- Typically from May to July in Glacier National Park
- Females lay 4-6 pale blue eggs
- Incubation period: About 14 days
- Both parents participate in feeding the young
-
Nestlings fledge after 20-25 days
-
Nesting Locations in the Park:
- Open meadows near scattered trees or forest edges
- Areas with sufficient insect populations for feeding young
