Because Nature Needs Heroes—Now More Than Ever

Bird-a-thon brings birders, nature-lovers, and families together—virtually and in-person—to celebrate nature and raise funds that provide essential year-round support for Mass Audubon's conservation, nature education, and advocacy work.

No matter if you join for the fun of it or for the thrill of competition (or both!), every participant is encouraged to help their team fundraise in support Mass Audubon's mission to protect the nature of Massachusetts.

Here's How It Works

This year, 13 teams representing different Mass Audubon wildlife sanctuaries or programs are raising money while helping people of all ages connect with nature in communities across the state (and beyond!).

During Bird-a-thon weekend, these teams compete head-to-head in two ways:

  1. Earning points through fun nature activities, birding, & more
  2. Attempting to identify the greatest number of bird species in 24 hours


Show your support by making a donation!

You can make a donation online to support a participant, a team, or the overall event. Not only will you be cheering them on for Bird-a-thon, your donation will also help protect the nature of Massachusetts!

The donation period for Bird-a-thon 2022 starts in April.

Participate on a Team

You don't have to be a birder to take part in Bird-a-thon!

Everyone is welcome to join a team—whether you're into birding, love exploring nature, or just want a good reason to get outside on a spring day.

Check out participant-submitted photos from last year's spectacular event in the Bird-a-thon 2021 Digital Gallery!
