Abstract: | Vocalizations and associated behaviour of six mated pairs of captive pinon jays (Gymnorhinus cyanocephalus) were recorded under various conditions in an effort to understand functions of the calls. One vocalization, the near, was analysed for components that would allow for individual recognition by pinon jays. Fifteen vocalizations are recognized and most are described quantitatively. Much gradation occurs within and between calls, which may allow for a subtle and complex system of communication in this highly social species. Wild flocks of pinon jays also were observed to corroborate the conclusions reached. |
