remains undetermined. He was the only World War II fatality on the island. On February 2, 1945, 1st Lt. Arthur W. Kidder, Jr., a member of the 54th fighter squadron based on Attu, was test-flying a P-38 Lightning when his radio antenna broke. With low clouds in the area, he was unable to find Attu without a vector from the control tower. After a four-hour search, he spotted Buldir as he was running low on fuel and executed a wheels-up forced landing. Kidder was able to walk away from the crash with only minor injuries. Weather station personnel radioed news of his arrival, and he was picked up by a U.S. Navy vessel two days later. Kidder's wrecked plane was subsequently used for target practice by other American aircraft. In August 1994, the Aerospace Heritage Foundation of Utah, with assistance from the U.S. Air Force, recovered the wrecked P-38 from Buldir. It was restored, and is now on display at the Hill Aerospace Museum at Hill Air Force Base in Roy, Utah. Post-war In October 1956, the tanker Dulcinea, carrying of aviation fuel to the Northwest Airlines base on Shemya, went aground on Buldir. The vessel foundered and was lost. The U.S. Fish and Wildlife Service has maintained seasonal biological monitoring teams on Buldir since 1988. Their primary focus is on nesting seabirds. The data they produce is an input to assessments of the regional ecosystem, which are used in fishery management. Bird life Buldir's remoteness and the extreme difficulty of landing a boat safely on the island gave it a unique ecological history. Neither Russian nor American fur traders thought it was worth the effort to stock Buldir with Arctic or red foxes, as was done on 190 other Aleutian islands. Since the fur traders did not land, the island also escaped introduced rats. In consequence, the ground-nesting birds of Buldir continued their lives undisturbed by mammalian predators, while on other Aleutian Islands entire species were extirpated. Freedom from introduced predators allowed Buldir to become one of the largest and most diverse seabird breeding colonies in the Northern Hemisphere. The island is home to 4 million seabirds of 21 species during breeding season. The island's colonies include crested auklets and least auklets, as well as puffins, storm petrels and other species. It is one of only four known locations where red-legged kittiwakes breed. A comprehensive survey in 1975 revealed
