Birdathon is one of our major fundraisers. It is similar to a walkathon or marathon, except participants raise money for Denver Audubon by birding (not walking or running, whew!).

Proceeds fund our spring school, family, bird banding, and conservation programs. Team members collect pledges from family, friends, co-workers, and anyone else who wants to support your team and our awesome organization. Our goal is to raise $35,000.

There are three ways to participate:

Form a team

Organize a team of people who can all bird on the same day during May (it doesn’t matter what day in May, you pick). Before your team’s day, collect pledges from sponsors: friends, family, coworkers, anyone! Count the number of bird species the entire 24 hours of your team’s day! To register a new team, fill out the form below.


Sign up for a team

Current teams are listed below. If you would like to join one of the teams listed, please email Rhonda and let her know. We will send you sample letters to help you raise funds.

Support a team

Just click on any one of the donate links below to support your preferred team. If you don’t want to donate online, please mail a check to us at 9308 S. Wadsworth Blvd. Littleton, CO 80128.

What Makes a Team?

We have multiple team categories available for everyone’s ability and comfort level:

  • Green – walking or biking to bird
  • Group – 1 team of 10 or less who physically bird together
  • Large Group- 1 team of 10 or more must physically bird together 

We are asking each team to use eBird to record your bird lists and then share them with denveraudubon (1 word, no spaces). Please put your Team Name in the Comments line so we know which list(s) go with which team.

Don’t use eBird? Use this paper entry form. This way we can post Birdathon status much faster and rev up the competition!

Awards will be made to the top team in each category for total pledges collected and for most bird species seen in a 24 period.
