Ornithology is a branch of zoology that concerns the study of birds. Etymologically, the word ornithology derives from the ancient Greek á½ÏÎ½Î¹Ï ornis (bird) and Î»ÏÎ³Î¿Ï logos (rationale or explanation).

Most marked among these is the extent of studies undertaken by amateurs working within the parameters of strict scientific methodology.
