Colorado Bluebird Project

Improving bluebird populations

The Colorado Bluebird Project operates under the guidance of Denver Audubon and is offered through POST Partners in Castle Rock. This volunteer-run project aims to improve the vitality of bluebird populations throughout Colorado and to inform and educate the public about bluebirds. For more information, see the project overview sheet (PDF).

Volunteers needed

Volunteers of all ages are needed to assist with monitoring of the nest boxes from April through August. Additionally, volunteers are needed to help with maintenance and repair of older nest boxes. 

Wondering what to expect as a volunteer? Check out this slideshow featuring photos provided by our volunteers from the 2019 season.
