Citizen Science Programs

Making a difference one bird at a time.

Global Big Day

On 4 May, will you join more than 20,000 others and become a part of Global Big Day? You don’t have to commit to birding for 24 hours—an hour or even 10 minutes of watching birds makes you part of the team. Visit your favorite spot or search out someplace new; enjoy a solo walk or get some friends to join in the Global Big Day fun.

Project Feeder Watch

Project FeederWatch turns your love of feeding birds into scientific discoveries. FeederWatch is a winter-long (November-April) survey of birds that visit feeders at backyards, nature centers, community areas, and other locales in North America.

Hummingbirds at Home

Join Audubon's Hummingbirds at Home as a community scientist to help learn more about hummingbirds and how to protect them.

Nest Watch

Participating in NestWatch is easy and just about anyone can do it, although children should always be accompanied by an adult when observing bird nests.
