Vanished for over a century… and then suddenly, it reappeared.
The Western Woolly Flying Squirrel isn’t just another cute, tree-hopping rodent — it’s a living mystery straight out of a wildlife thriller.
First described in 1888, this high-altitude glider seemed to vanish into legend, with scientists declaring it possibly extinct. Then, in 1994, deep in Pakistan’s rugged mountains, it was dramatically rediscovered — alive, massive, and unlike any flying squirrel you’ve seen before.
Imagine an animal almost the size of a house cat, wrapped in thick woolly fur, silently gliding between cliffs under a Himalayan moon. This is no ordinary squirrel. It’s a survivor, a legend, and one of the rarest mammals on Earth… and its story will leave you amazed.

Disappeared for a Century – The Return of the Western Woolly Flying Squirrel
For over a hundred years, it was a ghost in the natural world — a creature so elusive that many believed it had vanished forever. The Western Woolly Flying Squirrel (Eupetaurus cinereus) is one of nature’s most mysterious and remarkable survivors, an animal wrapped in both thick fur and thick mystery.
The Western Woolly Flying Squirrel was first described in 1888 by British zoologist Oldfield Thomas, it was known only from a handful of specimens collected in the Himalayas. And then… silence. For more than a century, no confirmed sightings, no new records. Scientists feared the worst — that it had quietly slipped into extinction.
But in 1994, deep in the rugged, snow-dusted mountains of northern Pakistan, wildlife biologist Dr. Peter Zahler made an astonishing discovery. Against all odds, the woolly flying squirrel was alive — thriving in one of the most inhospitable habitats on Earth. That moment reignited global interest, breathing life into a story many thought had ended long ago.
Thick, woolly, grey-brown fur shields it from the freezing winds of the high Himalayas. A wide patagium, or gliding membrane, stretches between its limbs, allowing it to soar from tree to tree — and, unlike most of its cousins, even from cliff to cliff. By night, it navigates steep rocky slopes and scattered forests, retreating to caves when dawn arrives.
The Western Woolly Flying Squirrel is a giant among flying squirrels — its body stretching up to 60 centimeters (24 inches), with a bushy tail nearly as long, serving as both a counterbalance in flight and a warm blanket in rest.
Its home lies in the remote heights of Gilgit-Baltistan — in the valleys of Astore, Chitral, and Neelum — and, rarely, in parts of India and Afghanistan. Here, at altitudes between 2,400 and 3,800 meters (8,000 to 12,500 feet), it feeds mainly on the needles of cedar and spruce, occasionally nibbling on mosses and lichens that cling to cold stone.
And yet, life here is perilous. Deforestation, human encroachment, and hunting for fur and meat have pushed it to the brink. Climate change, too, is altering the fragile balance of its high-altitude world. The population remains a mystery, but scientists believe it is perilously small and scattered — a species clinging to survival.
Among mountain communities, the woolly flying squirrel is a creature of curiosity and legend, whispered about in stories passed through generations. To conservationists, it is more than that — it is a living emblem of the biodiversity hidden in Earth’s most inaccessible places.
The rediscovery of the Western Woolly Flying Squirrel is a reminder that even in a rapidly changing world, nature holds secrets — and sometimes, second chances.
The story of the woolly flying squirrel is one of survival against the odds, a blend of mystery, resilience, and hope… proof that the rarest creatures can still be found, and still be saved, if we care enough to try.
Western Woolly Flying Squirrel – 10 Fascinating FAQs About This Rare Himalayan Glider
The Western Woolly Flying Squirrel (Eupetaurus cinereus) is one of the world’s most mysterious mammals — a rare, high-altitude species once thought extinct for over 100 years. Rediscovered in 1994, it has captured the interest of wildlife enthusiasts, scientists, and conservationists worldwide. Below are 10 frequently asked questions about this extraordinary creature.
1. What is the Western Woolly Flying Squirrel?
The Western Woolly Flying Squirrel is among the largest and rarest flying squirrels on Earth. Covered in thick, woolly fur, it thrives in some of the most remote mountain regions of Pakistan, India, and Afghanistan. Known for its secretive lifestyle, it remained hidden from science for more than a century until its dramatic rediscovery in 1994.
2. Where is the Western Woolly Flying Squirrel found?
The Western Woolly Flying Squirrel inhabits the Himalayas and Karakoram ranges, primarily in Gilgit-Baltistan, Pakistan — including the Astore Valley, Chitral, and Neelum Valley. Rare sightings have been reported in parts of India and Afghanistan. It prefers rugged, rocky slopes with scattered conifer trees at altitudes of 2,400 to 3,800 meters.
3. Why is it called a “flying” squirrel?
Despite its name, the Western Woolly Flying Squirrel doesn’t actually fly. Instead, it glides through the air using a skin membrane called the patagium. This adaptation allows it to travel from tree to tree or even cliff to cliff, conserving energy while escaping predators or foraging for food.
4. What does the Western Woolly Flying Squirrel eat?
Its diet mainly consists of conifer needles, particularly from cedar and spruce trees. It also consumes mosses and lichens that grow on rocks. These high-fiber foods are perfectly suited for its mountainous environment, where other vegetation is scarce. It is most active at night, foraging under the cover of darkness.
5. How big is the Western Woolly Flying Squirrel?
The Western Woolly Flying Squirrel is one of the largest flying squirrels in the world, measuring up to 60 cm (24 inches) in body length. Its long, bushy tail is almost the same size, helping with balance during gliding and providing warmth during cold Himalayan nights.
6. Why did scientists think it was extinct?
After the first scientific description of Western Woolly Flying Squirrel in 1888, there were no confirmed records for over 100 years. Remote habitats, nocturnal habits, and lack of field studies meant it went undetected. Many assumed it had vanished until Dr. Peter Zahler’s landmark rediscovery in Pakistan’s mountains in 1994.
7. Is the Western Woolly Flying Squirrel endangered?
Yes. The Western Woolly Flying Squirrel is listed as endangered due to habitat loss, hunting, and climate change. Logging of coniferous forests, human encroachment, and hunting for fur and meat have significantly reduced its numbers. With its population small and scattered, urgent conservation action is needed to protect it.
8. How does it survive in such cold, harsh environments?
Its thick, woolly coat is perfect insulation against freezing Himalayan winds. The squirrel also takes shelter in caves and rocky crevices to avoid extreme weather. Its gliding ability lets it travel between distant trees and cliffs without descending to the dangerous forest floor, where predators might be waiting.
9. Does it hold any cultural or folklore significance?
Yes. Among mountain communities, the Western Woolly Flying Squirrel is often surrounded by mystery and curiosity. Its rare sightings and unusual appearance have linked it to local folklore, making it a symbolic creature of the wild, untamed highlands.
10. Why is the rediscovery of Western Woolly Flying Squirrel important?
The rediscovery of the Western Woolly Flying Squirrel proves that species believed extinct can still survive in hidden, undisturbed habitats. It has captured the interest of wildlife enthusiasts, scientists, and conservationists worldwide. It emphasizes the importance of conserving remote ecosystems, which may shelter other unknown or endangered species. This squirrel has become a symbol of hope for global wildlife conservation.
