These jays are evolving into two biological populations on the same island, in oak and pine habitats. More evidence of the start of sympatric speciation in birds, without "geographical" isolation. There is a link near the bottom to a UCBerkeley site with index of different modes of geographic-based ("-patric") speciation.
