Pinyon jay The pinyon jay (""Gymnorhinus cyanocephalus""), historically known as the blue crow or Maximilian's jay, is a jay between the North American blue jay and the Eurasian jay in size. It is the only member of the genus Gymnorhinus, (monotypic). Its overall proportions are very nutcracker-like and indeed this can be seen as convergent evolution as both birds fill similar ecological niches. The pinyon jay is a bluish-grey coloured bird with deeper head colouring and whitish throat with black bill, legs and feet. This species occurs in western North America from central Oregon to"
