Species-typical and individually distinctive acoustic features of crow calls of red jungle fowl.

Crow calls of red jungle fowl (Gallus gallus) were analyzed for the purposes of (a) determining the extent of commonality and variability of acoustic features within and between individual roosters, and (b) characterizing the modal crow call of this species. Comparisons were made between crow calls of jungle fowl and those of domestic fowl to assess the extent to which domestication has affected these motor patterns.
