"Elk is a type of deer. It has antlers like a deer, a face like a horse, hooves like an ox, and a tail like a donkey. How strange."

"Like other cervids, elk is also a herbivorous mammal. Generally, male elk can weigh up to 200 kilograms, with horns up to 80 centimeters long, and they shed them once a year."

Angular type

The elk's antlers are unique among deer species - when standing, the tips of each branch of the elk's antlers point backward, while the tips of other deer point forward. Female elk have no antlers and are smaller.

Tail

The elk's tail is the longest among the deer. The long tail is used to repel mosquitoes and flies to adapt to life in the swamp environment.

The role of the tail

The tail has functions such as warning, balance, and weapons. All deer have tails, but they differ in length. The shortest one is the roe deer, with only some white hair growing on the tail, like a tail. The longest one is the elk's tail. Like a donkey, the tail is as long as the ankle. Because there are many mosquitoes, flies and gnats in the swamp environment, a long tail can help drive them away and prevent them from being bitten. The elk's tail is much longer than other deer, up to 65 cm, the longest among deer, and has tufts of hair at the end.

hoof

Elk have wide hooves and move briskly and quickly. They often stand, wade, dive and forage in the water, even in the middle of winter.

return

1. Later, most of the elk living abroad died one after another. Only the 18 elk raised by the British Duke of Bedford in the Ubon Temple Zoo in his private villa grew well and multiplied rapidly. By 1967, the number of elk here had increased to more than 400, and they were exported to other countries. To date, the total number of elk in the world is estimated to be over a thousand.

2. In August 1986, with the efforts of the World Wildlife Fund and the Ministry of Forestry of my country, 39 elk selected from seven zoos in the UK returned to their hometown and were sent to Dafeng Elk Nature Reserve for free rein. From then on, the elk ended their wandering and wandering overseas life for more than half a century, and began a new life of returning to their homeland and nature. Today, this group of rare animals are reproducing and thriving on the land of their motherland.

return to homeland

The number of elk living in foreign lands is decreasing due to the deterioration of the ecological environment. At this time, a man appeared who saved the elk from the desperate situation: the 11th Duke of Bedford, a man who loved animals, especially deer. Starting in 1898, he spent a lot of money to buy a total of 18 elk that were originally kept in zoos in Paris, Berlin, Cologne, Antwerp and other zoos. They became the only group of elk that were dying and incense left on the earth. By the end of 1983, there were 1,320 elk in the world, all descendants of the original 18 elk. They are spread throughout Asia, Europe, Africa, the United States, and Australia, but they have not returned to their hometown of China where they have lived for generations.

China is the home of elk. As the motherland becomes stronger and more stable, many Chinese zoologists call for the return of overseas elk. In March 1984, the owner of Ubon Temple, the Marquess of Tavistock, commissioned Ms. Maya Boyd, a zoologist from the University of Oxford in the United Kingdom, to come to China to investigate the situation and select a replay location. Finally, it was decided to donate 20 elk to China and return them to Nanhaizi.
