Help support critical research and maintenance of the Common and Roseate Tern colonies on Great Gull Island.
ABOUT THE GREAT GULL ISLAND PROJECT

The Linnaean Society has supported Great Gull Island’s critical tern conservation work since the 1960s. Because of that investment, this tiny island in the Long Island Sound now hosts the Western Hemisphere’s largest nesting colonies of Common Terns and Roseate Terns. Learn More Here
HOW TO PARTICIPATE AS A FUNDRAISER
To ensure the continued success of this work, the Linnaean Society hosts a yearly Birdathon. Birders will form a team or bird solo while identifying as many species as possible over 48 hours. It’s the perfect way to enjoy spring birding while making a difference for critically endangered birds.

STEP THREE: BIRD YOUR HEART OUT (MAY 10th TO 11th)
