with Partners in Flight to identify rapidly declining species and produce the first North American Landbird Conservation Plan. Lab staff also worked with multiple partners to create the first-ever State of the Birds report in March 2009. The Lab's Neotropical Bird Conservation Program is gathering baseline data about bird populations in Mexico, where many North American birds spend their winters, and helping colleagues in other countries with conservation training and resources. The Cornell Lab of Ornithology led the scientific arm of the search for the ivory-billed woodpecker, overseen by the U.S. Fish and Wildlife Service from 2004 to 2009. Lab scientists are currently involved with partners from industry, government agencies, and non-governmental organizations in setting research priorities to better understand the impact of wind power facilities on birds and bats. Bioacoustics research The Lab's Bioacoustics Research Program (BRP) creates remote recording devices used by researchers in projects around the world. These autonomous recording units (ARUs) consist of a hard drive, housing, and microphone array that can be mounted in a forest or anchored to the ocean floor. ARUs have been used in the Elephant Listening Project in Africa, studies of whales, and in the search for the ivory-billed woodpecker. BRP has also developed sound-analysis software programs called Raven and Raven Lite. Engineers are working on programmable radio tags to track birds and other animals for longer periods of time and to follow bird migrations. Media archives From its earliest days, the Cornell Lab has had a special interest in bird and animal sounds. Founder Arthur Allen and his students were pioneers in the field, recording the first bird songs on a film sound track. The Macaulay Library has since expanded and is now the world's premier scientific archive of natural history audio, video, and photographs. The library hosts over 14 million audio, video and photographs . Macaulay Library archivists continue to mount expeditions to collect wildlife sounds, images, and video from around the world to expand the archive. Information science The Information Science unit creates the underlying structure that makes the Cornell Lab's citizen-science projects work. It also converts massive amounts of data into charts, maps, and tables. Computer programmers at the Lab built the infrastructure for the Birds of North America Online and are now coordinating the Avian Knowledge Network, an unprecedented effort to link bird data records kept at institutions all over the Western Hemisphere.
