Lesser Kudu

Male Lesser Kudu and Calf
at the San Diego Zoo
As you could probably guess, the Lesser Kudu is a smaller species of antelope when compared to the very large Greater Kudu. But like their larger relative, they too have striped bodies and large, spiraling horns that can grow up to 3ft long!

Lesser Kudu are most active during the nighttime hours, and they are relatively shy critters. When startled they give out a barking sound, and can bound away quickly if needed. They are very fast (unlike the slow Greater Kudu) and are also excellent jumpers. There have been reports of leaps as high as 2m!

Because of their shyness, Lesser Kudu are difficult to hunt, and so their population has remained relatively safe from hunting, though poaching does exist in some areas. Even more unfortunate is that the species was extremely susceptible to Rinderpest, a virus that spread across several ungulate species until the early 2000s. The population is currently rebounding, but is listed as Near Threatened by the IUCN.

Sambar

Rusa unicolor
Meet the Sambar, one of the most widely spread Deer species in the world... and also one of the most confusing. Sambar can be found throughout South and Southeast Asia, and they have been introduced into the United States, Australia, and New Zealand. However, they vary greatly in size depending on their specific location. This has led to a lot of taxonomic confusion, and currently you might see them refereed to as both Rusa unicolor and Cervus unicolor.

Sambar can grow to some pretty huge sizes. Males have been recorded at over 600lbs! (That is more than double the average weight of the American White-Tailed Deer, for reference) Their antlers can also grow up to a meter long!

Like many Deer, Sambar are crepuscular, meaning that they are most active during dawn and dusk. They are typically solitary, though sometimes small groups of females and their young will forage together. Males live alone, and form aggressively defended territories during the breeding season.

Sambar have adapted very well to different habitat types, and can be found in all types of forested areas, from the very wet to the very dry. The habitat variety has also allowed them to consumes many different types of vegetation. Unfortunately, their adaptability has not kept them off of the Red List. They are currently ranked under "Vulnerable," due to hunting and habitat loss through many countries in their large range.

IUCN Status : Vulnerable
Location : South and Southeast Asia
Size : Length around 80in (2m), Average weight up to 400lbs (180kg)

Dzo

Dzo
Dzo is the Tibetan name for hybrid creatures that are the cross between Yaks and domesticated Cattle. The name technically refers to only the male crosses (females are reffered to as Dzomo), but for the sake of ease we'll use Dzo today for a general term.

Dzo are used as pack animals in Tibet and other mountainous regions because they can survive at high elevations as well as Yaks do, but have more strength and size due to the Cattle ancestry. In general, these hybrids have the faces of Cattle, but the shaggy coats of Yaks.

As with many hybrids, a downside to the Dzo is that the males are sterile. Females are not always sterile though, which means that the animals can be bred back to other Cattle and Yaks, creating 3/4 crosses. It is speculated that many supposed purebred Yaks and Cattle actually have genes from the other species, due to this ability to back-cross.

Pudu

Pudu puda
There are two species of Pudu in the world, the Northern and the Southern. Both are found in South America, appropriately hanging out int he northern and southern stretches of the Andes, respectively. They also (in my opinion) have some of the cutest babies in the entire animal kingdom. Just watch the video if you don't believe me.

The Northern Pudu is the smallest species of deer in the entire world, and the Southern is only a hair bit larger. They have stocky bodies and skinny little legs, and the main difference between males and females is the presence of antlers in the former.

Not much is known about Pudu behavior in the wild because they are both solitary and secretive. They come together only during rut, and the female gives birth to a single fawn that she raises alone. Fawns wean after 2 months, are full grown by 3, and are sexually mature by 8. However, they often stay with their mothers for 8-12 months before leaving and becoming fully independent.

Pudu are active during both the night and day time, and they forage for food along a network of trails and pathways that they create through frequent use. They mark these territories using scent glands. Sometimes Pudu are simply too small to reach their meals, forcing them to stand up on their hind legs to feed.

Both species of Pudu are listed as Vulnerable. This is due to hunting and habitat loss. Captive breeding programs have been set up, and there plans to reintroduce them to the wild.

Baird's Tapir

Tapirs are pretty sweet animals. For one, they look completely unlike just about any other thing you've ever seen... except maybe pigs. But here is the kicker- Tapirs are actually most closely related to Horses and Rhinos!
Tapirus bairdii

There are four species of Tapir, including the Bairds, and they can be found in both South AMerica and South East Asia. Their family, Tapiridae is one of only three living families in the entire Perissodactyla order; another dozen or so are now completely extinct. It's crazy to think that of all the Ungulates in the world, only Tapirs, Rhinos, and Horses remain to represent 55 million years of evolution!

Baird's Tapirs can be found in South and Central America, and are named for naturalism Spencer Fullerton Baird who described them in 1843. They are the largest of the three American Tapirs, and have dark coats with distinctive cream colored markings on the cheeks and neck. Like all Tapirs, they have an extended snout and upper lip that helps them the forage and feel around for food. You can always tell where a Tapir has been because they forage along Zig-Zagged paths of their own creation.

Despite their size, Baird's Tapirs are surprisingly agile, and are great swimmers, divers, and climbers. Their large size makes it difficult for them to dissipate heat, so they typically live around water for easy wallowing on a hot day. 

Sadly, Baird's Tapirs are Endangered, and only around 5,500 remain in the wild. Habitat loss has been their biggest threat, as forested areas continue to be torn down. They are currently part of a Species Survival Plan, and studbook is being kept for captive breeding purposes.

Pyrenean Ibex

Capra pyrenaica pyrenaica
The Pyrenean Ibex is an extinct subspecies of Spanish Ibex. No one is really sure why they went extinct, though there are a number of different hypotheses floating around, including the inability to compete with livestock and other species, hunting, and disease.

The last Pyrenean Ibex died only a decade ago. Efforts were made before that to try and place individuals in captivity, or to even crossbreed them with other subspecies, but these actions failed. The last male died in 1993, and the last female, a 13 year old named Celia, died in 2000 after being crushed by a tree.

Luckily, tissue samples were collected from Celia before her death, and using those cells scientists worked to clone the Ibex back into existence. Efforts in 2003 failed, and no infants were carried to term. However, in 2009 a young Pyrenean Ibex was born, making it the first animal to become un-extinct. Unfortunately the kid died shortly after birth from a lung defect.

The short-lived success of the Pyrenean Ibex cloning program demonstrates the possibilities that exist for preserving and reviving rare and extinct species. While cloning Woolly Mammoths is still a dream, there are several agencies that are preserving samples from the world's endangered species, including the Frozen Ark Project.

Chamois

Ah, the Chamois, one of my favorite quadrupeds. How could one not be smitten with their cute little backwards "J" horns?

Rupicapra rupicapra
Chamois (pronounced Sham-Wah!) are antelope-like goats that can be found throughout Europe. In fact, there are more than half a dozen location-based subspecies, all of which live in mountainous areas. They inhabit ranges from the Alps in France, all the way over in the Caucasians and Carpathians. They have also been introduced to New Zealand. It is unsurprising that, due to their mountainous lifestyle, they have developed great speed and agility over the steep terrain.

Female Chamois and their young live in small groups, while the adult males are solitary and only interact with others during the breeding season. Males will fight fiercely for the right to breed, and will drive away the young males from the family groups, occasionally killing them!

Interestingly, Chamois are not hunted for their meat, as many other ungulates are. Rather, their skin is very sought after, and produces a very soft, absorbent, and non-abrasive. This cloth is often spelled as "Chamois," but is pronounced like "Shammy." Chamois are protected in many countries, but hunted is still allowed in restricted numbers.

Giant Forest Hog

Hylochoerus meinertzhageni
As a species, the Giant Forest Hog of Central Africa is considered to be the largest pig in the entire world. Its only rivals for this title are a handful of Wild Boar subspecies, but even if there is a bigger hog out there somewhere, a body length of nearly 7ft is nothing to sneeze at! (There are actually three different subspecies of the Forest Hogs themselves, with the easternmost being the largest.)

Giant Forest Hogs only live in a handful of African countries, and require humid, densely vegetated habitats. Because of their forest swelling nature, they were not first officially described until 1904, and even now they aren't especially well studied.

The Hogs live in family groups called "sounders" that normally contain one adult males, a handful of females, and their offspring.   Males will fight for breeding rights, charging at each other and ramming their heads together. These fights are occasionally fatal for one or even both parties. Though they do breed year round, most births take place around the rainy season.

Giant Forest Hogs are nocturnal and typically herbivorous-- they feed on different grasses and sedges, and will sometimes take eggs and carrion as well. And even though these Hogs are huge, they still have predators, especially the young ones. Hyenas and Jaguars are their biggest threats.

Kouprey

Bos sauveli (the only captive Kouprey)
Meet the Kouprey, one of the rarest hoofed mammals still alive on our planet-- in fact, it may actually extinct. These large bovines are close relatives  to the Guar and the extinct Aurochs, and could be found in only a very tiny range that includes parts of Cambodia, Laos, Thailand, and Vietnam.

Koupreys live in partially forested areas, where they live in small herds and feed on grasses during the night time. (It is believed they may have been diurnal once, but they adapted to avoid human contact). They have long, narrow bodies, very long legs, and have small humps on their back. Males and females can be told apart by their size, their horns, and their necks. Males have larger bodies and much larger horns that branch upwards. They also have dewlaps on their necks. Females are smaller, have shorter curved horns, and no dewlap.

The Kouprey was only first discovered in 1937, and the only captive specimen was taken that same year. There have been no official sightings since 1988, though tracks have been found and bones have turned up. If they are still out there, there are probably less than 50 left. Koupreys are protected in all countries of their range, and were named the national animal of Cambodia in the 1960s. There are no captive Koupreys currently, so the wild bunch is all we have left.

Bharal

Pseudois nayaur
The Bharal is one of those animals that goes by many different common names. Nabo, Naur, and Himalayan Blue Sheep are all some of the different monikers given to the species. Why so many names? Well, the Bharal lives in Central and East Asia, so different countries with different languages refer to the animal in different ways.

Bharal live in the Himalaya Mountains, as well as in other mountainous regions of China. They can be found at altitudes of between 10,000 and 18,000ft. They graze on the mountain slopes, and their grey coats give them excellent camouflage against predators. If they feel threatened, the Bharal stand perfectly still, blending in with the rocks. If that defensive tactic doesn't work, they can scamper up the cliffs with their sure-footed hooves before trying to blend in again. Of course, they can't always escape from predators. They make up a huge portion of the Snow Leopards' diet, and it is estimated that the Leopards consume between 11% and 24% of the Bharal population every year.

The rutting season lasts from November to January, and during that time males will chase and fight each other for the right to mate with the females. The calves are born 5-6 months later. Both male and female Bharal have horns, but those of the male larger.

It is believed that the Bharal are common in their range, which is why they are listed as being of Least Concern. It is, however, difficult to monitor their population due to their remote habitat and high elevation lifestyle. They do occur in several National Parks.

Tibetan Antelope

Pantholops hodgsonii
Meet the Tibetan Antelope, or Chiru, a endangered ungulate that has been on a free-falling population decline over the past century.

Around 1900, it was estimated that there were over a million of the Antelope roaming about the Tibetan Plateau. Today, estimates are around 75,000 and falling. What has caused this species to decline in such a way? In short, habitat loss, competition from livestock, and shahtoosh.

Shahtoosh is the fine, soft wool that is unique to the Tibetan Antelope (it can be identified by the courser guard hairs in the fiber). Though the Antelope does don't need to die for the wool to be taken, poachers kill them anyway. Even though the animals are protected, the poaching continues and the population declines year after year.

The Tibetan Antelope is a shy animal, and it is (rightfully) wary of humans and other potential predators. They live in herds and are constantly on alert for danger, even digging shallow depressions in the ground when resting so that they are difficult to see. During the mating season males form harems with up to 20 females. They will defend the females, getting into fights with other males that can sometimes be fatal (due to their sharp horns that can grow 2ft long).

IUCN Status : Endangered

Pygora Goat

Pygora Doe
New breeds of domesticated animal are being created created all the time, and today's animal is one that is relatively recent. The Pygora Goat has only had an official association since 1987, and has been in existence only a few years longer than that. That makes them quite young for a breed, especially when compared to the Angora goats that they are derived from, which have existed for thousands of years.

Pygora Goats are a breed created from crossing small Pygmy Goats with the larger Angora Goats. They have the fine goats of the latter, with the compact size of the former. They were first bred by Katherine Jorgensen in Oregon, and the breed has since spread from there. A registered Pygora Goat cannot be more than 75% Angora or 75% Pygmy.

Three distinct fleece types come from the Pygora Goats-- a soft cashmere-like fleece (Type C), a longer, denser Mohair-like fleece (Type C), and a combination of the two (Type B). Fleeces of all types can be used for spinning and knitting, and they produce very soft, fine goods. Pygora Goats do also produce milk, up to a quart a day.

Sivatherium

Sivatherium
Today there are only two living members of the Giraffe family-- the Giraffe itself, and the mysterious mountain-dwelling Okapi. But there were other Giraffes in the past, even as recently as 8,000 years ago!

Today's animal, Sivatherium, is one of those ancient Giraffes. Members of this genus (meaning "Shiva's Beast") lived in Africa and South Asia between 5 million 8,000 years ago. They had bodies similar to Okapis, but where taller and more heavily built. They also had huge, moose-like horns, along with having the small ossicones that the modern Giraffids have. They had very thick, powerful necks in order to hold up those heavy skulls.

One really cool thing that I learned was that human-drawn pictures of the Sivatherium have been found in the Sahara. This means that the animals were quite recent, but it also may unfortunately suggest that hunting was a major cause of their extinction (like many other megafauna of the time).

White-tailed Deer

Odocoileus virginianus (Bucks)
It's that time of year again-- deer season. I live in a state where Deer hunting is a norm and a common topic of conversation  and was actually surprised that I hadn't covered White-tailed Deer on this blog in the past!

The White-tailed Deer is well known throughout North and Central America, and they have even been introduced to parts of Europe and New Zealand. They are one of the most widely distributed mammals in the Americas, and it is no surprise that there are around three dozen different recognized subspecies. They are incredibly adaptable, and live in a huge range of habitats. Grasslands, woodlands, subtropical forests, scrublands, and even suburban neighborhoods all play host to these Deer.

Doe
White-tailed Deer are named for the undersides of their tails, which they raise when alarmed. Those tails communicate danger to one another, but is not their only form of communication. The Deer also produce a variety of sounds (Does and their Fawns bleat to find each other), and mark their territory using scent glands.

White-tailed Deer vary in size, depending on that territory and location. The Key West subspecies is the smallest (weighing around 80lbs), while Bucks in the northern United States and Canada can reach near 300lbs. Bucks are larger than Does, and also are the only sex to sport antlers, which are shed and regrown each year after the rutting season.

Rut takes place in the late fall, and during that times males will compete against one another for breeding rights. A Buck may reproduce with multiple Does each season, and has nothing more to do with the female or her eventual offspring after copulation. Does can have up to three fawns at a time, and they hide their small, spotted offspring in the undergrowth while they go off to feed (mothers of multiples will hide each fawn separately). The young deer are weaned by the end of summer, but will often hang around with mom for another year or two.
Fawn

Because White-tailed Deer live in so many places, they are able to eat many different kinds of plant life. Leaves, grasses, acorns, cacti, fruits, and mushrooms are all consumed by the species. They can also cause problems in farms, orchards, and gardens when they decide to go after corn and other crops.

Overall, White-tailed Deer are listed as being of Least Concern, though some of the subspecies (like the aforementioned Key West variety) are listed separately with their own conservation classification.

Chinese Goral

Central Chinese Goral at the LA Zoo
While walking through the Los Angeles Zoo I was intrigued by the use of space. It's in a very hilly area, but instead of just having empty land, they used those slopes for the enclosures of animals that are right at home on them.

Such was the case with the Chinese Goral, a small goat-like antelope native to the steep, rocky areas of East Asia. Their typical elevation is 3,000-8,000ft, and they have been found in places much, much higher! Naturally, they are very swift and agile over this rough terrain, and are able to use their sure-footedness to escape from predators. As adults, Chinese Gorals have virtually no predators aside from humans.

Chinese Gorals live in small groups year round, and females give birth to one or two kids each May or June. Both the males and females have horns. When it comes to food, they are typically browsers, but they will also consume grasses and other plant materials that are available.

Western Black Rhinoceros

Diceros bicornis longipes
Sad news has been spreading around the animal world this week. The Western Black Rhinoceros, a subspecies of the Black Rhinoceros, has been officially declared extinct.

The population has been on the decline for over a century, due to poaching and lack of government conservation effort. Some conservation measures were put into place decades ago, but they eventually disappeared, along with the Rhino numbers. But 2000 it was estimated that only 10 survived.

The Western Black Rhino could soon be joined by two other Rhinoceros species that are also on the brink of extinction. Illegal poaching has long brought tragedy to these large mammals.

African Wild Ass

Today we're going to learn all about the ancestor to the modern Donkey: the African Wild Ass. These members of the Equus genus were domesticated 6,000 years ago, and while Donkeys can now be found worldwide, their wild relatives have drastically dwindled in number.

Somali Wild Ass mare and foal in captivity
Though they were once found throughout the northern parts of the continent, African Wild Asses are now found only in scattered parts of Ethiopia, Somalia, Eritrea, and Djibouti. They are regionally extinct elsewhere. The climate in these areas is rocky and arid, and the Asses have evolved to survive in dry climates. They can live through water loss that amounts to 30% of their overall body weight, and can rapidly gain those fluids back when water is available. African Wild Asses are most active during dawn and dusk, and they remain in the shade during the hottest parts of the day.

The Asses live in very loose herds that can number up to 50 individuals. The only strong attachments are between mothers and foals; the rest of the herd comes and goes based on the available supply of food and water. Adult males often hold on to large territories near water sources, and mate with females that come in to that range. The males actually mark their territory using dung heaps, which are excellent visual markers in flat landscapes.

The African Wild Ass in general, and two of its subspecies, the Somali and Nubian Wild Asses, are all listed as Critically Endangered. The animals have been hunted for food, and have been crossbreeding with domestic Donkeys for several millennia. They are also forced to compete for food against livestock. As a result of these threats there are only a few hundred left in the wild.

Kiang

Equus kiang
The Kiang is the largest species of Wild Ass in the world, and can be found in the Tibetan Plateau where it lives in the mountainous grassland steppes and meadows. There are three location-based subspecies, with the Eastern Kiang being the largest of the group.

Kiangs stand at around 13.5 hands, which makes them about the size of a large pony. (Horses tend to be designated as Equines over 14.2 hands). Despite this, they are still the largest Wild Asses, standing over 6in taller than their smallest relative- the Somali Wild Ass. They have coats that change with the season-- darker and shaggier in winter, and sleeker and more chestnut-colored in the summer. During all times of the year they have pale underparts and a thick, dark brown dorsal stripe.

Kiangs live in herds that can grow to incredibly large sizes-- up to 500 individuals! These groups are typically led by a older female, and they travel in tight, cohesive groups while searching for food. The breeding season takes place in August and September, and at that time males will fight each other over breeding rights, and will fiercely guard their females. Gestation lasts about a year, and females will breed again not long after giving birth.

In nature, the Kiang has only one predator-- the wolf. Humans have long hunted them as well, using the Asses for their meat and skin. This hunted as reduced the overall range of the Kiang, but the population size is large enough that it is listed as being of Least Concern for the time being. Additional conservation concerns include habitat loss and competition from livestock.

Banteng

Banteng Cow and Calf
Banteng are wild cattle that can be found in South and Southeast Asia. They have even been domesticated in some parts of their range, and it is estimated that there are around 1.5million domesticated individuals in the world, as compared to only a few thousand of their wild counterpart. In their domestic form, they are often referred to as Bali Cattle.

Banteng Bull
Though there are many Banteng in captivity, their wild populations are dwindling, and the species is considered to be Endangered. Hunting, habitat loss, and interbreeding with Cattle have caused the population to decline, and they are becoming regionally extinct.

One neat little tidbit about the Banteng involves their coat coloration. Males and females are sexually dimorphic; though they are both born with reddish coats, over time the females will stay red and develop white stockings, while the males' coats will darken to an almost black color.

Another even more amazing fact is that the Banteng is the second endangered species to ever be cloned. A couple dozen embryos were implanted into female Cattle in 2003. Two calves made it through the entire pregnancy and were delivered by C-Section. The ability to clone endangered, and possibly extinct species presents new ways of maintaining the planet's biodiversity, though it is also important to maintain genetic diversity within the species as well.

Bohor Reedbuck

Bohor Reedbuck
On first glance, the Bohor Reedbuck isn't a flashy antelope. They have short horns, a small to medium build, and sandy, patternless coats. But wait till you hear them and watch them move!

Like a few other species of small antelope, the Bohor Reedbuck likes to hide from predators in tall reeds and grasses. The lack of visibility caused by these tall plants has led the species to create an entire system of shrill screams and whistles in order to communicate. These sounds are used to warn against danger and to mark territory (they do not scent mark). They also posses the ability to perform amazing jumps and leaps which vary in height and length.

You will find the Bohor Reedbuck in Central Africa, living in grassland and wetland areas. They have flexible social groups-- some live alone, other in small groups, and others still in much larger ones (though the large herds usually tend to happen during particularly dry seasons). The Bohor Reedbucks are nocturnal, spending their nights foraging for food. During those aforementioned dry seasons, they will forage well into the daytime as well, in order to get their required sustenance.

There is no specific breeding season, though rainy seasons are more popular. Only one calf is born at a time, and like their parents, they spend a good deal of time in hiding. Newborn calves will stay hidden and secluded for up to 8 weeks.
