Birdathon is Houston Audubon’s signature spring fundraising event—a "walk-a-thon" for birders. Participants form teams to identify as many bird species as possible within a 24-hour period between April 11 and May 11. It is a high-energy celebration of spring migration that combines community science with a mission to raise $75,000 for local conservation.

By donating, you aren’t just helping us count birds—you are helping to save them.
