Social networker. As a member of a large permanent flock, the pinyon jay applies exceptional cognition and flexibility to its interactions. It uses at least 15 distinct calls to communicate and mediate relationships. A cooperative breeder, this jay maintains pair bonds over multiple breeding seasons. Year after year, it has acted as a vital seed disperser, but its primary habitat of pinyon-juniper woodlands is threatened by agriculture and herbicides. Is its active social life now nearing an end?
