When to expect brown creepers in Colorado
Brown Creepers live in Colorado all year. Cold snaps alternate with sunny, dry thaws; heated baths are valuable because natural water freezes nightly. That makes the cold months the time your yard matters most to them: their winter diet shifts toward overwintering insects; some suet.
Semi-arid high plains in the east and the Rocky Mountains through the center, with most backyards between 5,000 and 7,000 ft.
Nesting in Colorado
Across Colorado, brown creepers typically nest from May–June. Nest site: hammock nest behind loose bark on dead trees. Females lay 5–6 eggs, incubate for 13–17 days, and young leave the nest after 13–16 days.
Warm, dry days and cool nights; afternoon storms are common in July and August.
- Brown Creepers don't use nest boxes. Keep dense native shrubs and trees such as chokecherry, ponderosa pine, gambel oak for nest sites.
- Delay heavy pruning of shrubs until after June.
