''Gymnorhinus'' The pinyon jay (''Gymnorhinus cyanocephalus'') 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.
