What is the Delaware Bird-A-Thon?

The Bird-A-Thon is a fundraiser much like a walk-a-thon. Donate directly, or sign up as many pledge sponsors as you can. Then, during any single 24-hour period between May 1 through May 9, 2021, bird anywhere in the state of Delaware, count as many species as you can, and raise money for conservation!


a team

Grab some of your birding friends, or make some new ones, and compete to raise the most money, or see the most species during one 24-hour period in Delaware between May 1-9, 2021.


a team

Don’t want to create your own team? Donate per bird seen to one of the delaware birding teams and cheer them on during their intense 24-hour big day to see as many birds as possible.
