When to expect red-eyed vireos in Colorado

Red-eyed Vireos 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, red-eyed vireos typically nest from May–July. Plan around that window: April for setup, July for clean-out.

Warm, dry days and cool nights; afternoon storms are common in July and August.
