nest sites.
- Delay heavy pruning of shrubs until after August.
