When to expect killdeer in Colorado
Killdeers are summer residents in Colorado, arriving shortly before nesting begins in March 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, killdeer typically nest from March–July. Plan around that window: February for setup, July for clean-out.
Warm, dry days and cool nights; afternoon storms are common in July and August.
- Killdeers 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 July.
