Gorillas build new nests every night for several reasons. Firstly, it keeps them safe from predators, as they can create a new nest in a different location each night. Secondly, it helps to maintain hygiene, as gorillas are known to defecate in their nests and building a new one each night prevents the accumulation of waste. Finally, it may also provide a way for gorillas to mark their territory, as the location of their nests can signal to other gorillas where they have been. Overall, building new nests each night is a natural behavior for gorillas and serves multiple purposes.

When was the last time you heard good news about an animal species? Despite the bald eagle and wolf populations recovering in the United States, the number of animals on the endangered species list has increased significantly in recent years. Great apes such as gorillas, chimpanzees, bonobos, and orangutans are among the endangered animals due to poaching and deforestation in Africa. In 2006, Ebola virus caused the gorilla population to plummet. It is estimated that the virus killed 5,000 gorillas in one area and possibly 25% of the world’s gorilla population.
There are four subspecies of gorillas: eastern lowland, western lowland, mountain, and cross-river gorillas. Western lowland gorillas primarily inhabit rainforests in Western and Central Africa, including Congo, Gabon, and Central African Republic. Twenty years ago, population surveys revealed that this subspecies was critically endangered with less than 100,000 remaining.
In August 2008, the Wildlife Conservation Society conducted a survey of the western lowland gorilla subspecies and discovered at least 125,000 living in a densely forested area of the Congo known as the “green abyss”. This nearly inaccessible swampy landscape insulates the gorilla’s habitat, and the Ebola virus has yet to reach the area. Despite being the largest of the great ape species, gorillas are difficult to track due to changing locations every day in search of food. So, how did the surveyors determine the population number of these apes?
FAQ
1. What are gorilla nests?
Gorilla nests are makeshift beds made from branches, leaves, and other vegetation. They are built by gorillas to sleep in at night, and they serve as a kind of shelter from the elements.
2. Why do gorillas build new nests every night?
Gorillas build new nests every night as a way to stay safe and avoid predators. By building a new nest each night, they help ensure that their scent doesn’t linger in one spot for too long, making it less likely that predators will find them.
3. How long does it take a gorilla to build a nest?
It typically takes a gorilla anywhere from 10 to 30 minutes to build a nest. They use their hands and feet to gather and arrange leaves and branches into a comfortable sleeping spot.
4. Do all gorillas build nests?
Yes, all gorillas build nests. Even young gorillas will start building their own nests when they reach a certain age.
5. How do gorillas choose where to build their nests?
Gorillas are very selective about where they build their nests. They look for a spot that is sheltered from the wind and rain, and preferably near a food source. They also try to avoid areas that are too close to other gorilla groups.
6. Do gorillas ever reuse their nests?
While gorillas typically build new nests every night, they will sometimes reuse a nest if they find one that is still in good condition. This usually happens if they are in an area with limited resources and need to conserve energy.
7. How do researchers study gorilla nests?
Researchers study gorilla nests by examining the size, shape, and location of the nests. They can also analyze the composition of the nests to determine what materials the gorillas used to build them.
8. What can we learn from gorilla nests?
Gorilla nests can tell us a lot about the behavior of these animals. By studying the location and composition of the nests, researchers can learn about gorilla habitat preferences and migration patterns. They can also use nest data to estimate gorilla population sizes and monitor the health of gorilla populations over time.
