From the Bylaws of ECOC:

“The purposes of the Club, which was established in 1916, are to promote interest in ornithological study in Essex County, Massachusetts, and to promote conservation of birds and their habitats in Essex County. More specifically, the Club seeks:

1. To maintain a long tradition of holding an annual May bird census by canoe and on foot on and along the Ipswich River.

2. To periodically revise the official checklist of the birds of Essex County.

3. To present speakers and organize field trips consistent with the above purposes.”
