When to expect downy woodpeckers in Idaho
Downy Woodpeckers 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 insect larvae in goldenrod galls and bark; suet, peanuts and sunflower at feeders.
Semi-arid sagebrush plains along the Snake River and forested mountains to the north and center.
Nesting in Idaho
Across Idaho, downy woodpeckers typically nest from April–June. Nest site: excavates its own cavity in dead wood; uses roost boxes in winter. Females lay 3–8 eggs, incubate for 12 days, and young leave the nest after 18–21 days.
Hot, dry summers in the Snake River Plain and cool mountain summers.
- Have boxes cleaned and mounted before March — downy woodpeckers begin prospecting ahead of egg-laying.
- Use a 1 1/4 in round entrance on a 4 × 4 in floor, mounted 5–20 ft, box packed with wood shavings.
- Fit a pole baffle or hole guard; ventilation gaps and drainage holes are essential.
