These rare bears are the only species of bear native to South America. Mature males, called silverbacks, have a silvery white saddle that appears around 12 14 years of age. An adult male weighs between 136 and 227 kg (300 to 500 lbs) and stands up to 1.8 m (6 ft) tall. Males are considerably larger than females. Gorillas are the largest apes, but western lowland gorillas are the smallest gorillas. The arm span of these apes can be more than two feet. Fun Fact: The western lowland gorilla is the only subspecies kept in zoos, with very rare exceptions. Cross River gorillas are scattered in at least 11 groups across the lowland montane forests and rainforests of Cameroon and Nigeria, an area of 3,000 square miles, or about twice the size of Rhode Island. They love exploring and climbing trees in their outdoor yard alongside their mother, 4-year-old Brienne. This is exactly what western lowland gorillas (Gorilla gorilla) have adapted to do. Gorillas have dark brown to black fur and black skin. Cubs Ian and Sean are getting bigger every day, and now have a healthy appetite for solid foods. Mountain gorillas have significantly longer hair than their conspecifics, while western gorillas have brown, not black, hair on their heads, and eastern gorillas have longer faces and broader chests than western gorillas (Rowe 1996 Nowak 1999). It’s been half a year since the Smithsonian’s National Zoo and Conservation Biology Institute celebrated the arrival of two Andean bears, and the cubs are as cute as ever!īorn last November, the Zoo’s rambunctious pair of Andean bear cubs first ventured out of their cubbing den and into their outdoor habitat area in mid-March. Summary: A new study reveals one of the enigmas related to the social behavior of the western lowland gorilla (Gorilla gorilla gorilla) in. As part of the Species Survival Plan, our Western Lowland Gorilla family has made a significant contribution to the population in the last few years.
