Despite the similarity in their common names, giant panda and red panda are not related to each other. They belong to totally different families with no connection whatsoever. However, it's also worth noting that we usually refer to giant panda―the bear native to China―when we say panda.
In these mountains, they are found at elevations of around 3,000 meters. In winter though, they descend to an altitude of around 800 meters. The natural habitat of giant pandas is typically characterized by bamboos on which they feed.
Basically, there are two subspecies of giant panda: the Ailuropoda melanoleuca and Ailuropoda melanoleuca qinlingensis. While the former is typically black and white in color, the latter is brown and white. Of the two, the Ailuropoda melanoleuca qinlingensis, a.k.a. the Qinling panda, is endemic to the Qinling Mountains in Shaanxi province.
The Brahmaputra river acts as a geographical border between the habitat of these two subspecies. Their highly adaptable nature ensures that they are found in captivity in various parts of the world.
Other Asian countries such as India, Myanmar, and Bhutan are also home to this species, but their concentration in these countries is relatively low. The Western red panda is found in Nepal and India, while the Styan's red panda is found in southern China and northern Myanmar.
That covered the natural habitat as well as geographical range of giant panda and red panda species. While the red panda has been declared vulnerable by the International Union for Conservation of Nature (IUCN), giant panda is considered endangered.
The driving factor being habitat destruction as a result of large-scale clearance of land for farming and logging. As in the case of several other species, even these pandas are falling prey to human interference in their natural habitat.
