Hartford Audubon Society

The Hartford Audubon Society, founded in 1909, is nonprofit organization dedicated to wildlife conservation and education. Hartford Audubon manages several wildlife sanctuaries, participates in conservation advocacy, conducts bird censuses, and offers field trips, lectures, and other programming. It is a partner in the Hartford Urban Bird Treaty and the Connecticut Bird Atlas.

History
The Hartford Audubon Society was founded in 1909 as the Hartford Bird Study Club. The club's initial aims included advancing ornithological knowledge, protecting birds, and "interesting the general public" in the welfare of birds. The club began offering lectures on birds and conservation in 1909 and guided walks in 1911. It started the Hartford Christmas Bird Count in 1909.

The club has participated in conservation advocacy since 1909, including advising senator George P. McLean on the Migratory Bird Treaty Act.

Club members began bird banding in the 1920s, which flourished under E. Alexander Bergstrom’s leadership in the 1940s–1960s.

The club changed its name to the Hartford Audubon Society, Inc. in 1965. The organization's mission has broadened beyond birds to emphasize wildlife conservation.
