Birdathon FAQ

What is the 2023 Migration Madness Birdathon?

It’s a weekend of local birding scheduled for Saturday and Sunday, May 20 and 21, 2023. The Birdathon is a fun and friendly competition to see as many species of birds as possible over that weekend.

You can find the Birdathon rules here.

The event is also a fundraiser to support bird conservation in Connecticut. Individuals will collect pledges, then look for birds over the event’s two days.

All skill levels are welcome. Whether you find 10 birds or 110 birds, you’re invited!

You can look for birds anywhere in Connecticut. Many of Connecticut Audubon’s centers will be offering guided bird walks throughout the weekend. Expert guides will help you find lots of birds to add to your Birdathon lists.

Do I have to participate both days of the Birdathon?

No! You can participate wherever and however you want. We know some people will want to bird all weekend, but others will want to participate for a day or for a few hours. It’s up to you. We just want you to get outside and enjoy the birds!

Are there prizes?

Yes! Prizes are listed here.

Grand Prize: If you see 40 or more species over the weekend and raise or contribute $40 or more, you’ll be entered in a raffle for this year’s grand prize — a beautiful carving of a Rock Ptarmigan by artist Keith Mueller. Your $10 entry fee will be counted toward the $40.
