About The Cover

Two low-ranking older females charge an adult male Hanuman langur to rescue an infant he has seized from its mother and severely wounded. After retrieving the infant, the older of the two defenders, “Sol,” continued to harass the infanticidal male. The infant's mother (not shown) did not participate in the rescue. See page 913.
