Ornithology (from the Greek ornis = bird and logos = word/science) is the branch of zoology concerned with the scientific study of birds. Several aspects of the study of ornithology differ from closely related disciplines, perhaps because of the high visibility and the aesthetic appeal of birds. Most marked among these is the extent of field studies undertaken by amateur volunteers working within the parameters of strict scientific methodology.
