When to expect white-crowned sparrows in Colorado

White-crowned Sparrows are summer residents in Colorado, arriving shortly before nesting begins in May and leaving after the young are independent. Through the season they feed on insects.

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, white-crowned sparrows typically nest from May–July. Nest site: cup on or near the ground. Females lay 2–7 eggs, incubate for 11–14 days, and young leave the nest after 10 days.
