The Colorado Bluebird Project operates under the POST Partners volunteer program and
the Audubon Society of Greater Denver to improve the vitality of native bluebird populations
throughout Colorado, with the goal of informing and educating the public about bluebirds.

This year marks Castle Rock’s sixth consecutive year of participation with this project.
Volunteers are needed for weekly monitoring of nest boxes and breeding activity from April
through mid-August at 16 different sites located at various schools, parks, open space and trails.
