Birdathon 2019

What is Birdathon?

The Birdathon is an annual fundraising event that involves all Denver Audubon supporters, their friends, family, co-workers, and others in one of America’s most popular hobbies and the number one sport: bird watching! And the great part is you don’t have to be an expert birder to participate.

3 Ways You Can Participate:


Count birds within a continuous 24 hour period – give or take – and collect pledges from sponsors: friends, family, coworkers, your auto mechanic, businesses, and anyone else you can think of. You don’t have to travel far and wide, and you don’t have to do the full 24 hours on your Birdathon. You can count birds at your feeders over the course of a day, or you can go all out and visit all the parks in Denver region. You choose whether you want to do a marathon Birdathon or just a sprint.


Many teams are heading out in May to locations throughout Denver and beyond. Just give us a call to register for one of those listed below or to sponsor one of these teams. Each team member must raise at least $50 to support their team. Call 303-973-9530 or email for more team details.


Pledge your support to one of the teams that will be out in the field counting birds. Pledges can be based on the number of species you see, or you can pledge a flat amount.

All contributions to the Birdathon are tax deductible and support the Audubon Society of Greater Denver. Donations can be based on the number of species seen, or they can be a flat amount.
  • Get your pledges lined up before the day you select to conduct your outing. These may be either as dollars per species or a lump sum. Some donors may even seek to challenge you further, offering extra dollars for every species you find breeding!
  • Plan your outing during any continuous 24 hour period in May for the best weather and to the habitats where you are likely to find a variety of birds.
  • Conduct your tally (species seen or heard only, no need to count individuals) within any period during  May in Colorado.
  • Let your supporters know how you did, and let them share in your excitement while you collect the pledged amounts. Let them know everything you saw, the surprises you found, including the missed “sure bets” you thought you had pinned down, and the excuses you generate en route (e.g “our navigator fell asleep so we were lost for an hour”, “we were so mesmerized by the Bobolink that we couldn’t tear ourselves away”. etc)
  • All pledges are tax deductible and donors will, upon request, be given a receipt.
