Pallas’s Squirrel – Hong Kong Wildlife | 赤腹松鼠 – 香港野生動物

Squirrels are everywhere in the world, with the exception of Antarctica. These rodents can even be found in the Arctic Circle. But did you know that, like Australia, there were no squirrels in Hong Kong originally? They were introduced.

There are 200 species in the squirrel family (Sciuridae) – Chipmunks, marmots, groundhogs, flying squirrels, prairie dogs, just to name a few. But there is only this species that was introduced to Hong Kong – The Pallas’s squirrel (Callosciurus erythraeus) a.k.a. Red-bellied tree squirrel.

This species has a wide distribution throughout most of southeastern Asia from India, Bhutan, Myanmar, to Vietnam, Cambodia, Laos, Thailand, Malaysia, Taiwan, and southern and eastern China, including Hainan, but just not Hong Kong.

It is the only species of squirrel found in Hong Kong. But there are at least 2 subspecies found in here. They are quite clearly apart from each other – C. e. thai is found on the Hong Kong Island such as Pokfulam and Tai Tam. C. e. styani is found in the New Territories such as Tai Po Kau, Shing Mun and Tai Lam.

The Pallas’s squirrel is also known as the Red-bellied tree squirrel. But do not be confused with the Red-bellied squirrel (Rubrisciurus rubriventer) which is another species of Sulawesi, Indonesia.
