Species of mammal in Asia

The red panda (Ailurus fulgens), also known as the lesser panda, is a small mammal native to the eastern Himalayas and southwestern China. It has dense reddish brown fur with a black belly and legs, white lined ears, a mostly white muzzle and a ringed tail. Its head to body length is with a tail, and it weighs between It is well adapted to climbing due to its flexible joints and curved semi retractile claws. The red panda was formally described in 1825. The two currently recognised subspecies, the Himalayan and the Chinese red panda, genetically diverged about 250,000 years ago. The red panda's place on the evolutionary tree has been debated, but modern genetic evidence places it in close affinity with raccoons, weasels, and skunks. It is not closely related to the giant panda, which is a bear, though both possess elongated wrist bones or "false thumbs" used for grasping bamboo. The evolutionary lineage of the red panda (Ailuridae) stretches back around , as indicated by extinct fossil relatives found in Eurasia and North America. The red panda inhabits coniferous forests as well as temperate broadleaf and mixed forests, favouring steep slopes with dense bamboo cover close to water sources. It is solitary and largely arboreal. It feeds mainly on bamboo shoots and leaves, but also on fruits and blossoms. Red pandas mate in early spring, with the females giving birth to litters of up to four cubs in summer. It is threatened by poaching as well as destruction and fragmentation of habitat due to deforestation. The species has been listed as Endangered on the IUCN Red List since 2015. It is protected in all range countries. Community based conservation programmes have been initiated in Nepal, Bhutan and northeastern India; in China, it benefits from nature conservation projects. Regional captive breeding programmes for the red panda have been established in zoos around the world. It is featured in animated movies, video games, comic books and as the namesake of companies and music bands.

The origin of the name panda is uncertain, but one of the most likely theories is that it derived from the Nepali word "ponya". The word पञ्जा pajā or पौँजा pañjā means "ball of the foot" and "claws". The Nepali words "nigalya ponya" has been translated as "bamboo footed" and is thought to be the red panda's Nepali name; in English, it was simply called panda, and was the only animal known under this name for more than 40 years; it became known as the red panda or lesser panda to distinguish it from the giant panda, which was formally described and named in 1869. The specific epithet fulgens is Latin for 'shining, bright'.

The red panda was described and named in 1825 by Frederic Cuvier, who gave it its current scientific name Ailurus fulgens. Cuvier's description was based on zoological specimens, including skin, paws, jawbones and teeth "from the mountains north of India", as well as an account by Alfred Duvaucel. The red panda was described earlier by Thomas Hardwicke in 1821, but his paper was only published in 1827. In 1902, Oldfield Thomas described a skull of a male red panda specimen under the name Ailurus fulgens styani in honour of Frederick William Styan who had collected this specimen in Sichuan. DNA sequencing of 132 red panda faecal samples collected in Northeast India and China also showed two distinct clusters indicating that the Siang River constitutes the boundary between the Himalayan and Chinese red pandas. They probably diverged due to glaciation events on the southern Tibetan Plateau in the Pleistocene.

The placement of the red panda on the evolutionary tree has been debated. In the early 20th century, various scientists placed it in the family Procyonidae with raccoons and their allies. At the time, most prominent biologists also considered the red panda to be related to the giant panda, which would eventually be found to be a bear. A 1982 study examined the similarities and differences in the skull between the red panda and the giant panda, other bears and procyonids, and placed the species in its own family Ailuridae. The author of the study considered the red panda to be more closely related to bears. A 1995 mitochondrial DNA analysis revealed that the red panda has close affinities with procyonids. Further genetic studies in 2005, 2018 and 2021 have placed the red panda within the clade Musteloidea, which also includes Procyonidae, Mustelidae (weasels and relatives) and Mephitidae (skunks and relatives). supplemented by bamboo shoots, Actinidia strigosa fruits and seasonal berries. In this national park, red panda droppings also contained remains of silky rose and bramble fruit species in the summer season, Actinidia callosa in the post monsoon season, and Merrilliopanax alpinus, the whitebeam species Sorbus cuspidata and tree rhododendron in both seasons. Droppings were found with 23 plant species including the stone oak species Lithocarpus pachyphyllus, Campbell's magnolia, the chinquapin species Castanopsis tribuloides, Himalayan birch, Litsea sericea and the holly species Ilex fragilis. In Nepal's Rara National Park, Thamnocalamus was found in all the droppings sampled, both before and after the monsoon. Its summer diet in Dhorpatan Hunting Reserve also includes some lichens and barberries. The red panda's metabolic rate is comparable to other mammals of its size, despite its poor diet. The red panda digests almost a third of dry matter, which is more efficient than the giant panda digesting 17 per cent.

At least seven different vocalisations have been recorded from the red panda, comprising growls, barks, squeals, hoots, bleats, grunts and twitters. Growling, barking, grunting and squealing are produced during fights and aggressive chasing. Hooting is made in response to being approached by another individual. Bleating is associated with scent marking and sniffing. Males may bleat during mating, while females twitter. During both play fighting and aggressive fighting, individuals curve their backs and tails while slowly moving their heads up and down. They then turn their heads while jaw clapping, move their heads laterally and lift a forepaw to strike. They stand on their hind legs, raise the forelimbs above the head and then pounce. Two red pandas may "stare" at each other from a distance. As the reproductive season begins, males and females interact more, and will rest, move, and feed near each other. An oestrous female will spend more time marking and males will inspect her anogenital region. Receptive females make tail flicks and position themselves in a lordosis pose, with the front lowered to the ground and the spine curved. Copulation involves the male mounting the female from behind and on top, though face to face matings as well as belly to back matings while lying on the sides also occur. The male will grab the female by the sides with his front paws instead of biting her neck. Intromission is 2–25 minutes long, and the couple groom each other between each bout. Litters typically consist of one to four cubs that are born fully furred but blind. They are entirely dependent on their mother for the first three to four months until they first leave the nest. They nurse for their first five months. The bond between mother and offspring lasts until the next mating season. Cubs are fully grown at around 12 months and at around 18 months they reach sexual maturity. Roundworms, tapeworms and coccidia were also found in red panda scat collected in Rara and Langtang National Parks. Fourteen red pandas at the Knoxville Zoo suffered from severe ringworm, so the tails of two were amputated. Chagas disease was reported as the cause of death of a red panda kept in a Kansas zoo. Amdoparvovirus was detected in the scat of six red pandas in the Sacramento Zoo. Eight captive red pandas in a Chinese zoo suffered from shortness of breath and fever shortly before they died of pneumonia; autopsy revealed that they had antibodies to the protozoans Toxoplasma gondii and Sarcocystis species indicating that they were intermediate hosts. A captive red panda in the Chengdu Research Base of Giant Panda Breeding died of unknown reasons; an autopsy showed that its kidneys, liver and lungs were damaged by a bacterial infection caused by Escherichia coli.

The red panda is primarily threatened by the destruction and fragmentation of its habitat, the causes of which include increasing human population, deforestation, the unlawful taking of non wood forest material and disturbances by herders and livestock. and clearcutting decreases the ability of some bamboo species to regenerate. Threats identified in Nepal's Lamjung District include grazing by livestock during seasonal transhumance, human made forest fires and the collection of bamboo as cattle fodder in winter. Vehicular traffic is a significant barrier to red panda movement between habitat patches. In Myanmar, the red panda is threatened by hunting using guns and traps; since roads to the border with China were built starting in the early 2000s, red panda skins and live animals have been traded and smuggled across the border.

The London Zoo received two red pandas in 1869 and 1876, the first of which was caught in Darjeeling. The Calcutta Zoo received a live red panda in 1877, the Philadelphia Zoo in 1906, and Artis and Cologne Zoos in 1908. In 1908, the first captive red panda cubs were born in an Indian zoo. In 1940, the San Diego Zoo imported four red pandas from India that had been caught in Nepal; their first litter was born in 1941. Cubs that were born later were sent to other zoos; by 1969, about 250 red pandas had been exhibited in zoos. The Taronga Conservation Society started keeping red pandas in 1977. In 1978, a breed registry, the International Red Panda Studbook, was set up, followed by the Red Panda European Endangered Species Programme in 1985. Members of international zoos ratified a global master plan for the captive breeding of the red panda in 1993. By late 2015, 219 red pandas lived in 42 zoos in Japan. The Padmaja Naidu Himalayan Zoological Park participates in the Red Panda Species Survival Plan and kept about 25 red pandas by 2016. By the end of 2019, 182 European zoos kept 407 red pandas. Regional captive breeding programmes have also been established in North American, Australasian and South African zoos. In Nepal's Taplejung District, red panda claws are used for treating epilepsy; its skin is used in rituals for treating sick people, making hats, scarecrows and decorating houses. It has been featured on stamps and coins issued by several red panda range states. Anthropomorphic red pandas feature in animated movies and TV series such as The White Snake Enchantress, Bamboo Bears, Barbie as the Island Princess, DreamWork's Kung Fu Panda franchise, Aggretsuko and Disney/Pixar's Turning Red, and in several video games and comic books. It is the namesake of the Firefox browser and has been used as the namesake of music bands and of companies. Its appearance has been used for plush toys, t shirts, postcards and other items.
