The crowned sifaka (Propithecus coronatus) is a type of sifaka that lives only in western Madagascar. This part of the world faces big problems because of human activities that harm nature and its amazing variety of animals and plants. The crowned sifaka is a kind of lemur and is about the same size as the Golden-crowned sifaka. It can be up to a meter (about 3 feet) long, with its tail making up about half of that length.
These sifakas live in trees, climbing and jumping from branch to branch. They mostly eat leaves, fruits, and flowers. Sadly, their homes are being destroyed by human activities, which is why the IUCN (International Union for Conservation of Nature) says they are critically endangered. To help them, conservation plans need to include the ideas and needs of local people.

About the Crowned Sifaka
What is a Crowned Sifaka?
The crowned sifaka was once thought to be a type of Verreaux's sifaka or Von der Decken's sifaka. However, after scientists studied their skulls in 2007, they realized it was its own unique species. Sometimes, you might see crowned sifakas with darker fur. This happens when they mix with other sifaka species nearby. So far, only two darker forms have been seen.
What Does it Look Like?
The crowned sifaka is a medium-sized sifaka. It measures about 87 to 102 centimeters (34 to 40 inches) long. Its tail is about 47 to 57 centimeters (18 to 22 inches) long. Males usually weigh between 3.5 and 4.5 kilograms (7.7 to 9.9 pounds). Females are a bit heavier, weighing 3.5 to 5.0 kilograms (7.7 to 11 pounds).
This sifaka has a creamy white body. It might have hints of golden brown near its shoulders, upper chest, and back. Its head is a dark chocolate or black color, with white ear tufts. Their face is dark grey and has no hair. They also have a white tail. Sometimes, they have a pale patch across the bridge of their nose. The color of crowned sifakas can vary, especially in the southern parts of their home range.
Where Crowned Sifakas Live
Crowned sifakas live in the mangrove forests and dry forests of northwest Madagascar. They can be found between the Mahavavy River and Betsiboka River in the north. Their home extends south to areas with many small forest patches around the Tsiribihina River, Mahajilo River, and Mania River. They haven't been seen further south than a place called Ambolando. The Mania River is thought to be the southern edge of their range, where they meet another sifaka species, P. verrauxi.
In 2014, scientists estimated there were between 4,000 and 36,000 crowned sifakas in total. They live in groups of 2 to 8 individuals. These numbers are still uncertain because not all of their habitat has been explored. Sadly, their population has dropped by at least 80% in the last 30 years. It is expected to drop by another 80% in the next 30 years.
Crowned Sifaka Lifestyle
Daily Life and Diet
The crowned sifaka is a diurnal animal, meaning it is active during the day. They spend most of their time resting. The rest of their day is spent finding food. They usually stay in the upper parts of large trees. Depending on the season, they eat young or old leaves, ripe and unripe fruits, and many flowers.
These sifakas are very important for their habitat. When they eat fruits, they spread the seeds through their droppings. This helps new plants grow and keeps the forest healthy.
Social Life and Family
Crowned sifaka groups usually have between 2 and 8 individuals. Each group has a balanced number of males and females. There is usually one dominant female in each group. They often groom each other, play, and communicate using scents and calls.
They reproduce seasonally. Pregnancy lasts about 5 to 6 months. Females can have babies only every 2 to 3 years. Not much is known about their reproduction in the wild. Most of what we know comes from sifakas living in zoos, like the one in Paris.
Protecting Crowned Sifakas
Why They Are Endangered
The crowned sifaka lives in a very small area, and their populations are broken up into many small groups. This is a big problem for their survival. Their homes are being destroyed, and forests are being cut into smaller pieces. People also use "slash and burn" farming, where they cut down and burn forests to clear land. Some sifakas are captured illegally for the pet trade, and some are hunted for food.
These problems, combined with how slowly they reproduce, make it very hard for the species to recover. The IUCN Red List has listed the crowned sifaka as critically endangered. They are also listed under CITES Appendix I, which means international trade of these animals is forbidden. Scientists expect their population to drop by another 32% soon. This is because of habitat fragmentation, which means forest pieces become isolated. Over time, these isolated forest parts lose the resources the sifakas need.
Conservation Efforts
Some larger groups of crowned sifakas live in protected areas. However, many parts of their home range are not explored because they are considered "dangerous" areas. It is very important to study these areas to help the sifakas survive long-term. Conservation efforts should be put in place in these areas. This will help protect the different color variations of P. coronatus and allow scientists to study them more closely.
A political crisis in Madagascar in 2009 led to more lawlessness. This caused an increase in sifaka poaching, as they were hunted for food. To protect these animals, local people need to be more involved in conservation efforts. We also need to learn more about the species. It is important to protect the remaining suitable habitats and try to connect forest fragments again. The first successful breeding of crowned sifakas in a zoo happened in 1994 at the Paris Zoological Park. This was part of the European Endangered Species Programme (EEP), which helps protect endangered animals.
