Useful Hints
- Historically, the Mountain Bluebird depended for its nest sites on tree cavities excavated by woodpeckers, but the increased provisioning of nest boxes has created new breeding opportunities.
- While showing off nest cavities, males give their most elaborate display: sing on or near the structure housing the nest cavity and at the entrance, and fly back and forth between a perch near the female and the nest cavity itself (sometimes this is accompanied by male copulation attempts).
- Only the female builds the nest. The male sometimes acts as if he is helping, but he either brings no nest material or he drops it on the way.
