National Bird Day is an annual holiday with half a million adherents who celebrate through birdwatching, studying birds, and other bird-related activities. Bird Day was established by Charles Almanzo Babcock, the Oil City superintendent of schools, in 1894. It was the first holiday in the United States dedicated to the celebration of birds. Babcock intended it to advance bird conservation as a moral value.
