Ospreys, fish migration are topics of Lyme-Old Lyme Earth Day event Tuesday

Lyme-Old Lyme High School will host an “Earth Day 2014” event at 7 p.m. Tuesday on “Spring Migrants and Our Coastal Food Chain: Alewife, Menhaden and Osprey.”

Conservation biologist and ornithological expert Dr. Paul Spitzer will discuss his study of osprey in the lower Connecticut River estuary. Inspired by his mentor Roger Tory Peterson and Rachel Carson’s "Silent Spring," Spitzer was part of the movement that banned DDT in 1972 and documented its correlation to the thinning of osprey egg shells. Spitzer is now collecting data related to the overfishing of menhaden, a primary food source for osprey chicks.

State Department of Energy and Environmental Protection biologist Steve Gephard will discuss efforts to restore and protect the fish that migrate between Long Island Sound and the Connecticut River and its tributaries.

Participants with information tables will include: Lyme-Old Lyme High School’s Environmental Club, the Lyme and Old Lyme Land Trusts, the Old Lyme Conservation and Open Space Commissions, the Tributary Mill Conservancy, the Potapaug Audubon Society and the CT River Gateway Commission.
