ABOUT Birdathon 2023



Birds have a unique, special, and different meaning to each of us. So, too, is each of our connection with Tucson Audubon Society personal and distinct. During Birdathon, we combine the love of bird watching during spring migration with support for bird conservation.

Birdathoners are birders and social fundraisers, joining together to make a difference for the birds and habitats of Southeast Arizona. Birdathoners continue a tradition that has held strong for over 30 years! 

Each Birdathoner's personal network of supporters is what helps makes Birdathon possible. 

Birdathon donations are tax deductible to the extent allowed by law. Tucson Audubon Society is a 501(c)(3) nonprofit.
