Przewalski's Wild Horse, also called the Dzungarian Wild Horse, from the steppes (plains) of Mongolia/Central Asia
and China is the only remaining truly wild horse.
It has never been domesticated. It became extinct in the wild in the late 1960s but in the early 2000s it has been reintroduced
from captive-bred Przewalski Horses to two nature reserves in Mongolia and to China. It remains endangered.
The horse is also called the Mongolian Tarpan. All have a similar coat colouring, thick necks and are not much taller than a pony
(about 1.5 metres/13 hands at the shoulder).
They live in herds of females with a lead stallion and separate bachelor herds of males. Przewalski was a Russian explorer.
Other "wild" horses such as the herds of Mustang in America are feral, descended from domestic stock.
