Short, plain English definitions of terms used across PandasWise. Each links to the page where the idea matters most.

Ailuridae

The family that contains the red panda, its only living member. See red panda family.

Ailuropoda melanoleuca

The scientific name of the giant panda, roughly "black and white cat foot".

Ailurus fulgens and Ailurus styani

The Himalayan and Chinese red pandas, treated as two species by some scientists since a 2020 genomic study, and as one species by the current IUCN assessment.

Bamboo flowering

Many bamboo species flower only after decades, all at once over large areas, and then die. Mass flowering can cause local food shortages for pandas. See diet.

Bleat

A friendly, lamb like call that giant pandas use as a greeting. See panda sounds.

Captive breeding

Breeding animals in zoos and breeding centres, as a safety net population and for research. China's captive giant panda population was 808 at the end of 2025.

Carnivora

The order of mammals that includes bears, cats, dogs, weasels and both pandas. Membership reflects ancestry, not diet.

Ecological corridor

A strip of habitat that reconnects separated populations so animals can move and breed between them. See Giant Panda National Park.

Crepuscular

Most active at dawn and dusk. Red pandas are mainly crepuscular.

Culm

The woody stem of a bamboo plant. Giant pandas eat culms; red pandas mostly avoid them and eat leaves and shoots.

Delayed implantation

A pause between fertilisation and the embryo attaching to the uterus. It explains why giant panda pregnancies range from 90 to 180 days and red panda pregnancies from about 93 to 156 days.

Dormancy (torpor)

A temporary drop in metabolic rate to save energy. Red pandas can do this in severe cold; giant pandas do not hibernate.

Estrus

The short period when a female can conceive. In giant pandas it lasts only two to three days a year.

Habitat fragmentation

The breaking up of continuous habitat into isolated patches by roads, farms, dams and other development. A key long term threat to both pandas.

IUCN Red List

The International Union for Conservation of Nature's global list of species' extinction risk. Categories include Least Concern, Near Threatened, Vulnerable, Endangered and Critically Endangered.

Panda loan (cooperation agreement)

The arrangement under which zoos outside China host giant pandas, typically for about 10 years, with funding going to conservation and research. See where to see pandas.

Pseudo thumb (false thumb)

An enlarged wrist bone covered by a fleshy pad that both pandas use like a thumb to grip bamboo. See giant panda body.

Scent marking

Leaving scent from glands on trees, rocks or the ground to communicate. Giant pandas use a gland under the tail; red pandas also have glands between their footpads.

Umbrella species

A species whose protection also protects many others sharing its habitat. WWF describes the giant panda this way.

Ursidae

The bear family. The giant panda is a member; the red panda is not.

Vulnerable

An IUCN threatened category meaning a high risk of extinction in the wild. The giant panda has been Vulnerable since 2016.
