The Mongolian subspecies of the Onager has been recently listed as Vulnerable since the 1990s saw a massive decline in their numbers.  The population is failing because of direct human actions, like poaching and competition from grazing livestock, since 1953 the Mongolian Wild Ass has been fully protected in Mongolia, and it is listed in the CITES in appendix I and II.  Even with full protection poaching for meat is on the rise as it is a cheap alternative to domesticated animal meat.  One of the other Onagers is the Indian Wild Ass, or khur, and it is vanishing in parts of India. At one point the population may have dipped below one thousand, but recent conservation efforts have helped bring them back from being close to the brink.

Hinnies are difficult to produce because of the chromosomal difference from the mother is 62 and the father is 64 – which makes it more difficult to produce.  It is easier with a mule because the male father has 62 while the mother has 64, and it is usually more viable.  There have been no recorded cases of any fertile male hinnies, however there has been one single documented case of a fertile female hinny. Another reason that hinnies are so rare to find and conversely hard to produce is that the stallion male (the sire) is picky, and will often times not wish to mate with a donkey, and the donkey mare (the dam) is just as picky, if not more so, compounding the problem.

Zebrony belongs to this family. It is the result of the copulation between a zebra and a pony. Another term given to it is zony. When a male zebra (stallion) and a female pony (mare) mate, their offspring is referred to as a zony. People also call it by different names such as ponibra and zeny. Obviously the names are derived from the names of their parents combined together (zebra/pony).

The physical attributes of a zebrony follow the characteristics like that of a pony only with distinguishable stripes like that of a zebra. However, the stripping is concentrated mostly on the rear and leg part depending on the zebra specie. Some zebronies may have the stripping scattered on different parts of the body particularly.

Typically, the height of a zebrony will not reach 5 feet just like the common pony, which has proportionately short legs but are considerable strong. The mane and tail are significantly thick and the neck is wide. Naturally, these characteristics will depend on the pony breed. Its color, too, will vary depending on breed type.

Zebronies are among the hybrids that are most commonly preferred for practical uses. This is because they are, like many horse breeds, clever and very trainable. However, they are considered to be, at times, stubborn, aloof, temperamental and can be difficult to manipulate. These characteristics are associated to their zebroid quality.

One type of mule or hybrid that has not yet gained so much popularity, and is in fact still unheard of, is the zebrule. The name could have been a combination of the names zebra and mule. However, the animal of this breed is more commonly known or called zenkey (zebra plus donkey).

Zebrule is the offspring of a male zebra (a stallion) and a female donkey (a jenny or jennet). Zebrules have not grown in number yet. The small percentage of this breed can be found in South Africa. One zebrule was reported to have been born in Barbados, Venezuela, christened Alex. Typically, zebrules can be spotted in areas where donkeys and zebras live at a close distance to each other, which proved to be true, since Alex’s inception was because of a zebra and a donkey’s sharing of one common area for a span of time.

Zebrules are rare. The reason why their population has not increased is the fact that zebrules are (mostly) barren. This is ascribable to their discordant chromosome count, which is only 63. The chromosome result is due to the incompatibility of chromosome counts of the parent stallion and jenny. A zebra has 44 chromosomes while a donkey has 62.

Zebrule is also known by the names zonkey, zeedonk, zenkey and zebronkey. Its physical characteristics and traits are equally taken after both parents. Commonly, the stripes of a zebrule can only be seen on the lower part of the body, typically on the hind part and on the legs. Some zebrules, however, have stripping on their belly part. Some, with almost the entire body covered with stripes.

The prominence of its stripes depends on the zebrule’s color. Naturally, when a zebrule has a dark color, the striping will not profoundly show compared with a light brown colored zebrule. A zebrule’s color takes the color or the regnant color gene of the female donkey or jenny.

Zebrules move faster than a common mule or donkey. They are prey animals, too, like the animals of their same specie. However, zebrules are quick to defend themselves when a predator corners them. Their senses are much stronger and they will scurry for safety when they recognize peril. Just like mules and donkeys, zebrules are clever and can be easily trained.

Zebras, horses and donkeys are all part of the Equidae family (animals belonging to the family of horses). Because of this, these three animals can inter-breed, hence the probability for creation of more breeds and new strange names such as zebrule.

A zorse is an animal that is muscular and heavily built. Driven from horse and zebras and base on which species of zebra it is bred, its hybrid can be like a pony or a horse. But it is more likely two to three folds stiffer than a horse. But its animalism, features and temperament are more comparable to zebras. Its mane does not grow long, it stands-up same as a zebra or, more often, drops down same as the horse. With its average height of 13 to 16 hands, zorse is well proportioned. Its resemblance in horse includes its color. May it be black or darker base for its bodily stripes. Zorse stripes are not equally formed than of the zebras. More of its hybrid output is single or double colored face with white legs. With its well-toned muscles, its strength and straight legs, zorse looks brave and hefty.Zorse are also trained like other animals. They can excel in jumping and trailing. Their trainer can be their best friend. They are good followers and are intelligent. Compared to horses, zorse attitude are way better in terms of personality and braveness.

Generally speaking these breeds look a like but when you take a closer look, there are several differences that you could spot. The hinny’s face resembles more of a horse than a mule. Also, the ears of a hinny are rounder and shorter compared to a mule. Aside from that, hinnies are also smaller compared to mules. Also, hinnies have a tail and mane that resembles a horse. Another horse like attribute that hinnies were able to get from their father is the color of their coat. This is due to the fact that in most cases, the color of the coat will be based from the genes of the male parent.

In cases wherein a hinny offspring is created, this offspring is usually sterile. The reason behind this is due to the differences of the chromosomes of the donkey and horse. You can find sixty-two chromosomes in a donkey while there are sixty-four chromosomes for a horse. The result of the cross breed between these two animals provides sixty-three chromosomes for hinnies. Because of having an odd-numbered chromosome, hinnies are regarded to have an incomplete reproductive system.

The Mule deer, also called big-eared deer, lives in the western mountain regions of the North American continent. Its population is spread up from south Alaska in the north, to Mexico in the south and from the pacific coast in the west to North and South Dakota in the east.
In opposite to the mule deer’s cousin the white tailed deer. The mule deer is not a commensal species, but likes it to stay hidden and live an invisible life in areas far away from civilisation.
The colouring of the mule deer is dependent on the season and varies of cold grey till red-brown. It reaches a body length of 170 to 220 cm, a weight from 50 to 160 kg and a shoulder height of 100 to 120 cm. The antlers are not very big, subdivided for this but clear and graceful.

The Mule deer got its name because of its long ears (28 cm), which make him look like a Mule. Hunters also call him “jumping deer”, because Mule deer often jump while fleeing..

Males and females live, e in separate herds, older males, sometimes as loners. The cohesion of these herds is loose and a strict hierarchy is only developed during the mating season.
Mule deer like it to spend the summer in the upper mountain regions and return to their lower residents in winter. There the stronger males assemble smaller groups of females around himself during the rutting season in December with which they mate and from whom they jealously keep every rival away.

The pups occur after a gestation period of 210 days in June and July during the leisurely remigration to the summer residence. At the birth they weigh 2 to 3 kg and carry a spotted fur.
Within the first days they hide in the thicket and are visited by the mother only for suckling.
They then follow her and hook up to the herd. In the first months of their life, many of them become the victim of pumas, coyotes and bobcats.

Because of excessive hunting the mule deer population went back from 10 million down to 300.000 in the beginning of the 20th century. The population increased back to 5 millions but however, stagnates since the 1960’s.

The mule deer is not a hybrid species!

The Zorse (Zebra and horse)

Zorse describes especially the hybrids of a horse and zebra which usually shows a greater similarity to a horse than to a zebra. Zorses have hologram similar stripes which seem to change their form depending on the viewpoint and time of day.

Like the mules and hinnies, as a rule, Zebroids are not capable of reproduction.

The Zebrule

Zebrule is a hybrid between a zebra and a donkey and is also called Zebronkey. The Zebrule is usually sterile. As a wild animal it can be found in areas where Zebras and Wild-donkeys live in very close neighbourhood. Some are known about these hybrids.

Zebrony

A hybrid of a Zebra and a pony, they are as small as a pony, dark fur but still some stripes, just like the Zebra. This tiny animal has still a zebra dominated character.
