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

Proceeds fund school, family, 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. Birdathon 2021 raised over $32,000.
Can’t wait to see you next year!

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 this form.

What Makes a Team?

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

  • Backyard – seen in the area around your home
  • Green – walking or biking to bird
  • Solo – 1 person birding (larger area than Backyard or Green)
  • Group – 1 team of 10 or less who physically bird together
  • Virtual Group- 1 team but folks bird individually

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.
