We started the day on Appledore Island, just outside Portsmouth Harbor. The Shoals Marine Lab, resident there, traces its history back to 1928. Among the biologists spending the summer there this year were Dr. Elizabeth Craig, Tern Conservation Program Manager. "There are three species that I’m hoping we’re going to see today; the common tern, the roseate tern and the arctic tern." In her orientation she walks through the differences among the species, but all three are long lived, which for birds, means 10-30 year life-spans.
