Families and individuals of all ages will find this a rewarding, fun and educational way to interact with local wildlife in their community. The program begins in late March, when bluebirds return to Colorado, and runs through the end of summer. Weekly monitoring begins in April.

Volunteers are needed to help maintain and monitor nest boxes throughout the community. Registered volunteers will visit the boxes regularly on a rotating two- or three-week basis to collect important nesting data. Volunteers are also needed to help with nest box construction and repairs.

Those who decide to participate as volunteer monitors in the program will need to attend a separate training on either Wednesday, Feb. 21, from 4 to 5:30 p.m. or Thursday, Feb. 29, from 6:30 to 8 p.m. at the Millhouse.

For more than 16 years, the Colorado Bluebird Project has operated under POST Partners and Denver Audubon. The program aims to improve the vitality of native bluebird populations throughout Colorado and inform and educate the public about bluebirds. Since 2007, there have been more than 8,600 bluebirds, swallows and other native birds fledge from the boxes around Castle Rock.

The Town’s local Bluebird Project maintains and monitors 202 nest boxes at 34 different sites throughout Castle Rock. In 2023, 150 volunteers contributed 2,500 hours to help increase the bluebird and swallow populations in Castle Rock.
