Grieving chimpanzee carries around her dead baby for months at zoo in Spain

A chimpanzee has been carrying around her dead baby for months, a heartbreaking sight for visitors at a zoo in Spain.

The grieving chimp, named Natalia, gave birth to an infant ape about three months ago at Bioparc Valencia, but the baby died just days later, Miguel Casares, director general of the zoo, told Reuters. 

"She has been carrying her ever since," Casares said. "This behavior has been described in chimpanzees, not only in zoos, but also in the wild."
