Colorado Bluebird Project

Improving bluebird populations

The Colorado Bluebird Project operates under the guidance of the Audubon Society of Greater Denver 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.

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 nest box construction and repair of older nest boxes. 

Educational Presentations

​Natural Resource Specialist, Barbara Spagnuolo, conducts two education presentations in late winter to prepare residents for the start of the Colorado Bluebird Project season. Learn about the program and how you can help bluebirds in Castle Rock or in your own backyard at the open house with comprehensive monitoring training offered separately.

The presentations for the 2018 season have already been held. Please check back for more information on future presentation dates.

2017 Season wrap up

If you were unable to attend our end-of-the-season reception and presentation, but want to know how the season ended up, view the Natural Resource Specialist's presentation. Also, if you were a 2017 volunteer and are curious about the specific site you monitored, we can provide you with a site summary. Contact 720-733-2294 or email us for more information.

2018 Season Information

The 2018 season is well under way and we have volunteers signed up to monitor all of our sites. If you are interested in learning more about the Colorado Bluebird Project or volunteering to be a nest-box monitor in the future, please feel free to fill out a volunteer interest form to get on our email notification list.

To apply for the program, complete the 
individual volunteer application and volunteer waiver and indemnification form, and then submit it to the POST Partners volunteer coordinator by email.

Feel free to download our Colorado Bluebird Project Volunteer Training Manual as a reference for either your backyard monitoring or as one of our nest-box monitoring volunteers. We encourage those installing nest boxes in their own yards to follow these guidelines.

Thanks to these 2017 Colorado Bluebird Project volunteers. These more than 80 volunteers contributed 513 hours to help with the program and increase our Bluebird and Tree Swallow populations in Castle Rock.

Sadly, we are heartbroken to announce that we did lose one of our long-time bluebird monitors this year to cancer. We will miss Carla Turner and all of her contributions to the wildlife of Castle Rock.
