The pinyon jay (Gymnorhinus cyanocephalus) is a primary seed disperser of pinyon pines (Pinus edulis and P. monophylla). Both the pinyon jay and the pinyon pines are experiencing significant decline. While the pinyon jay is a species of management value and conservation concern, little is known about its fecundity, among-flock dispersal, and population differentiation. We initiated genetic studies in pinyon jays using a hybridization enrichment technique to isolate seven polymorphic microsatellite repeats (AAAG and GATA) from the pinyon jay genome. A locus from the Mexican jay (Aphelocoma ultramarina) that amplifies robustly in pinyon jays is also reported. These eight loci revealed moderate to high diversity in an Arizona population of pinyon jays (4-36 alleles and H O 0.42-0.90). As in other species, tetranucleotide repeats produced easily resolved amplification products.
