What do Grizzly bears and Gorillas eat?

Grizzly bears are omnivores; they can eat anything which provides energy and nutrition. Their diet varies depending on season and availability of food sources. They extensively eat fruits, berries, nuts, tubers in summer and autumn. They also prey upon small mammals, rodents as well as elk, caribou, moose, etc. Gorillas are herbivores; they consume leaves, berries, fern, and bark.

Behavioral Traits:

Grizzly bears are solitary animals; they prefer to live alone but can be easily spotted together where there is rich availability of food. Grizzly bears only meet during mating season; family groups of mother with her cubs roam together as bears are not territorial. Gorilla is usually peaceful, shy, and amiable but when threatened they stand erect, emit growling noises and beat their chest with fists. They are territorial and can demonstrate aggression when any intruder come into their territory. Gorilla is social; they live in small bands having 5-15 individuals. Each band has its dominant gorilla which is mostly a ‘silver-back’.

Amazing facts:

  • When a gorilla reaches certain age hairs of their back falls or turn grey due to which their back appears silvery and hence they are named ‘silverbacks’.
  • Grizzly bears hibernate during winter as their food gets covered under thick snow. During that time they don’t eat, drink, urinate or defecate. They remain in their dens for about 150-210 days.
  • Both grizzly bears and gorillas have no natural predators.

Animal Duel: Who Would Win?

Gorillas and Grizzly bears are found in different halves of the world; so there is no possibility of a natural encounter between them. But if in a hypothetical situation, a fight occurs between them; it will be very ferocious. Gorilla has enormous strength whereas grizzly bear is immensely powerful; hence the fight will be exciting and interesting. As bear has large paws having sharp claws it can hurt gorilla whereas the muscular gorilla’s one blow can make grizzly bear unconscious.

It is very difficult to predict the winner; we think the gorilla’s agility and strength can outweigh the bear’s power. Hence, we cast our vote for the gorilla’s side and make it winner of this battle. What do you think, who would have won??
