Bringing Birders Together Statewide
Founded in 1984, Connecticut Ornithological Association is an all-volunteer organization with the mission of promoting interest in Connecticut birds and collecting, preparing, and disseminating the best available scientific information on the status of Connecticut birds and their habitats. While COA is not primarily an advocacy organization, we work actively to provide scientific information and support other conservation organizations in the state.
