ATTU: THE HOLY GRAIL OF NORTH AMERICAN BIRDING. Attu, in the Aleutian Islands, the westernmost point in the United States located 1500 miles from mainland Alaska, is known worldwide as a birding mecca. It featured prominently in the hit movie “The Big Year,” and it was the target destination for an intrepid group of five Maine birders in the spring of 2012. Doug Hitchcox, Maine Audubon’s staff naturalist, will present a travelogue of photos and stories that document his amazing birding adventure into the Eastern Hemisphere, highlighted by rare species, colonies of over two million birds, song sparrows the size of robins, enduring 20-foot (and higher!) seas en route, and a bird that only recently rebounded from the edge of extinction.
