Red panda
A scientist by the name Brian Houghton Hodgson was one of the first people to look more deeply into the Red Panda because up until he did, there was not much known about the species. In addition to Bamboo, the Red Panda also eats fruits, tuberous roots, acorns, and beechmast. The Red Panda is not necessarily nocturnal but is classified as crepuscular which means they are active around dawn and sleep during the night and midday. Besides how they slept, Hodgson observed that they were monogamous and only breed once a year.
