Why are giant pandas black and white?

Nobody can say for certain, but the best supported explanation comes from a 2017 study in Behavioral Ecology led by Tim Caro of UC Davis. It found that the panda's coat does two jobs: the white face, neck, belly and rump help it hide in snow, the black limbs and shoulders help it hide in shade, and the dark ears and eye patches are used for communication rather than camouflage. Other theories exist, and the Smithsonian and San Diego Zoo Wildlife Alliance both stress that scientists have not reached a final answer.

Why the question is hard

Almost no other mammal looks like a giant panda, so there are no obvious look alikes to compare it with. Caro's team got around this by treating each part of the body as a separate patch of colour. They scored more than 10 body areas in thousands of photographs and compared each area's darkness with that of 195 other carnivore species and 39 bear subspecies, then tested which ecological and behavioural factors best predicted dark or light fur in each area.

Finding 1: a two season camouflage

Across carnivores, white fur on the face, neck, belly and rump went with snowy habitats, and dark limbs went with shady environments. The researchers argue the panda needs both because of its diet. Bamboo cannot give it enough fat to go dormant in winter, as some bears do, so it must stay active all year, moving through habitats that range from snowy mountain slopes to dark, damp forest. A coat that half matches snow and half matches shadow is a compromise for an animal that is out and about in both. (More on this in do pandas hibernate?)

Finding 2: a face built for signalling

The head markings did not fit the camouflage pattern. Instead, the study suggests:

• Dark ears may convey ferocity, a warning to potential predators.
• Dark eye patches may help pandas recognise one another, or signal aggression to rival pandas. Eye patches vary in size and shape between individuals.

This fits what we know about panda communication. Adults are solitary and avoid each other most of the year, and San Diego Zoo Wildlife Alliance notes each panda's markings are slightly different from any other panda's.

Other ideas you may read

Before and alongside the 2017 study, scientists proposed several explanations, which the Smithsonian summarises:

• Camouflage in bamboo and snow: a still panda in dense bamboo or among snowy rocks is surprisingly hard to see. The 2017 study refined this idea rather than replacing it.
• Standing out to other pandas: bold contrast might help pandas find each other to mate, or spot each other from a distance in order to avoid contact.
• Temperature control: black absorbs heat and white reflects it, which could help keep body temperature even.

One objection to camouflage is that adult giant pandas have few natural predators. But cubs and young pandas are taken by animals such as golden cats, yellow throated martens and dholes, and long ago tigers and leopards also preyed on panda cubs, so hiding may still matter, especially for the young.

What we can say with confidence

• The pattern is not random: different body regions likely serve different purposes.
• The best tested explanation is camouflage for the body plus communication for the head.
• No single theory has been proven, so be wary of any source that presents one as settled fact.

A note on red pandas

The red panda's russet coat has a simpler explanation offered by San Diego Zoo Wildlife Alliance: it blends in with the reddish moss and white lichen that cover tree trunks in its forests, and the pale face mask breaks up its outline. See red panda facts.
