Red Panda
The red panda (Ailurus fulgens), also called the lesser panda or firefox, is a small mammal that lives in the trees of the temperate mountain forests of the eastern Himalayas and southwestern China, in Nepal, Bhutan, northeastern India, northern Myanmar and the Chinese provinces of Tibet, Yunnan and Sichuan. Despite its name, it is not a close relative of the giant panda: it is the only living member of its own family, Ailuridae, and its nearest relatives are raccoons, skunks and weasels. Bamboo leaves and shoots make up most of its diet, and it adds fruit, acorns, blossoms, eggs and insects when it finds them. Its thick reddish fur, white face markings and long ringed tail make it easy to recognize, and on cold nights it wraps that tail around its body like a blanket. Solitary and most active at dawn, dusk and night, it spends much of the day asleep in the branches. Habitat loss, poaching and disease spread by dogs have made it Endangered, and its numbers keep falling.
What is a red panda?
The red panda (Ailurus fulgens) is a small, tree climbing mammal of the Himalayas and southwestern China, about the size of a large house cat. It is also called the lesser panda, and its reddish coat earned it the nickname firefox, the animal that the web browser is named after. Many people think it is a kind of raccoon, fox or small bear, but it is none of those. Genetic studies place it in its own family, Ailuridae, of which it is the only living member, inside a larger group called Musteloidea that also includes raccoons, skunks, weasels and otters. So its closest living relatives are raccoons and skunks, not foxes or bears, and it is not closely related to the giant panda at all. The two share a name, a taste for bamboo and a false thumb, but they evolved those traits separately. In fact, the red panda had the name first. It was described by Thomas Hardwicke in 1821 and named Ailurus fulgens, which means shining cat, by Frédéric Cuvier in 1825, decades before Western scientists knew of the giant panda. When the giant panda was described later, it borrowed the name, and the original panda became the lesser one.
Himalayan and Chinese red pandas
Scientists have long recognized two forms of red panda. The Himalayan red panda lives in Nepal, Bhutan, Sikkim and the Darjeeling hills, and the Chinese red panda, sometimes called Styan's red panda, lives further east, in Myanmar and in southwestern China. The Chinese form usually has a redder face with less white, darker reddish fur and more clearly marked rings on its tail, although the colors vary from animal to animal. In 2020 a large genomic study led by Chinese researchers and published in Science Advances concluded that the two forms are different enough to count as separate species, Ailurus fulgens and Ailurus styani, which split a few hundred thousand years ago. A study by the Zoological Survey of India in 2021 found that the Siang River in Arunachal Pradesh seems to be the dividing line, with Himalayan red pandas to the west and Chinese red pandas to the east, which means India is home to both. Not everyone accepts the split yet, and the IUCN still assesses all red pandas together as a single species. For conservation the difference matters, because if there are two species, each one is rarer than the red panda as a whole, and zoos now try to keep the two forms apart when they breed them.
How big is a red panda?
A red panda is about the size of a large house cat. Its head and body measure 51 to 64 centimeters (20 to 25 inches), and its bushy tail adds another 28 to 49 centimeters (11 to 19 inches), so from nose to tail tip an adult can reach about a meter. Adults usually weigh 3 to 6 kilograms (7 to 13 pounds), and males and females are about the same size, although their thick coat makes them look heavier than they are. The fur is reddish brown on the back, dark brown or black on the belly and legs, and the tail has alternating red and pale rings that help it blend into the branches. The face is mostly white, with reddish tear marks running from the eyes to the mouth, and the ears are large, pointed and edged in white. Even the soles of the feet are covered in dense fur, which keeps the paws warm on snow and ice. Red pandas have short legs, sharp claws that can partly pull back like a cat's, and flexible ankles that can rotate, which lets them climb down tree trunks head first. On the ground they walk with a slow, rolling gait, but in the trees they move with real skill.
Where do red pandas live?
Red pandas live in a narrow band of temperate mountain forest that runs along the eastern Himalayas and into southwestern China. Their range covers Nepal, Bhutan, the Indian states of Sikkim, West Bengal (in the Darjeeling hills) and Arunachal Pradesh, the far north of Myanmar in Kachin State, and the Chinese provinces of Tibet, Yunnan and Sichuan. The IUCN places them between 2,500 and 4,800 meters above sea level (about 8,200 to 15,700 feet), in forests of fir, oak, maple and rhododendron with a dense understory of bamboo. They like steep slopes near water, with fallen logs and old trees full of hollows where they can rest and raise their cubs, and they move up and down the mountains with the seasons. China is thought to hold the largest share of the population, often estimated at around 6,000 to 7,000, while an IUCN based estimate for Nepal in 2015 gave only 317 to 582. In Bhutan, the first national survey, published in 2024, identified 302 individuals from droppings collected in just 6 percent of the country and found red pandas in 19 of its 20 districts. In Myanmar they are known only from Kachin State, where camera traps in the Imawbum mountains filmed them for the first time in 2014.
What do red pandas eat?
Bamboo is the center of the red panda's diet. It eats mostly the tender leaves and, when they appear in spring and summer, the young shoots, picking the most nutritious parts of the plant. Bamboo is hard to digest, and the red panda has the short, simple gut of a carnivore with no special chambers to break down plant fiber, so it absorbs only a small part of what it eats. To make up for it, a red panda eats a large amount each day and can spend many hours feeding. It also saves energy in every way it can. Its metabolic rate is unusually low for a mammal of its size, and in cold weather it curls into a tight ball, wraps its tail around itself and lowers its body temperature and metabolism even further. Although it lives mostly on bamboo, it is technically an omnivore. Depending on the season it adds fruit, berries, acorns, roots, flowers, lichens, mushrooms, bird eggs, insects and sometimes small birds or rodents. To hold bamboo stems while it chews, it uses an enlarged wrist bone, the radial sesamoid, that works like a sixth finger. Zoos have found that red pandas also have a strong taste for sweet things, and they can taste some artificial sweeteners that most animals cannot detect.
Are red pandas nocturnal?
Red pandas are mostly crepuscular and nocturnal: they are busiest at dawn, at dusk and during parts of the night, and spend much of the day asleep in the trees. They nap stretched out along a branch when it is warm, or curled up with the tail over the face when it is cold, and they often sunbathe in the morning on high branches. Outside the breeding season they live alone. Each red panda keeps a home range of a few square kilometers, which it marks with urine, droppings and scent from glands around the tail and on the soles of its feet, so others know who has passed by. They communicate with a range of soft sounds, including squeals, twitters and a short call that keepers describe as a huff quack. They are excellent climbers, sleep and rest in trees and escape into the branches when danger appears. If cornered, a red panda stands up on its hind legs, raises its front paws to look bigger and may hiss or swipe with its sharp claws, a pose that looks funny to people but is a real threat display. Red pandas do not hibernate. In winter they simply slow down, sleep more and live on the energy they save.
Newborn red pandas: cubs and lifespan
Red pandas mate in winter, usually between January and March, and the female is receptive for only a day or so. Pregnancy lasts about 112 to 158 days, because the fertilized egg can wait before it attaches to the womb, a process called delayed implantation. Most cubs are born between June and August, in a nest of leaves, grass and moss that the mother builds inside a hollow tree, a rock crevice or a tangle of roots. Litters have one to four cubs, most often one or two. A newborn red panda weighs only about 110 to 130 grams (4 to 4.5 ounces), is covered in soft buff or gray fur and cannot see or hear. Its eyes open at around two to three weeks, and the red color comes in gradually over the first months. The mother raises the cubs alone. She spends a lot of time with them at first and later leaves the nest to feed, coming back to nurse and clean them, and she may move them to a new nest to keep them safe. Cubs first leave the nest at about three months, are weaned at around six to eight months and stay near their mother until they are close to a year old. Red pandas live about 8 to 10 years in the wild and up to about 15 years in zoos.
Can red pandas be pets?
No. Videos of red pandas playing and tumbling have made many people want one, but red pandas are wild animals, they are an endangered species and keeping one as a pet is illegal in almost every country. They are listed in Appendix I of CITES, the strictest level, which bans international commercial trade, and they are protected by law in all five countries where they live. A red panda offered for sale online is either a scam or the product of the illegal wildlife trade, which takes animals from forests where every one counts. Red pandas also make terrible pets. They need cool temperatures, large amounts of fresh bamboo every day and space to climb, they are solitary and easily stressed, and they mark their territory with strong smelling scent and droppings. They can bite and scratch hard when they feel threatened. Even accredited zoos keep them only as part of coordinated breeding programs that track the genetics of every animal, and in some of these programs, such as the one at the Darjeeling zoo in India, red pandas bred in captivity have been released back into the wild. The best way to help red pandas is to protect the forests where they still live, not to take them out of them.
What threatens red pandas?
Red pandas face pressure from several directions at once. The biggest is the loss and breakup of their forests. Mountain forest is cleared for farms, roads, villages and hydropower projects, and what remains is thinned by the collection of firewood, timber and bamboo, which removes the understory they need for food and the old trees they use for dens. Livestock is a growing problem. Herds of cattle and yaks graze inside red panda forests, trampling bamboo, and the herders' dogs chase and kill red pandas and can pass on diseases such as canine distemper, which is deadly to them. Poaching continues too. Red pandas are caught in snares set for other animals, and they are also hunted for their fur, which is used for hats and decoration; in Nepal, police and conservation groups regularly seize red panda hides being smuggled toward China and Myanmar. Live animals are also taken for the illegal pet trade. Because the remaining populations are small and isolated, losing even a few animals can push a local group toward disappearing. Climate change adds another layer of difficulty, since rising temperatures are expected to push the bamboo zone higher up the mountains, and bamboo die offs after mass flowering can leave red pandas with little food.
How many red pandas are left in the wild?
Nobody knows exactly how many red pandas are left, because they are shy, live in remote, steep forests and are hard to count. The IUCN has listed the red panda as Endangered since its 2015 assessment, published that year and corrected in 2017, because its population is thought to have fallen by about half over the last three generations, roughly 18 years, and it is still declining. An estimate based on the lowest known densities across the available habitat gives about 10,000 animals, and the commonly cited figure is fewer than 10,000 in the wild, although older estimates went as high as 16,000 to 20,000. Red pandas are protected by law in all five range countries and are listed in Appendix I of CITES. Conservation work is growing. In Nepal, the Red Panda Network trains and pays local forest guardians who monitor red pandas and remove traps. In India, the Padmaja Naidu Himalayan Zoological Park in Darjeeling released nine red pandas bred in captivity into Singalila National Park between 2022 and 2024, and three of the females have since had five cubs in the wild. Bhutan completed its first national survey in 2023. Zoos around the world keep an international breeding program, and every year International Red Panda Day, on the third Saturday of September, raises awareness and funds.
