Interspecies interactions

One possible predator of gorillas is the leopard. Gorilla remains have been found in leopard scat, but this may be the result of scavenging. When the group is attacked by humans, leopards, or other gorillas, an individual silverback will protect the group, even at the cost of his own life. Gorillas do not appear to directly compete with chimpanzees in areas where they overlap. When fruit is abundant, gorilla and chimpanzee diets converge, but when fruit is scarce gorillas resort to vegetation. The two apes may also feed on different species, whether fruit or insects. Gorillas and chimpanzees may ignore or avoid each other when feeding on the same tree, but they have also been documented to form social bonds. Conversely, coalitions of chimpanzees have been observed attacking families of gorillas including silverbacks and killing infants.
