This Mexican Jay was spotted at the Chiricahua National Momument, 35 miles southeast of Willcox, Arizona.

Mexican Jay groups may number from 5 to 25 individuals, and may contain several active nests within one territory. Only the socially paired group members engage in nest-building, incubation, and brooding. All group members do virtually everything else, including alarm calling, mobbing, and feeding the young. Some jays feed at several nests within the territory, others feed at only one, and still others do not feed any young at all.
Genetic studies have shown that parentage within a Mexican Jay group is complicated, with most nests containing young sired by different males. Most of the extra-pair young were fathered by males within the group that did not help in nest building and did not appear to be paired.
