The Greek root ornith- means "bird", so ornithology is the study of birds. Amateur ornithology, usually called birding or birdwatching, is an extraordinarily popular pastime in America, where over 40 million people pursue it. Roger Tory Peterson's many field guides have long been some of the amateur ornithologist's most useful tools. Amateurs often make essential contributions to serious ornithology, as in the annual Christmas Bird Count, when tens of thousands of birders fan out across North and South America to produce a kind of census of all the species in the New World.
