The Connecticut Ornithological Association (COA) is the only statewide organization dedicated specifically to Connecticut’s birds, birders, and birding.

Please support COA by purchasing a membership.

The Connecticut Ornithological Association is the only statewide organization devoted to birds and birding in Connecticut. Since its founding in 1984, its membership has grown to well over 500 people who range from beginning birders to professional ornithologists.

The only requirements for membership in COA are an interest in birds and the ability to enjoy yourself. Does that sound like you? Then join us!
