When to expect green-tailed towhees in Colorado

Green-tailed Towhees 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.
