When to expect vesper sparrows in Colorado

Vesper Sparrows are summer residents in Colorado, arriving shortly before nesting begins in May and leaving after the young are independent.

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, vesper sparrows typically nest from May–July. Plan around that window: April for setup, July for clean-out.
