Paignton zoo in Devon has a baby Dik-Dik

The dik-dik is a small antelope, found in East Africa. I have been lucky enough to encounter them on many occasions, when on safari in Kenya.

They tend to move around in pairs, and the bond is so strong, it is not uncommon for them to follow each other out in front of cars.

A Kirk’s dik-dik in the wild

With a population of almost 1 million, this species is listed as least concern, never-the-less it is of great interest to see it in captivity.

Paignton zoo had a baby dik-dik arrive on new years day, so it will be even smaller than normal.

Rhea species

Greater Rhea

Lesser Rhea

This map shows the range of a number of different subspecies

Found in Eastern South America, it is also known as the America, Common or Grey Rhea. In Portugese it is known as Ema. It is found in grasslands, Savanna or wet grasslands. When fully grown it weighs 20-27kg, and can live to around 10.5 years. It is listed as near threatened with a population of unknown size. Its range in South America is large, covering 6.5 million square km (2.5 million square miles).

Back in the  90s 6-8 individuals escaped from a private zoo in Germany, and this population has grown to around 550 birds.

Also known as the  Darwins rhea. Its found on the Andean plateau as well as Patagonia.

Mostly a herbivore, it will take lizards and animals such as grasshoppers when the opportunity arises. They are listed as least concern and there are two subspecies (see the map to the right). While the main subspecies still has a range of 850,000 square km, and a population that is healthy, both other subspecies (found further north) have populations of only several hundred.

Should either of these species get mentioned in the blog, they will appear below (though it is possible with a short name, the letters may appear in other articles).

As we make contacts which will allow you to see these species in the wild, they will be added below the news carrousel – do get in touch with the form at the top of the home page, we would love to help people fiind you

Reversing extinction: Marwell zoo and the scimitar-horned oryx

Declared extinct in the wild back in 2000, this species is now not only re-established in the wild, but has a big enough population to now only be listed as endangered (down from critically endangered).

Apart from supplying individuals for the reintroduction, Marwell zoo also helped with strategy.

The video below is just 2 minutes long. While it talks about Marwells other work as well, it shows a number of these animals living wild back in Africa.

This has got to become the reason for zoos. What ever else they do, there are many species at risk of extinction in the wild, these need to have enough captive individuals to re-establish wild populations, should the current conservation fail.

Of course, zoos have many other roles, from education, to fostering a love of wildlife in the next generation.

One thing that they should not be, is a curio house- many zoos are far to worried about displaying albino or melanistic individuals. Now while these individuals are fascinating and can be used as ambassadors for the species, their genetic health should be looked after (all white tigers are descended from one female, and closely related individuals are regularly bred togerther to ensure this trait is passed down. Indeed, as a result of this, white tigers are often not of good health.

The majority of zoos are now like Marwell – while like many, it started as the private zoo of wealthy owners it has turned into an important place of conservation and science. Another of their successes, is the cooperative breeding that occurs as standard in current times, across Europe. Regular loaning of animals is essential, so that we can treat all of the zoo animals in Europe as one single population, thereby  making sure that all animals in the system are healthy.

There are many hundreds of zoos across Europe (some claim as many as 2000, though around 1500 is the estimated worldwide number suggesting that this is a rather large exaggeration. It is likely that around half of the worlds zoos are in Europe, and by cooperative breeding, we can make sure that healthy populations remain in captivity, so that should a population be lost from the wild, it can be returned, when the wild situation improves.

Almost all predictions about human population are expected to peak in the coming decades, and then decline after that. If this pattern is followed, it should be expected that we will need to re-establish wilderness in the future. 

Scimitar-horned oryx have been returned to the wild in Tunisia, and Chad and there are plans to return them to the wild in Niger, in the near future.

Extinction was caused by a variety of features, but the primary one was over-hunting. This has virtually been eliminated, after a ban on hunting of this species was put into effect in 2013. Should this species be allowed to fully recover. In 1985, there was a population of at least 500 of this species living in the wild, so it took only 15 years for it to disappear, as such what is clearly essential is a regular assessment on how this species is faring, allowing earlier interventions.

Saving the natural world, may require this kind of success to be a regular feature.

Dominica’s mountain chicken frog is heading to extinction faster than anything recorded before

Once so common that they were cooked as a national food on the island. Yet in just two decades, the animal is one of the rarest in the world, with an estimated population of just 21.

Growing to 20cm long and weighing over 1kg, it was one of Dominica’s apex predators. eating small mammals, snakes and other frogs.

It’s decline is notable, as its calls were formerly something that you heard across the island.

Now, silence from this frog has fallen across most of the island.

Initially, its decline was caused by a fungus, which impacted amphibians skin – important, as many amphibians breathe through there skin, and all breathe through their skin.

The breakout of this fugni led to a decline of 80% in just one year. Known to only occur on one other island (Montserrat), scientists urged strict quarantine measures to stop it arriving, but these warnings failed to have any effect.

A number of these frogs were removed in 2009 as the illness began to spread, and they are housed around the world in various zoos, such as London zoo.

In recent times, a few surviving individuals have been discovered. These appear to be naturally resistant to the chytrid fungus that is at fault.

Unfortunately, shortly after, hurricane Maria hit, and the population declined a further 80%, back into double digits.

Due to the lack of immunity to this fungus, it would appear that zoo individuals that were rescued back in 2009 are all irrelevant. Whether with such a small wild population, it is worth capturing more (it is possible that these new individuals could be bred with already captive individuals, bit this may not retain the immunity).

The remaining wild frogs are found in 2 populations, and neither are found on protected land. As such, the situation could change fast if land use changes would occur.

The conservationists in the wild are still working, but it is thought that there is only 2 years left to save the species from extinction.

3.4.5 Peleinae, Alcelaphinae, Hippotraginae

Subfamilies 3. Peleinae, 4. Alcelaphinae, 5. Hippotraginae

The subfamily 3. Peleinae (one species)

Grey Rhebok

Grey Rhebok

The grey rhebok or grey rhebuck, locally known as the vaalribbok in Afrikaans, is native to South Africa, Lesotho, and Eswatini (Swaziland). The specific name capreolus is Latin for ‘little goat’. Generally confined to the higher areas of Southern Africa, they typically inhabit grassy, montane habitats – for example, sourveld – usually 1,000 metres (3,300 ft) above sea level, and carry a woolly grey coat to insulate them from the cold. They are not strictly limited to this habitat as they can be found in the coastal belt of the Cape, almost at sea level.

The grey rhebok is listed as “Near Threatened”, with a population of between 10,000-18,000

4. Subfamily Alcelaphinae - Sassabies, Hartebeest, Wildebeest (6 species)

Hirola

The HIrola ( also known as the Hunters hartebeest or hunters antelope) is a critically endangered species. It was named by H.C.V Hunter (a big game hunter and zoologist) in 1888. It is the only member of the genus Beatragus, and it currently has 300-500 individuals living in the wild (there are none in captivity).

It is a widely known fact, that should the Hirola be lost from the wild, it will be the last species in its genus, and therefore the first mammal genus to go extinct in Africa in the modern era. Locals have got behind this species, with 17 conservancies protecting much of the area. There are even efforts to make some of this area devoid of predators, so as to help this species bounce back faster.

Hirola

Tsessebbe, other names regularly used include Topi Sasseby and Tiang

Tsessebbee

The Tsessebbe is part of a group of so called species, which are actually subspecies (there are 5 or 6 subspecies recognized

It is closest related to the Bangweulu Tsessebe, Less so, but still very close to the Topi, Korrigum, Coastal Topi and teh Tiang subspecies. Even the Bontebok is very closely related.

  •  Tsessebbes have around 300,000 living wild
  • Korrigum (Senegalese Hartebeest) in 2004, it was numbered 2650, split between 2 national parks. They situation has not improved
  • Topi are doing well with over 100,00
  • Currently, the Tiang still number very high.

Bontebok

Found only in Southern Africa, its range includes South Africa, Lesotho and Namibia

There are 2 subspecies:

  • Bontebok, found around the western cape -2500-3000 (vulnerable IUCN)
  • Blesbok, found in the high-veld. Closely related to the Tsessebe has a population of around 120,000 (Least concern IUCN)
The majority of this is in protected reserves, meaning that the current threat is low and this species should keep growing
Bontebok

Hartebeest

Hartebeest

The Hartebeest – as many as 70 subspecies, local variants and similar have been suggested, however there is only one currently recognized species.

Overall, the species is listed as least concern with a population of around 360,000. The red hartebeest has a population of 130,000, but at the other end the Swaynes hartebeest in Ethiopia is only thought to number 800 in the wild. The Bulbul hartebeast (light blue) is extinct. The Lelwel Hartebeest(green) is considered endangered and has around 70,000 members. The western or Major hartebeest has around 36,000. What is clear, is that if you are travelling to an area where the local hartebeest is struggling, it would be we worth paying to see them, so as to give a value to them

Blue Wildebeest

  • Other names include common wildebeest, white-bearded gnu or brindled gnu.

There has been five subspecies recognized:

 

  • C.t.taurinus (Burchell, 1823), the blue wildebeest, common wildebeest, or brindled gnu Inhabits the dark brown range

  • C. t. johnstoni (Sclater, 1896), the Nyassaland wildebeest, inhabit orange (Tanzania, Mozambique Malawi)
  • C. t. albojubatus (Thomas, 1912), the eastern white-bearded wildebeest, found in the Gold (beside the Yelow)
  • C. t. mearnsi (Heller, 1913), the western white-bearded wildebeest, its range is shown in yellow
  • C. t. cooksoni (Blaine, 1914), Cookson’s wildebeest, is restricted to the Luangwa Valley in Zambia. This is the mighter brown

In addition, the distinctive appearance of a western form, ranging from the Kalahari to central Zambia, suggests that subspecies mattosi (Blaine, 1825) may also prove distinct from subspecies taurinus. The western form can be recognised even at a distance by its upright mane, long beard, and minimal brindling.

There are around 1.5 million of this species living in the wild – so they are not endangered. Having said this, given that 1.3 million (almost 90% of them live in the Serengeti ecosystem), were something to happen, we could be in a very different position..

Blue wildebeest

Black Wildebeest

Black wildebeest

The Black wildebeest is the black wildebeest or white-tailed gnu is one of the two closely related wildebeest species.  It was first described in 1780 by Eberhard August Wilhelm von Zimmermann. It came surprisingly close to extinction, having been hunted as a pest and for its meat and hide.

The current population is now thought to be around 18,000, though 7000 of this is in Namibia (outside their natural range) where they are farmed. Their conservation status is least concern

5. Subfamily Hippotraginae

Addax

The waterbuck  is a large antelope found widely in sub-Saharan Africa.It was first described by Irish naturalist William Ogilby in 1833.

Its 13 subspecies are grouped under two varieties: the common or ellipsiprymnus waterbuck and the defassa waterbuck. The head-and-body length is typically between 177 and 235cm  and the typical height is between 120 and 136cm. In this antelope, males are taller and heavier than females. Males reach roughly 127 cm at the shoulder, while females reach 119cm. Males typically weigh 198–262 kg and females 161–214 kg. Their coat colour varies from brown to grey. The long, spiral horns, present only on males, curve backward, then forward, and are 55–99 cm long. Waterbucks are rather sedentary in nature. As gregarious animals, they may form herds consisting of six to 30 individuals. These groups are either nursery herds with females and their offspring or bachelor herds. Males start showing territorial behaviour from the age of 5 years, but are most dominant from the six to nine. The waterbuck cannot tolerate dehydration in hot weather, and thus inhabits areas close to sources of water. Predominantly a grazer, the waterbuck is mostly found on grassland. In equatorial regions, breeding takes place throughout the year, but births are at their peak in the rainy season. The gestational period lasts 7–8 months, followed by the birth of a single calf.

Waterbucks inhabit scrub and savanna areas along rivers, lakes, and valleys. Due to their requirement for grasslands and water, waterbucks have a sparse ecotone distribution. The IUCN lists the waterbuck as being of least concern. More specifically, the common waterbuck is listed as of least concern. while the defassa waterbuck is near threatened. The population trend for both is downwards, especially that of the defassa, with large populations being eliminated from certain habitats because of poaching and human disturbance.

The common waterbuck is listed as least concern, while the Defassa is listed as near threatened. Only 60% of this subspecies population is in protected areas, so it could get worse, if they are lost.

Sable Antelope

Sable Antelope

The Nyala is a spiral horned species

 found in Southern Africa. The nyala is mainly active in the early morning and the late afternoon. It generally browses during the day if temperatures are 20–30 °C  and during the night in the rainy season. The nyala feeds upon foliage, fruits and grasses, and requires sufficient fresh water. It is a very shy animal, and prefers water holes to the river bank. Not territorial, they are very cautious creatures. They live in single-sex or mixed family groups of up to 10 individuals, but old males live alone. They inhabit thickets within dense and dry savanna woodlands. The main predators of the nyala are lion, leopard and African wild dog, while baboons and raptorial birds prey on juveniles. Males and females are sexually mature at 18 and 11–12 months of age respectively, though they are socially immature until five years old. They have one calf after 7 months of gestation. Its population is stable, with the greatest threat coming from habitat loss as humans expand. There are thought to be 36500 and the population is stable.

Giant Sable

Red Lechwe antelope are found in a band across Africa, including areas of Eastern, Central and Western Africa.

There are 3 subspecies:

  • The western kob, is found in the west
  • The Ugandan Kob is found in sub-Saharan Africa in South Sudan, Uganda and the Democratic Republic of the Congo.
  • The white eared Kob is found in Western Ethiopia and South Sudan (this is one of the main animals in the huge migration within sudan)
None are currently threatened with extinction. Their total population is 50,000-60,000

Impala

Impala

There are currently around 2 million Impala roaming across Africa.  About one quarter of these live in protected areas in Botswana, Kenya, South Africa, Tanzania, Zambia, and Zimbabwe. Around 1000 of the Black faced Impala live in the green area in the west of Africa.

7. Subfamily Antilopinae

Dama Gazelle

The Dama Gazelle is a small antelope, species with a handful of small populations acros central and western north Africa. It lives in the Sahara and the Sahel desert. 

In Niger, the Dama Gazelle has become a national symbol.

There are 3 subspecies, however the Mhorr gazell is extinct in the wild (though zoos have a number) , the dama gazelle is only kept in captivity one zoo and is very rare in the wild. 

The species is critically endangered with only 100-200 left in the wild. Given that this small population is spread over a number of areas. The number of wild semi wild and captive is around 2900, so it is just the need to save the species in the wild which is the current problem.

Schimiter Oryx

Pacific white-sided dolphin

Pacific white-sided dolphin

The Pacific white-sided dolphin, also called the hookfin porpoise, is an active dolphin found in the cool or temperate waters of the North Pacific Ocean.

The Pacific white-sided dolphin was named by Smithsonian mammalogist Theodore Nicholas Gill in 1865. It is morphologically similar to the dusky dolphin, which is found in the South Pacific.[6] Genetic analysis by Frank Cipriano suggests the two species diverged around two million years ago.

Though traditionally placed in the genus Lagenorhynchus. Molecular analyses indicate they are closer to dolphins of the genus Cephalorhynchus, in the Lissodelphininae subfamily, than to both the Atlantic white-sided dolphin and the White-beaked dolphin. It has therefore been proposed to move the Pacific white-sided dolphin to the resurrected genus Sagmatias together with other southern hemisphere species (hourglass dolphin, Dusky dolphin and Peale’s dolphin).  However, there is still some analysis to do, before this move can take place.  White-sided dolphins swim in groups of 10 to 100, and can often be seen bow-riding and doing somersaults. Members form a close-knit group and will often care for a sick or injured dolphin. Animals that live in such large social groups develop ways to keep in touch, with each dolphin identifying itself by a unique name-whistle. Young dolphins communicate with a touch of a flipper as they swim beside adults.

United Nations banned certain types of large fishing nets in 1933, many Pacific white-sided dolphins were killed in drift nets. Some animals are still killed each year by Japanese hunting drives

There are around 100 in dolphinarias in the USA and Japan. They are currently listed as least concern

Below is a list of any articles on the species, and below that a video of it. Under this, I will add any links that might help you see this species in the wild.

African Dwarf crocodile

African dwarf crocodile

The dwarf crocodile (also known as the African dwarf crocodile, broad-snouted crocodile -a name more often used for the Asian mugger crocodile) or bony crocodile), is an African crocodile that is also the smallest living species of crocodile.

Found in lowlands to mid-height areas, in small and mid-size streams (they avoid large rivers). Generally, they live in rivers that lie in rainforest, though they will venture into the open.

They are known, in places, to be found in pools deeply isolated in Savannah. In western Gabon, there are also a group which have been living long-term in caves. It is considered vulnerable by the IUCN and is Appendix i of CITES. Where they are declining, it appears largely as a result of deforestation and hunting for the bushmeat trade. As a result, while in some regions they have a healthy population, in others (like Gambia and Liberia) they are almost lost.

In zoos in the USA and Europe there are a few of this species, however, records are not good, and quite a few of them are clearly hybrids with little conservation use. I should note, a zoo I occasionally volunteer at (marwell zoo) had one of these crocodiles until last year when it went to another zoo for breeding.

We hope to be able to list places for you to visit to see this species as soon as possible. Any of these will appear below the video and the news section (this lists all the times that this species has been mentioned (if any) in this blog). Below this, we will list all the easiest places we have connections to, to see this species.

 

Clouded leopard and Sunda clouded leopard

Clouded leopard and sunda clouded leopard

Clouded leopards are actually one of the most ancient cat species, however due to their inability to roar or purr, they cannot officially be considered a big cat (roar) or a small cat (purr) due to their definition, which puts them in an odd category. They are most closely related to snow leopards, and are in the same family as the big cats from genetic research. It has recently been confirmed that there are 2 different clouded leopard species, one on the mainland, and the other on the islands (the sunda clouded leopard.

Both species are considered vulnerable. The mainland clouded leopard is thought to number between 3700 and 5580, while the sunda clouded leopard is thought to number around 4500 3800 in Borneo and 730 on Sumatra.

Clouded leopards are found in the forests of South East Asia. Both Poaching and habitat loss threaten their future survival is not easy to see, it makes it is hard for it to be clear what its current range is. However, if you simply compare extinct to all possible remaining habitat, you can see the best possibiltiy is that range has reduced by around 50%


The clouded leopard has been split into two species – the Clouded leopard found on mainland Asia (big picture at the top), and the Sunda clouded leopard (picture above) found on Borneo and Sumatra (these Sunda Clouded leopards have not interbred for a very long time so are considered 2 subspecies). 

 

This is a further image of a clouded leopard though taken in a US zoo, which allows an easier time of getting a good view of the head.

The map above shows the former and current range for these two species. As we start to link with places on the ground, we are likely to create separate pages for each of these clouded leopard species. Below is a video of each species of clouded leopard.

We look to work with people on the ground. Do get in touch if you live or work in the area, and can help people see these incredible animals click here

The Oncilla (northern and Southern)

This is an Oncilla taken by Groumfy69 in a zoo

Oncilla (northern and southern)

The Oncilla is a small spotted cat found from central America to the Central Amazon. In 2013 it was proposed to split the species into two, as they did not interbreed, however I would argue that this should be at the subspecies level. The Southern Oncilla lives in Brazil, Paraguay and Argentina, while the Northern Oncilla ranges from central America to central Brazil – time will tell if these two cats are subspecies or are distinct enough to be considered different cat species

 

Serval

Serval

The Serval is a cat slightly bigger than domestic cats. It is a formidable jumper, and uses this to its advantage. It will usually hunt some rodents by stalking them until it is close and then leaping in the air and coming down on its back. It is also one of the few cats that regularly catches birds in flight, given its ability to jump as much as 4m up (indeed, if you see them in a zoo, it is not unusual for there to be a pile of feathers somewhere in their enclosure. The are a nocturnal savannah animal, and are found in most protected areas of sub-Saharan Africa. They are generally plentiful in any savannah with a good supply of water.
