Dr. Stephen Kress, director of National Audubon Society’s Seabird Restoration Program, will give a presentation about some of the factors that limited Maine seabird populations and will discuss how techniques developed on Maine islands have led to the restoration of puffins and terns to historic nesting islands in the Gulf of Maine.

Although seabird nesting islands seem safe due to their remoteness, they are intimately connected to human activities. For example, Maine seabird nesting islands are affected by large populations of herring and great black-backed gulls that benefit from garbage and fisheries waste practices hundreds of miles from nesting islands. As scavenging large gulls increase, they deter smaller, migratory seabirds, such as puffins and terns from nesting on many of their historic nesting islands.

Dr. Kress will also discuss how techniques developed in Maine are helping seabirds worldwide. His lecture includes reviews of several case studies in seabird restoration including restoration of Common Murres in California to an historic nesting island in near San Francisco, relocation of a Caspian Tern colony in the Columbia River estuary to reduce predation on salmon smolt, and efforts to save the endangered Bermuda Petrel from rising oceans and increased frequency of hurricanes.

His presentation is on Wednesday, Aug. 3 at 5 p.m. at The Project Puffin Visitor Center, located on Main Street in Rockland. Please call to reserve a seat, 596-5566.
