Sighting of Brown & White Panda

It is unfortunate that the new sighting of a brown and white panda is now being presented in some sort of genetic crisis framework without the encounter merely being examined without an editorial context. But such is this day and age, when the media decides to deliver the news less than straightforwardly.

The first reports of finding the cub surfaced late last year, in November 2009.

“This is the fifth time Chinese officials have observed pandas in such a rare color. The first one called ‘Dandan’ was spotted in 1985. It was also found in Foping. She later gave birth to three normal pandas but none of them survived,” noted the Digital Journal.

Here’s the way this breaking new sighting and story are being reported today in Indian newspapers and the Indian edition of a South African paper:

The recent sighting of an extremely rare giant panda with brown and white fur is raising fears that the species may be suffering from inbreeding. 

In November 2009, a staff member at the Foping Nature Reserve in China’s Qinling Mountains – one of the panda’s last remaining strongholds – spotted a panda with the unusual colouring. 

It was estimated to weigh around 2 kilograms, which would suggest it was less than 2 months old at the time. 

This is only the seventh such animal spotted in the region over the past 25 years, Tiejun Wang, a spatial ecologist in the Department of Natural Resources at the University of Twente in Enschede, the Netherlands, told Nature News. 

But the explanation for this unusual variety remains a mystery. 

“It’s time we had a debate about what is causing this because it could be telling us something very important,” said Wang. 

Wang and his Twente colleague Andrew Skidmore are concerned that the brown-and-white form indicates that breeding between closely related pandas is becoming more common.

Each panda has two versions, or alleles, of each of its genes, one inherited from its mother and one from its father. 

Wang suggested that the Qinling pandas carry a dominant gene for black fur and a recessive gene for brown fur. 

This means that pandas with brown-and-white fur are only possible when they inherit the recessive brown gene from both mother and father. 

The chances that both parents have the brown allele are ordinarily very low, suggested Wang. 

But the coincidence would be much more likely if the pandas were closely related.

“The habitat in the Qinling Mountains is seriously fragmented and the population density is very high,” said Wang. 

“The brown pandas could be an indication of local inbreeding,” he added. 

Conservationists worry about such inbreeding because it means that more animals rely on the same set of genetic defences to overcome environmental threats, increasing their risk of extinction. 

According to Wang, brown-and-white pandas have only been seen in the Qinling population, one of five mountain regions where pandas still live in the wild. 

Qinling is home to around 300 animals, roughly one-sixth of the total panda population in the wild. 

The first recorded brown-and-white panda – a female called Dan-Dan – was discovered in 1985. 

She was taken into captivity, mated with a black-and-white animal and gave birth to a normal black-and-white male. 

A few years later, another brown-and-white panda was seen in the wild, together with its black-and-white mother. 

“These anecdotal observations strongly suggest the presence of a recessive gene or genes,” said Wang.

What at the time was the world’s only brown-and-white panda died suddenly on November 23, 2006, at a zoo in northwest China. It was 17 years old and named Qin Qin (shown below).


Loren Coleman About Loren Coleman
Loren Coleman is one of the world’s leading cryptozoologists, some say “the” leading living cryptozoologist. Certainly, he is acknowledged as the current living American researcher and writer who has most popularized cryptozoology in the late 20th and early 21st centuries. Starting his fieldwork and investigations in 1960, after traveling and trekking extensively in pursuit of cryptozoological mysteries, Coleman began writing to share his experiences in 1969. An honorary member of Ivan T. Sanderson’s Society for the Investigation of the Unexplained in the 1970s, Coleman has been bestowed with similar honorary memberships of the North Idaho College Cryptozoology Club in 1983, and in subsequent years, that of the British Columbia Scientific Cryptozoology Club, CryptoSafari International, and other international organizations. He was also a Life Member and Benefactor of the International Society of Cryptozoology (now-defunct). Loren Coleman’s daily blog, as a member of the Cryptomundo Team, served as an ongoing avenue of communication for the ever-growing body of cryptozoo news from 2005 through 2013. He returned as an infrequent contributor beginning Halloween week of 2015. Coleman is the founder in 2003, and current director of the International Cryptozoology Museum in Portland, Maine.
