BREEDING BIRD SURVEY is done in June and are run by Migratory Bird Populations Station of US Fish and Wildlife Service. Each cooperator starts half hour before dawn. He or she then stops every half mile, listens exactly 3 minutes, and lists every bird noticed. The ordeal lasts four hours. Results are available to ornithological researchers.
PROJECT FEEDERWATCH is run by the Cornell Laboratory of Ornithology. They also have a lot of other programs.
