Silverback gorilla Monta gets irritated by his neighbor's chimps. #4/6 CHIBA ZOO 千葉市動物公園ゴリラモンタ（0271）

Описание: Filmed: Feb 2023

This video was filmed in the morning before the gorillas go to the outside exhibits. As I entered the indoor exhibit viewing area, both Monta and Rola were sitting on the second floor/step of their exhibits, respectively. Once I appeared, they knew it was the time to get ready for going outside. They came down and started pacing back and forth to check the off-exhibit gate to the outside enclosures. Monta watches something from the keeper's door. You will find out what he is watching in the video. Gigio, the female chimpanzee, intimidates Monta from a small window. Monta gets mad. Soon after the chimpanzees started their breakfast, Monta moved to the off-exhibit room to wait for the gate to be opened.

About Western Lowland Gorilla
Gorilla gorilla gorilla
Habitat: The most widespread gorilla subspecies and can be found across more than 700,000 km² of central and West Africa.
Lifespan: 35 yrs in the wild ( to 60 yrs in captivity)
IUCN Red List : Critically Endangered
It is the smallest of the four gorilla subspecies, which also include the Cross River gorillas, Grauer’s gorillas, and mountain gorillas. It has shorter black-brown hair, longer arms, and a more prominent ridge along their brow. The adult males, called silverbacks, have silvery-grey hair on their backs and thighs. Their heads are large and pointed, with a sagittal crest forming the back of the top of the head. Its population has been decreasing due to poaching and disease. The estimated population in 2013 was almost 362,000 individuals (IUCNredlist.org). Fewer than 150,000 western lowland gorillas remain in the wild (gorillas.org).

MONTA ♂
DOB: 1984/09/25 in Spain or 1986 in Africa?
Ownership: Chiba Zoo
• 1987: Monta and Momoko were transferred from Spain to Japan. (age 1 or 3?)
They were kept at Aritake Chojuten Co. Ltd., the animal dealer, until they moved to Chiba Zoo in 1993.
• 1993/03: He and Momoko were transferred to Chiba Zoological Park.
NB: The credibility of his birth info is uncertain.

Monta and Momoko grew up together. They were infants when they arrived in Japan. However, due to the allegation of illegal trade, they spent a few years at the animal dealer's place until the allegation was cleared. He desperately needs a companion to live as his kind. He's been living alone most of his adult life. From 2009 until 2010, the zoo tried pairing up Monta and Rola several times. It didn't go well. Since then, he has been all alone. The system of changing keepers at short intervals is problematic because it leads to a lack of technical training and hinders the management of the gorillas' physical and mental health. Although it has been more than 30 years since the zoo began keeping gorillas, unfortunately, both manpower and facilities are not in place to be able to manage gorillas in a group.

ROLA ♀
1977/09/21
POB: Beppu Cable Rakutenchi, Japan
Sire: Gonta｜Dam: Rirako
Rearing: Hand-reared
Ownership: Ueno Zoo
• 1977/09: Rola was born and was being hand-reared in a vet's house. No trial was attempted to return her to Rirako.
• 1980/11: Transferred to Tobu Zoo
Basically she was living alone, but her keeper played with her so she wouldn't feel lonely.
• 1993/10: Transferred to Ueno Zoo and lived with her mother, Rirako, and other gorillas.
• 2008/12: She and Kenta were transferred to Chiba Zoo and lived with him until he passed away in 2016.

Rola has difficulty in communicating with other gorillas. Especially when she is put with a silverback, she becomes ill, except with an individual like Kenta, who had no interest in gorillas. She loves sunbathing. She occasionally exhibits abnormal behaviors such as coprophagy, licking urine, and regurgitation and reingestion. Rola always searches for earthworms as her companions. But they have a short life span, plus they disappear in cold weather. I hope the zoo will consider the option of Rola living with other small animals. It may help solve her abnormal behaviors and loneliness.
