The Ridgefield Library will host a presentation on Preserving Plum Island — home to more than 200 resident and migratory bird species, about a quarter of all birds known in the United States, 57 of which are listed as in urgent need of conservation.

The event will take place Monday, May 22, from 6:30 to 8 p.m.

Chris Cryder, special projects coordinator for Save the Sound and the outreach coordinator for the Preserve Plum Island Coalition, will present a short film produced for PBS, Conservation of a Precious Island, starring Sam Waterston as well as the latest efforts to protect the island.

This presentation is co-sponsored by the Ridgefield Library, the Ridgefield Conservation Commission, the Woodcock Nature Center, and the Norwalk River Watershed Association, which is hosting the talk for its annual meeting.
