Cheetahs were once widespread throughout Asia and Africa. However, they currently inhabit East and Southwestern Africa. In Iran, a small population of around 200 cheetahs exists.

Cheetahs are built for speed as an adult can attain distances of 110 kilometers per hour (70mph) within 3 seconds. Its unique body structure that includes a flexible spine, long legs, tail for balancing, and semi-retractable claws enable it to achieve the maximum distances. The claws of its legs act as cleats of a track to grip the ground when at top speed. The adaptations to rate also include its lungs, heart, and legs.

Scientific name:Acinonyx jubatus
Weight: 40-70 kg (Up to 160 pounds)
Height: 94 cm (34 inches)
Length: 200 cm (about 6 feet)
Gestation period: About 3 months 
Life expectancy:10-12 years in wild, up to 20 in captivity
IUCN Status: Vulnerable (2020)

General habits of Cheetahs

Most people know that cheetahs are the fastest animal on land. Some of the other general habits of cheetahs include:

  • Unlike the other big cats, cheetahs do not roar. Their vocalization includes growls when in danger and high-pitched chirp when communicating with each other.
  • Cheetah is the only big cat that can turn in the air while running.
  • Male cheetahs would usually live in groups with their siblings, while the female cheetah is primarily a solitary animal. A male grouping of the cheetah is called a coalition.
  • Male cheetahs have territories that they protect while female cheetahs would follow the herds. Males attempt to mate with females when they pass through their territories while following the herds.

Killing and Feeding habits of cheetahs 

Unlike the leopards and the lions, cheetahs are diurnal, which means that they hunt during the day. The strategy helps the cat to avoid competition with the other bigger carnivores.

Cheetahs are cursorial animals, meaning that they are adapted to run. The cats can reach a maximum speed of 110 km/h (68.35 mph. However, they are unable to sustain the pace for long. Thus, timing is vital for cheetahs while hunting.  

The main prey for cheetahs in Africa is the medium or smaller sized ungulates such as the gazelles. In community conservation lands, the cheetah will also hunt unattended goats and sheep. It is rare for a cheetah to pursue livestock when the herder is taking good care of the livestock. When food is scarce, a cheetah will go for even go for smaller prey such as hares and birds.

Because they have an advantage of speed, they have the ‘fast-twitch’ muscle fibers that provide power over endurance. Cheetahs are quite successful hunters. However, larger predators like lions and hyenas steal most of their kills.

Unlike the other big cats, cheetahs do not ambush or attack within springing distance. Instead, they begin the chase when the prey is between 70 and 100 meters (230 to 330 ft.). The hunt would rarely last a minute and is commonly at 20 seconds. The cat would knock down its prey and quickly use its canine teeth to strangle its catch.

Cheetahs would seldom scavenge prey that they did not hunt. A lone adult cheetah may hunt after between 3-5 days while a mother with cubs may need to hunt every day.

After making a kill, a cheetah may need time to catch its breath. Research shows that cheetah with cubs take a longer pause compared to other cheetahs. Probably because they must ensure the site is safe before introducing the cub for the kill. Then it would devour its prey before a scavenger emerges. At times, cheetahs would drag their kill to a hiding spot.

Breeding habits of Cheetahs

The cheetahs exhibit a polygynous mating system where one male can mate with multiple females. Moreover, male cheetahs only associate with females during mating. The male does not provide any assistance in parental care. Additionally, a female cheetah may mate with more than one male when in heat. Interestingly, the same litter can produce cubs of different fathers!

Like with the other big cats, the gestation period for cheetah is about three months. After which the female gives birth to a litter of between 2 and 5 cubs

Like other cats, cheetahs cubs are born blind and helpless. Nevertheless, the mother leaves the cubs in the nest after a day to hunt. This duration is the time the cubs are most vulnerable. After about six weeks, the cubs accompany the mother for hunts. As such, the cubs are also attacked by other predators, especially lions, hyenas, and leopards. It is no wonder that less than 10% of cheetahs’ cubs survive into adulthood.

Threats faced by Cheetahs

In 1900, cheetahs populations were estimated at over 100,000 individuals in the wild. Now, only about 7,000 cheetahs live in the wilderness of Africa. It is the most endangered of the big cats because of the following reasons:

Illegal trade of Cheetahs

Cheetah’s skin is a hot commodity in the illegal wildlife trade. Moreover, some people target cheetah cubs for pets. The illicit trade of the cat is rife in the East Africa region, particularly Kenya, Tanzania, and Somalia. We suspect that the Middle East is the destination of most cubs.

The retaliatory killing of cheetahs

Unlike most of the other predators, cheetahs do not do well in national reserves and parks. This occurs because there is heightened competition for prey at reserves. The predators would kill cheetahs and their cubs at any opportunity. As such, there is a significant cheetah population in community lands across Africa (over 80% of cheetahs are in community lands.

The fact that cheetahs inhabit community lands and hunt during the day means they could attack livestock in herding. In many cases, a cheetah would attack a sheep or goat when the herder is not in proximity. Another sad reality is that in Africa’s pastoral communities, children herd the livestock. The predator will not even see the children while pursuing prey as children are not intimidating enough.

Herders retaliate after their livestock is killed. Cheetahs and other predators are sometimes poisoned or speared.

The good news is that many conservation organizations in Africa have a compensation scheme in the event herders lose their livestock to cheetahs or other predators. Consequently, retaliation attacks reduce in areas with compensation schemes.

Loss of habitat

Cheetahs require extensive home ranges for survival. An ideal range for one cheetah would be hundreds of kilometers or miles squared. However, human encroachment is limiting the habitat for cheetahs. The implication of reduced habitats means that they will compete more with other predators like lions, hyenas, and leopards, a fight which they will quickly lose.

Lack of genetic diversity

Cheetahs are famous for their lack of genetic variation. The species barely avoided extinction at the end of Ice Age, around 10,000 years ago. After that, there was widespread inbreeding, which led to a loss of genetic diversity. Consequently, cheetahs are prone to diseases and have low sperm quality. The situation is complicated by habitat loss that further reduces genetic diversity.

What Can you do to save Cheetahs in Africa?

You can seek to support the conservation efforts in Africa’s protected areas. This support could be achieved in a variety of ways, including:

  • Donating to organizations working with protecting cheetahs in Africa
  • Spreading the word by supporting bloggers such as ourselves through sharing content
  • Not participating in the illegal wildlife trade.

There are over 1,290 documented bird species in the East African region. Globally, there are about 10,000 species of birds. Meaning that the region has approximately 13% of the world birds’ for its relatively small area. Birdwatchers find the overwhelming diversity and abundance of bird species in Kenya, Uganda and Tanzania irresistible.

But differentiating between the hundreds of the bird species can be daunting to any amateur bird watcher, like myself. It is for this reason that I decided to write a blog article of the birds in East Africa. The blog categorizes the birds into families. It is my hope that this blog will assist you in identifying the birds of East Africa.

Order Passeriformes (The Passerines)

More than half of all birds in the world are in the order Passeriformes. They are also called perching birds or less accurately, Singing birds. Some key characteristics in the order include:

  • Three toes pointing forward and one pointing backwards (the hallux), which makes it easy for them to perch
  • Developed vocal organs that allows for vocalization
  • Unique sperm and bony palate morphology (I guess those are for the serious ornithologists, let’s get into the families under the order in East Africa)

Weavers and Allies (Family: Ploceidae)

The weaver birds get their name from the intricate nests that birds in the species build. Ploceidae mostly inhabit the old world, particularly sub-Saharan Africa. Sparrows and whydahs are not in the weavers and allies family, although older publications classify the two group of birds in the Ploceidae family. About 60  species of weavers and their allies (bishops, quelea, widowbird) are found in East Africa. They include:

  • Swainson’s sparrow (Passer swainsonii)
  • Yellow-spotted bush sparrow (Gymnoris pyrgita)

Waxbills and allies (Family: Estrildidae)

They are small seed eating birds. It is not surprising that some sources classify them under the sparrow family, Passeridae. Most of the birds in the family have similar form and size, but different plumage. The largest species of the family is the Java finch which is found in Asia. Common species in East Africa include silverbills, twinspots, and firefinchs.

Each year, millions of birds migrate long distances across the world to East Africa.  Most bird species migrate to the region through flyways, which refer to well-established routes. The birds travel from Europe, Central Asia, the Americas, the Mediterranean region, and the East Atlantic to the East African region.

What are migratory birds?

Migratory birds are bird species that make a seasonal movement, mostly from Northern and Southern parts of the globe, via a designated route. These birds usually make fantastic voyages annually, particularly during the non-breeding season.

Palearctic migrants refer to bird species that breed in Asia or Europe but seasonally migrate south during the non-breeding season. Bird migration to East Africa could be broadly categorized into three main groups, namely waterbirds, raptors, and landbirds. 

·        Waterbirds (also known as aquatic birds)

They are bird species that live on wetlands or around wetlands. Most of these birds ecologically depend on water bodies.  These birds can thrive in freshwater habitats, although some species of waterbirds can still inhabit marine environments. Moreover, some waterbirds can be more aquatic or terrestrial than others. Adaptations among these birds can vary depending on their respective territories. 

Waterbirds in East Africa have adopted various strategies to enable them to exploit the variety of East African wetlands. The onset of the rainy season is a crucial trigger for migration among waterbirds.  Some common types of waterbirds that migrate to the East African region include grebes, cormorants, pelicans, storks, ibises, flamingos, swans, and ducks.

·        Birds of prey (Raptors)

Birds of prey include eagles, falcons, hawks, and vultures. Eastern Africa is an ideal habitat for numerous species of birds of prey. There are dozens of raptors migrating to the region via the Suez, most of which come to the African continent in winter.  Migrant species vary in nature and size.  Raptors that come to East Africa are either nocturnal or diurnal.  The latter primarily hunt on sight, while the former hunt by using hearing and sight. Raptors can either hunt on their prey or consume food they have not killed.  An example of the latter is the vultures that prey on carcasses and sometimes wounded animals.  Some raptors that migrate to Africa (not necessarily East Africa) include black kite, Griffon’s vulture, Egyptian vulture, Pallid Harrier, Hen Harrier, Marsh Harrier, long-legged buzzard, honey buzzard, Steppe eagle, red-footed falcon, and kestrel among others.

·        Landbirds

Landbirds include bird species such as swallows, common cuckoo, songbirds, and the turtle dove.  These birds can breed in farmlands and agricultural areas, and then cross the vast Sahara desert to East Africa’s open savannahs where they winter in large groups. These birds have remarkably complex, long-distance migration cycles.  Nevertheless, landbirds are more vulnerable to prevailing environmental changes than resident species.  Upon arriving in East Africa, these birds can concentrate together temporarily before dispersing into suitable habitats.  As such, their conservation is quite challenging.

Birds that migrate to East Africa

East Africa has one of the richest avifauna in the world. Close to 200 Palearctic migrants have been spotted in the region. Some of such bird migration to East Africa include the following:

1. Black stork (Ciconia nigra)

The large bird belongs to the vast stork family of Ciconnidae. It measures 95 to 100 cm (approximately 40 inches) on average from the beak to the tail. Black storks have distinctive white underparts, and overall black plumage pointed red beak and long red legs.  They are widespread despite being among the uncommon bird species.

Black stocks breed in scattered spots across Europe. The breeding sites include Spain, Portugal, and other eastern and central areas of the larger European continent. The long-distance migrant migrates to the tropical sub-Saharan area during the non-breeding season. It nevertheless avoids flying over the Mediterranean Sea when migrating to Africa on its way to East Africa. Black storks usually migrate to East Africa from August to October.

2.      The African skimmer (Rynchops flavirostris)

 

The tern-like bird belongs to the Laridae family of birds. It inhabits the rivers, lagoons, and lakes of sub-Saharan Africa. The migrating bird has a black back, long wings, crown, and hindneck. Its forehead and remaining body are overly white. The African skimmer is regarded as an intra-African migrant. 

African skimmers come to East Africa when water levels in the lakes and rivers have fallen substantially. They mostly prefer migrating to the region at the onset of the long, dry season. They mostly choose this season since it coincides with their breeding season. Once the breeding is over, these birds move northwards in readiness for the rainy season. Although IUCN lists it as Near Threatened, some conservationists claim the species could be vulnerable or even endangered.

3. The ruff (Calidris pugnax)

The medium-sized wading bird breeds in wet meadows and marshes across northern Eurasia. It is highly migratory, and it lives in large flocks in its respective winter grounds.  East Africa is one of the favorite wintering grounds for this bird. Overly, the bird has a potbelly and a long neck. Males are way larger than females.

It breeds in Asia and Europe and then migrates to Africa via a flyway that takes them through the Mediterranean and the Atlantic. Huge flocks of this bird then travel to East Africa and other parts of Sub-Saharan Africa.

4. Common sandpiper Actitis hypoleucos

This tiny Palearctic wader has white underparts, greyish-brown upperparts, and short yellowish feet and legs. It breeds in temperate Asia and subtropical Europe. The bird migrates to East Africa annually at the fall of the breeding season.  Hundreds of common sandpipers gather at the Palau region for breeding before migrating to East Africa via the Suez. The waterbird prefers migrating to East Africa’s freshwater wetlands. It is a gregarious bird often seen in large flocks. 

5. Wood sandpiper (Tringa glareola)

The mid-sized waterbird has a brown back, a short bill, and long yellowish legs. It differs from other sandpipers thanks to its white rump patch. It breeds in the Scottish Highlands and subarctic wetlands. It migrates to freshwater bodies across East Africa after the breeding season, where it inhabits during wintering. They are mainly found in singles or small flocks. It is also uncommon for the wood sandpiper to mix with other bird species.

6. Common Greenshank (Tringa nebulari)

The waterbird is prevalent throughout northern Europe. The migratory bird prefers to winter in sub-Saharan Africa, specifically in East Africa’s wetlands. It is brown in winter and grey-brown while in breeding plumage. They have a striking resemblance to marsh sandpipers while in water.

7. Ospreys and Cuckoo

Like all of the Palearctic migrants, ospreys winter in Africa and move back in Europe from March onwards. It is females who usually start the migration then followed by males and their young. Compared to other migrating birds, ospreys are slower in migrating, probably because they make stopovers at their favorite feeding sites. A famous osprey traveled for 7,000 kilometers (4,350 miles) from Finland to Kenya. Unfortunately, the bird died after being trapped in a fishing net.

Another bird, a Mongolian Cuckoo, named Odon also traveled for 8,000 kilometers (4,970 miles) from China to Kenya. It shows that bird migration to East Africa is vital to the survival of various avian species. 

While East Africa is an excellent migration destination for birds, most of these migrating bird species are vulnerable to poaching and a variety of environmental threats. As such, conservative action needs to be taken to protect these species.

They may not be the most giant animal in the African savannas; however, the habits of lions make them the ‘King of the jungle’. The lion is not the biggest cat, either; that title belongs to the tigers. 

Conservation of lions in Africa
Despite their title, lions habitat is savannas and grasslands (Image by Alexas_Fotos from Pixabay)

Historically, lions were present across Africa, Europe, and Asia. Currently, most lions occur in Africa, with a small population of Asiatic lions present in India. This article focusses on the African lion.

Lions have more pronounced sexual dimorphism as compared to the other cats. Meaning it is easy to distinguish between mature male and female lionesses. The male lions are not only bigger, but they have manes that darken with age.

Scientific name:Panthera leo
Weight: 150-250kg (Male); 120-150 kg (Female) 
Height: 100-120 cm 
Length: up to 350cm for male and 275cm for female 
Gestation period: 109 days 
Life expectancy: 10-18 years in the wild, but can live up to 30 years in captivity
IUCN Status: Vulnerable 

General habits of lions

The mane is one of the features that gives the species is majestic look. Some of the general habits of lions include:

  • Lions are social cats. They live in groups called the pride. Lions in a pride would hunt and live together. A pride could have as few as four lions or as many as forty lions. Most prides have between ten and twenty lions.
  • Each pride has its territory which can be small where prey is abundant or as large as 400 square kilometres where prey is scarce. Territories have a core area that is fiercely defended compared to fringe areas where a pride can allow other lions to roam.
  • Another majestic habit of lion is roaring. Both male and female lions roar can be heard over 8 kilometres away.
  • Roaring is one way which lions mark their territories. Another way is using scent markings. Males would urinate on bushes and the ground to demarcate their territories. They also defecate or rub against bushes to leave their scents.
  • Apart from roars, lions have other vocalizations including purrs, growls, and even meows.
  • Lions appear affectionate as they spend time licking, head rubbing and purring while resting.

Killing and Feeding habits of lions

The lion kills a variety of prey ranging from rodents to cape buffaloes. Heck, they could even take down an injured elephant or giraffes. One advantage of living in prides is the ability to take on large prey. Although they are powerful, lions often steal prey from other predators including hyenas, cheetahs, even jackals.

Hunting, like roaring, is done at either dawn or dusk. Typically, a lion would stalk prey and run it down in a short rapid burst. The cat then jumps on the prey’s neck until it is suffocated. Alternatively, lions would trip the hind legs of its pursuit, and quickly grab the neck of the prey when it falls.

Nevertheless, most hunts conducted by lions fail. Partly because they tire after short distances and they disregard the direction of the wind. As such, the prey usually picks up the lion scent and escape.

Most hunts in a pride are conducted by lionesses. Regardless, male lions are adept hunters. A male lion can eat 35 kilograms of meat in a single kill and rest for around a week before hunting again. In places where prey is readily available, lions would rest for up to 22 hours, and hunt for only 2 hours.

Other animals could also steal kills from lions. A cackle of hyenas could chase one or a few lions from their kill. But it is a high-risk game. One bite or paw stroke from a lion would kill a hyena. After all, an adult male lion is twice the size of a hyena and up to four times its weight.

Habits of lions

Breeding habits of lions

The male and female lions are polygamous and would breed throughout the year. However, females are restricted to one or two males in their pride during mating. The copulation process is intense as the pair mate up to 50 times in a day, after every 20 minutes.  This copulation process happens for 3-4 consecutive days when the female is on heat. The prolonged copulation seeks to stimulate ovulation and secures the paternity of the offspring as it excludes other males. Like the other cats, lions’ penises have backward-pointing spines that seek to stimulate the lions to ovulate while mating.

The gestation period for lions is about 3.5-4 months. A lioness would give birth to between 1 and 6 cubs, but the range of 2-4 is more common.

The cubs are born blind with dark spots which disappear as they grow. Cubs will accompany their mothers by three months and are weaned at six months. They can participate in kills when they are about one year old. However, they cannot survive in the wild by themselves until they are two years.

Male cubs are expelled from the pride at about three years of age. Similarly, some female cubs are expelled while others are retained in the pride when they attain three years. Expelled females may immediately join other prides or become nomads to join prides later. However, some male lions remain nomads for life as they are unable to take over prides. Mating opportunities for nomads are scarce.

Although males mature at three years, they will need to be at least five years before attempting to take over a pride.

When a male lion or a group of males takes over a pride, they would immediately kill the cubs in the pride. The purpose of the infanticide is to shorten the time needed for the lionesses to mate again. However, lionesses would attempt to protect their cubs from the infanticide by hiding the cubs or directly fighting with the lions. Generally, lionesses have a higher chance of defending older cubs as they were leaving the pride anyways.

Over 80% of lions’ cub die from various reasons, including infanticide. When there is a scarce food supply, lionesses could also abandon their young. Other predators such as hyenas, leopards, and wild dogs could also kill the cubs. In the Masai Mara, I have seen buffaloes trample lion cubs to death.

Threats faced by lions

Most conservation organizations estimate that about 20,000 lions are left in the wild.

Hunted for its Legacy 

The majestic nature of the cat means that the lion is a prized hunting trophy. As such, game hunters feel accomplished by killing lions. Moreover, in some African cultures, such as the Maasais, killing lions is considered a sign of bravery. Such beliefs contribute to the declining number of lions.

The retaliatory killing of lions

Lions also attack livestock, especially cattle and sheep. When they do, community members may poison or spear lions in retaliation. Lions are particularly targeted in retaliation killing because of their apparent ‘contempt’. Many carnivores would flee and leave the carcass when they realize human pursuit. Not the king of the jungle. Sometimes lions would devour a livestock carcass when humans are watching.

The good news is that many conservation organizations in Africa have a compensation scheme in the event herders lose their livestock to lions or other predators. Consequently, retaliation attacks reduce in areas with compensation schemes.

Loss of habitat

As human being population continues to grow, so is development. The growth of agriculture, settlement, and roads means that we continue to encroach to lions’ habitats.

What Can you do to save lions in Africa?

You can seek to support the conservation efforts in Africa’s protected areas. This support could be achieved in a variety of ways, including:

  • Donating to organizations working with protecting lions in Africa
  • Spreading the word by supporting bloggers such as ourselves through sharing content
  • Not participating in the illegal wildlife trade

The African leopard is one of the fascinating cats in the world. Globally, there are at least nine subspecies, but this article focuses on the habits of leopards in Africa. 

Image by Barbara Fraatz from Pixabay

Most leopards are light-colored with rosette (resemble a rose) spots. Black leopards (also called black panthers) have rosettes too, but they are not easily visible. They are the smallest members of the big cat category that includes tigers, lions, cheetahs, cougar, and jaguars. The term ‘big cats’ is sometimes used to define only animals of the Panthera species.

Scientific name:Panthera pardus
Weight: 40-90kg (Male); 30-60 kg (Female)
Height: around 60 cm
Length: 170-300 cm  
Gestation period: 90-105 days
Life expectancy: 12-17 years in the wild, but can live up to 24 years in captivity
IUCN Status: Vulnerable (2020)

General habits of leopards

Some of the general habits of leopards include:

  • The leopard is mainly a nocturnal animal. Nevertheless, it can be spotted basking in the sun during the daytime.
  • They are solitary cats. When two or more leopards are spotted together, they are either mating or raising the young. They could also be fighting for territory.
  • Although they are the most common and widespread of cats, they are also the most elusive. Because they are shy and secretive.
  • It is an agile climber and would often take its prey to trees. This habit keeps its kill safely from other carnivores in the wilderness, such as hyenas and lions. Pound for pound, leopards are the strongest big cats. They can carry prey heavier than themselves up a tree!
  • They have a varied vocalization, including purrs, growls, and coughs.
  • The leopard will mark its territory by scratching trees or use a urine scent. The territories range from tens to hundreds of square kilometers. A male leopard may share its territories with females but not other males.

Killing and Feeding habits of leopards

The leopard is not a picky eater. It would kill and eat almost anything it can overpower. It can feed on anything from rodents to birds to snakes to waterbucks. Nevertheless, its most common prey are medium-sized antelopes.  It has a particular liking for dogs and baboons. In fact, leopards and baboons are mortal enemies. A troop of baboons could even attack (and kill) a leopard during the day.

Like many wildlife, leopards generally avoid humans. However, they could also attack humans. As they often hunt baboons, they also target the neck of humans.

The leopard would stalk its prey in the bushes by stealth movements. It would attempt to get as close as possible to its prey before attacking it. It can stalk its prey for hundreds of meters, maintaining its head low. Then, it would make an explosive run pouncing on the prey with a killer bite on the nape of the neck or the throat. A leopard does not chase prey over long distances and will abandon a hunt when the element of surprise is lost.

A swipe of the paw kills small prey, such as rodents and birds.

Apart from stalking, leopards can camouflage in trees and pounce on its targeted prey from above.

It is a strong swimmer, too, and would even hunt fish in the water. It is the definition of a non-picky eater. No wonder it is widely distributed for a big cat.

A leopard would lick the fur of the hunted prey before eating. Sometimes, leopards would discard the stomach content before consuming the prey. Usually, it will start consuming the carcass with the chest and thighs.

It may go for days without drinking water as it gets its water needs from the prey it eats.

Leopards will scavenge if they get the chance. A leopard may chase a hyena or a cheetah from its kill. It can even eat rotten meat with ease.

Breeding habits of leopards

A female leopard attracts the male through the smell of urine. During mating, they stop their solitary habits as they mate for days. They even hunt and share kills during mating.

A female leopard can give birth at any time of the year. Usually, they would give birth to two greyish cubs with hardly any spots. The number of cubs ranges from two to four. The female would move her cubs from place to place until they are old enough to play or learn to hunt, usually at about five months. As leopards are solitary animals, the cubs leave their mothers after around two years. A leopard is ready for breeding after 2-3 years.

Threats faced by leopards

The big cats face several threats that are threatening their existence in the wild. Before 1800, the cat was conspicuous in virtually all over Africa. It was also common in many parts of Asia, including China. However, leopard has lost up to 75% of its range. Some of the modern threats to the leopard include:

Hunted for its beauty

The leopard’s beauty is also its curse. Many hunters target their soft fur for making robes and coats. Its whiskers, tail, and claws are also hunted for fetishes. As such, leopards are targets for illegal wildlife trade.

The retaliatory killing of leopards

Leopards are opportunistic carnivores. Meaning that they would hunt livestock if the opportunity arises. A leopard would usually kill one goat or sheep in a herd. However, it is not uncommon for one leopard to kill dozens of livestock. Some conservationists claim that such leopards have canine distemper.

Herders in Africa will often kill leopards if they attack their livestock. Conservation organizations in many pastoralist communities have a predator consolation scheme that pays herders for livestock killed by leopards and other wildlife.

What Can you do to save leopards in Africa?

You can seek to support the conservation efforts in Africa’s protected areas. This support could be achieved in a variety of ways, including:

  • Donating to organizations working with saving leopards in Africa
  • Spreading the word by supporting bloggers such as ourselves through sharing content
  • Not participating in the illegal wildlife trade

The black and blue wildebeest

The species has two subspecies in blue and black wildebeest. What is the difference between the blue and black wildebeest?

  • In both species the male is larger than the female. Generally, the blue wildebeest is larger compared to the black wildebeest.
  • The horns of the blue and black wildebeests differ as the latter curve upwards while those of blue wildebeest curve towards the skull.
  • The blue species has a grey colour with a bluish sheen as compared to black which has brown coloured hair.
  • The blue specie has a wide habitat range inclusing Kenya, Tanzania and most of Southern Africa while the black is restricted to Southern Africa. The blue wildebeest is known for its migration unlike the black species.

The Great Migration

  • The famous wildebeest migration occurs mainly because the species search for food.
  • The Great Migration sees over 1.5 million wildebeest, 200,000 zebra and a large group of antelopes travelling cross country between the Serengeti of Tanzania and Masai Mara of Kenya  
  • During the migration around 250,000 wildebeest and 30,000 zebras are die off each year not only because of predation by carnivores but also from thirst, craving, and fatigue.

Reproduction

  • Between January and March, half a million wildebeest are born each year in the Serengeti. In February, the month with the highest calving rate, around 8,000 wildebeest are brought into the world every day.
  • Pregnancy lasts 8.5 months, and it closes with a single baby. Female conceives in the middle of her. 80% of calves are designed during a similar 2-multi week time frame, just before the rainy season.
  • The calves can stand up and dash just after birth and have short straight horns that bend as they become more seasoned.

Behaviour

  • Despite their size, the black wildebeest is a quick runner so that they can escape from their main predators, lions, leopards, hyenas and African wild dogs. They have estimated at up to 80 kph. They additionally must be careful about crocodiles when they get a drink or cross a large river.
  • Males likewise attract females by rubbing a scent (created in the preorbital and interdigital gland) into the ground. They will urinate and defecate to mark their breeding an area and to keep other males off.

The wildebeest migration is the largest of mammals. It is no wonder that wildebeest migration is one of the seven new wonders of the world. Despite the spectacle, habitat fragmentation is threatening the survival of the species. Moreover, some livestock keepers deliberately kill the species to reduce competition for pasture and spread of zoonotic diseases.

Height

100 cms (average)

Length

120-150 cms

Life expectancy

12-15 years (wild)

IUCN Status

Least concern

 

Reproduction

  • Pregnancy lasts seven months and ends with one child. Female leaves the crowd toward the end of pregnancy and hide its baby barely any days after birth (when it is still extremely frail).
  • Impala are usually born around noontime as this is the most secure time to conceive since a large number of their enemies are resting. Still, predators kill half of the new-born within the first few weeks of life.
  • Main predators of impala are lions, African hunting dog, cheetah, leopard, hyenas and pythons.

Ecology and adaptation

  • Impala is herbivore (plant-eaters) which eats grass, herbs, bushes and leaves on the trees. Impala additionally eats acacia pods and fruits. Impala have the ability of being both a grazer and browser.
  • Impalas make seasonal migrations from high to lower ground according to the availability of food
  • The impala shows two characteristic leaps-it can jump up to 3 meters (9.8 ft), over vegetation and even over another impala. It covers distances of up to 10 meters (33 ft); the other kind of jump include, a series of increases in which the animal lands on its forelegs, move its rear legs mid-air in a kicking design, arrives on each of the fours and afterwards bounce back. The jumps may appear uncoordinated, but they are actually an anti-predatory technique
  • Impala lives in crowds made out of creatures of just one sex. Size and sort of the group rely upon the climate conditions and availability of food.
  • Impala produces barks-like sounds to alarm other members of the herd in the case of danger.
  • Horns are used for protection against predators and in the battles for dominance in the herd. The horns in males may be as long as 90 cm long.

Impalas face a serious conservation challenge as they are often hunted for game and bushmeat. Furthermore, habitat fragmentation is causing impalas to lose their homes.

Monkey is a collective term that includes groups of primates. In fact, there are over 250 species of monkeys in the world, including baboons and apes. The vervet monkey (Cercopithecus aethiops) is among the most common monkey in East and South Africa. The male vervet is easily noticed as it has a red penis and a blue scrotum.

Image by Barbara Fraatz from Pixabay

The blue scrotum in vervet monkeys is  neither caused by sexual frustration nor hormonal shifts. Instead, it is thought that the blue colour emanates from the Tyndall effect. Young males have a duller scrotum that strats to become brighter during adolescence. Thus, the blue colour is likely to increase the sexual attractiveness of males. 

Interesting facts about most monkeys

  • Monkey eat animals, plants and Earth, organic products, creepy crawlies, blossoms, and reptiles. They strip the bananas and throw the skins.
  • They walk on their knuckles to prevent the body weight from landing on their hands.
  • Monkeys are long-lived, surviving in the wild anyplace somewhere in the range of 10 and 50 years.
  • A few types of monkeys can see on colour while others can only be able to distinguish between black and white.
  • Monkeys communicate using facial expressions, vocalizations, and body movements.
  • Trees, grassland, mountains, forest, and high fields are the most common place where monkeys live.
  • Monkeys are considered a pest in certain areas. They murdered because they are destroying crops humans have been trying to grow.
  • The biggest monkey is the male Mandrill, which weighs almost around 35 kilograms and 1 meter long.
  • The gestation period lasts between 7 days, contingent upon the species. Most monkeys give birth to just one child in turn.
  • Grooming is a significant part of socialization for monkeys. They will spend long periods removing items from the fur of each other. They are social animals that usually eat, sleep, and travel in groups.
  • The Old-World monkeys live in Asia and Africa, and the New World monkeys live in South America.
  • The louder monkeys are Howler monkeys; their howls can be heard for around three miles in an open area and two miles in the forest. They spend 80% of their energy resting.
  • Monkeys are found wherever on Earth, except Australia and Antarctica.
  • The tip of their tail can support the whole weight of their body. Some have prehensile tails that can snatch and hold objects. Some use their fingers and toes to get a handle on objects.

Most monkeys are considered as pests in agricultural systems. As such, they are often poisoned and killed.

The Olive and yellow baboon are common in East Africa. Apart from the Hamadryas baboon that is found in the Red Sea and Arabia, all the other baboons are Savanna baboons.

Interesting facts about baboons

  • Male baboons are significantly bigger than female baboons, twice bigger to be definite. Baboons reach a height of 14 to 30 inches when estimated at the shoulder, and a weight of 50 to 100 pounds.
  • Unlike other monkeys, baboons lack the prehensile tail. This means that they are incapable of using their tails as their hands.
  • The body of the baboon is shielded with fur that can be black, olive, or yellow. Males and females look like the other the same, and again, females don’t have lengthy hair round their necks.
  • Baboons have long, dog-like muzzle and strong jaw furnished with sharp canines.
  • They take any kind of food that is available at the moment (pioneering feeders). Most of their eating habit embrace fruits, seed, berries, roots, tree covering, tree sap and different creepy crawlies, shellfish, fish, birds, and small mammals.
  • They have a sign of communication that includes vocalizations, facial expressions, posturing, and gesturing.
  • Baboons have a similar number of teeth and the same dental pattern as a human being.
  • A female baboon will stay pregnant for a half year, and birth usually ends up with one offspring. The mother will convey her family near her stomach while she moves.
  • It can survive for 30 years in the wild until 45 years in captivity, because of an absence of predators.
  • Baboons and leopards are ancient enemies. At night, leopards often stalk and pick sleeping baboon from a troop. There are reports of baboons troops that attack and kill leopards during the day.
  • The baboons are social and live in groups called troops that average with about 50 baboons. Females and juveniles are the core members of troops, as the males could move in and out.

Although they are listed as ‘Least Concern’ by IUCN, baboon conservation faces challenges.  Humans consider baboons a pest species because they raid their farms. As a result, they are often poisoned and killed. Moreover, baboons are also hunted for their skin and are used as test animals in the laboratory.

The hartebeest is a common sub-Saharan African antelope, which is common in East Africa. The Swahili name for the antelope is Kongoni. There are eight subspecies of the hartebeest; the Bubal hartebeest is extinct while the rest have decent numbers in the wild (except Tora hartebeest that is listed as critically endangered). The features of the mammal are defined that it makes it easy to identify the species. 

Although they have a clumsy look, hartebeests are among the most evolved antelopes as they are fast (reaching speeds of up to 70 km per hour) and enduring runners. It is no wonder that they are nicknamed ‘tough ox.’

Interesting facts

ü  They have weird shaped horns
