This female African lion is getting ready for a nap, which is typical of their nocturnal behavior. They rest about 20 hours a day. When in the wild, the female lions hunt together for the pride while the male protects the cubs and then he will dominate the kill site. Interestingly, the female will isolate herself during birth and nurture the newborns for the first six to eight weeks. Then, she returns to the pride where motherhood becomes a shared responsibility with other females. This lioness is at the Oakland Zoo in California.
