Reintroduction efforts are also under way in China, Kazakhstan and Mongolia. The population was estimated to consist of about 2, horses in These horses are very social animals and can be affectionate with one another.
One example is their grooming ritual. Two mares will stand side by side and head to tail. One mare begins by working her way down the back of her partner, nibbling along the back and then to the hind legs. They may pair with a regular grooming partner or any available nibbler. This activity not only keeps the horses clean, but reinforces the social bond.
When interbred, the offspring of a domestic horse and a P-horse has 65 chromosomes and is fertile. The Japanese red-crowned crane is the second- rarest crane species with a total population in the wild of approximately 2, birds. It is illegal to hunt them in all nations where they normally occur As a private nonprofit corporation, Fossil Rim does not receive national or state government support.

But we're getting ahead of ourselves. Przewalski is pronounced shuh-VAL-skee. But you can call it a "P-horse" and most conservationists, zoologists, and zoo keepers and curators will know what you're talking about. Okay, so Przewalski or Przhevalsky?
misptejusi.tk At one time it was thought that the Przewalski horse was first "discovered" by the Russian explorer Colonel Nikolai Przhevalsky, who lived from to It turns out that it was actually discovered and described earlier, but the name stuck. For some reason - and I'm not quite certain why - the Polish spelling became associated with the animal, rather than the Russian spelling.
It was actually in the 15th century that the P-horse was first sighted by a European. Mongolians, presumably, were quite familiar with the Przewalski's horse prior to Schiltberger's visit, but they may have called it the tahki. Other acceptable names are: Asian wild horse, Przewalski's wild horse, and Mongolian wild horse. There was a time when it was called a "tarpan," but pretty much everybody agrees that it's not a tarpan. What is a P-horse? Everybody might agree that they're not tarpans, but that's about where the agreement ends.
It is clear that the Przewalski's horse is a wild, undomesticated horse. In fact, it's the only surviving species of wild horse. Other "wild" horses, like the American mustang, are actually descended from feral domesticated horses who escaped from their herds and adapted to life outside of direct human influence. Much like their equid cousins, the zebras and African wild asses, Przewalski's horses have never been successfully domesticated.
While there are those who would argue that all domestic horses Equus caballus are descended from Przewalski's horses Equus przewalskii , recent genetic evidence suggests otherwise. In , a group of researchers used a powerful sequencing technique to determine that P-horses form their own clade, separate from the lineage that includes domestic horses.
The consensus is that both domestic and Przewalski's horses are derived from a common ancestor, similar to the way in which humans and chimpanzees share a common ancestor, rather than either species being derived from the other. Viable breeding. Usually, species that have a different number of chromosomes can't breed and create viable offspring.
For example, domestic horses have 64 pairs of chromosomes and donkeys have When they breed and give birth to a mule, with 63 chromosome pairs, it is usually sterile. The Przewalski's horse has 66 chromosomes, the most of any equid species. When a P-horse and a domestic horse breed, their offspring are born with 65 chromosomes. Surprisingly, those offspring are usually viable. Still, the P-horse and the domestic horse are usually considered separate species.
The fall of the P-horse. The Przewalski's horse became well known to Western science only in when Przhevalsky described it. By , a German merchant named Carl Hagenbeck had captured most of them. Hagenbeck was a seller of exotic animals, providing critters for zoos throughout Europe and for P. His legacy for the zoo world is mixed - he was among the first to advocate for more naturalistic enclosures, for example - but the Przewalski's horse undoubtedly suffered. By the time Hagenbeck died in , most of the world's P-horses lived in captivity.

But it isn't all his fault. The P-horse was already suffering from over-hunting before Hagenbeck got his hands on them, and the few remaining wild herds continued to suffer from habitat loss and from a handful of particularly harsh winters in the mids.

In , there were just 31 remaining P-horses in the world, in just two zoos, in Munich and in Prague. By the end of the s, only 12 individuals remained. A conservation success story. All P-horses still alive today are descended from nine of those 31 captive horses in Since then, the Zoological Society of London has worked together with teams of Mongolian researchers to conserve the species.
The captive breeding programs were so successful that in just fifty years the species rebounded to over individuals by the early s.
