LEMUR PART TWO



FULVUS OR BROWN LEMUR

Their CALLS
Lemurs of Madagascar have a great variety of calls.

The
fulvus lemur sound like a dirty laugh.




MOUSE LEMUR
The mouse lemur has a twitter when it is disturbed or threatened.

The
sifaka calls sounds its name.

The most strange call has the aye-aye which sounds unearthly when in the middle of the night. Its like a tambourine.


One of the most beautiful calls in the entire animal kingdom belongs to the
indri. It sings in a descending chorus to protect its hilltop territory.


SIFAKA LEMUR

FAMILY LIFE
The sportive lemurs and the mouse lemur lead a solitary lives. The other species have such a complex social organisation that scientists who study primates are keen to uncover origins of human behaviour. There is a great variety.

Ringtailed lemurs are competitive, with a strict hierarchy dominated by the mothers. The males just follow the group travelling around their territory competing for their mating rights. They always drink last and in a drought they die first.

Sifaka are in  friendly groups of mother, aunties and uncles and know no aggression.

The mouse lemur has several babies but most of the other lemurs have only one. To begin, the mother carries it through threes clinging to her belly. When it grow bigger it climbs on her  back and soon makes its first excursion.


NEW DISCOVERIES
Recently there were two new species of lemurs discovered.

The first was a re-discovery of the golden bamboo lemur - thought to be extinct.


The second is a whole new species of
sifaka named golden crowned lemur. It was discovered in the dry forest in northern Madagascar which was on the verge to be felled to make charcoal.

RELATIONSHIP WITH MAN
Madagascar was an inhibited island until 2000 years ago. The lemur and other species had the place to themselves for over 50 million years.

When human pioneers arrived from Africa and Indonesia in their canoes they had no fear of man.


Hunters could kill a large number immediately. A loss of at least 20 species, when they burned the forests to create pastures for their cattle. Even today the destruction and burning is still going on.

The
rainforests are slashed and  burned to grow hill rice on the slopes.  Madagascar's soil is fragile and misuse will have a catastrophic effect. Since the population increases the pressure on Lemurs and there habitats will continue.

CONTINUING PERSECUTION
Although there are now protective legislation lemurs are still hunted for food and the forests felled
.
One point which is never mentioned is corruption of the law by powerful town dwellers. Unless this is stopped lemur and other important species only to be found in Madagascar will never  be safe.

GORILLAS



SILVERBACK MALE
Gorillas are man’s closest relatives. The Gorilla became known as aggressive and ferocious but it is completely unfounded.  He is the largest primate. The gorilla is a vegetarian and of gently nature.

It is thought that gorillas at their beginning lived in trees but today only the younger members are climbing and the adult stay on the ground because they are too heavy. Mother Nature provided them with strong grasping fingers and thumb for gripping. Their arms are very strong and designed for swinging from trees to trees. It also has, like man, a good binocular vision for judging distances.  Although very well equipped for climbing trees it is only the young ones which climb.

The adult stay on the ground and walk on its feet and pivoting on his knuckles of its hands.

The colour of its fur can vary. The western lowland gorilla living in the Cameron, Central ~African Republic, Gabon, Congo and Equatorial Africa has a brown-greycoat. The well known male silversaddle extends to their rump and thighs.

WESTERN GORILLAS


The eastern lowland gorilla living in easy Zaire in the forests of Lualaba, or Upper Congo River, to the foothills, has a black coat. The male silver saddle is smaller but its chest is larger and so are his jaws and teeth.


LOWLAND GORILLAS

The mountain gorillas are living in Zaire, Rwanda and Uganda at an altitude of 1650-3790m. They are in the foothills of the Virunga volcanoes and mountains bordering Lake Kivu.  It is very much like the eastern gorilla but has lager jaws, teeth, longer hairs, especially on the arms

It mainly eats leaves and stems and there is plentiful in his habitat but they have to eat huge amount.  They live in family groups and move slowly about in their territory which can range from 5 to 30sqkm. They never stay a long time and it gives the plants to grow again. They feed in the mornings and afternoons. Midday they take a rest and at night they make nests from leaves and branches and sleep in it.

They eat a wide range of vegetation but prefer plants with stringy stems. They are also fussy eaters like all primates. It had been seen they pull their food apart and if there are any discolouring they throw it away. 


FAMILY
It is the adult silver back which is the centre of the family group.  He has a favourite female and she is second in command.  The rest of the family has to establish their status in the group.

Other males might be challenging the dominate male of the group for his harem but he mostly get sent off by showing their teeth, chest beating and hooting. Sometimes young males chases away the old dominate male. The new male will kill all the babies fathered by the old male and start mating with the females to establish his own family.

 Baby gorilla starts to crawl at the age of nine weeks. Till such time it clings to his mother belly. It is weaned at an about three and half years of age, and then the mother starts mating again. However, the baby is still not able to fend for itself and half of the babies die. An incoming male sometimes kill the baby which is not his own and therefore the female makes sure to chose a very strong male who is able to defend his family.

The female is not sexually mature until it is seven or eight years old but only starts breeding when it is ten years old.  The male reaches adult hood at the age of 15-20 years old.

GORILLAS AND MAN
Chimpanzee and Gorillas are the closest to man.  Man has no tail and walks upright.  Both man and gorilla are intelligent. The similarity is also in the bone, muscles and internal organs. The difference is that the gorillas have shorter toes and longer arms. His big toes are thumb-like.

The gorilla received a name for being fierce but it was due to the earlier explorers to make out they had great courage.  Therefore for many years it was believed that the gorilla was dangerous. It was discovered that the male gorilla only attacks when he feels his family group is threatened and with that his breeding rights.

Thousands of tourist travel to Rwanda to watch gorillas and are within a few metres from them. Nobody ever has been attacked.

CONSERVATION
Mountains gorillas are in great danger of extinction. The main reason is that the forests round the Virunga volcanoes were cleared for agricultural use.  It is thought that there are only 350 gorillas left in the wild. In spite of foothills of Virunga Mountains have been declared a National Park and the gorillas are a declared a protective animals a terrible trade in skulls and severed hands continues. They are sold on to tourists as ‘souvenirs’. There again if the tourists wouldn’t be so pathetic as to buy it the natives would not kill them. It is again the demand which causes the damage.

At first the poachers kills the male with a spear. Then they kill the mother and take the babies for selling them. The buyer couldn’t care less if the young gorilla dies soon after mostly from the wrong food and emotional shock.  All this is a disgraceful way to behave and to destroy such magnificent animals.

The lowland gorillas are 9,000 – 10,000 are in the wild and the eastern gorillas are assumed to be 4,000 but nevertheless they also suffer of loss of habitation and illegal hunting.

PINE MARTEN



PINE MARTEN IN SCOTLAND
Britain's rarest carnivore is the Pine Marten. It is the size of a cat. It measured from head to body 18 in (45 cm) and 9 in (23 cm) the tail. Nature equipped it with sharp teeth and claws to be a successful hunter. It has scent gland to mark its territory and leaves droppings on high grounds.
The male pine marten is call dog and the female is called bitch.
For centuries the pine marten has been hunted for its fur. It has a rich brown long fur with a bushy tail. Its ears and throat are creamy-yellow. Its legs and feet are strong to enable it to climb trees. It has the lair and breeding den in hollow trees. Also in rock fissure or old bird's nest.
The name pine marten was given because it was only found in matured coniferous forest such as Caledonia Pine Forest. Today, it adapted itself to live in mixed forests.
The diet of a pine marten is of a great variety such as field voles, small birds, frogs, beetles, and worms. It also eats birds' eggs, berries, nuts and fungi. The pine marten either lives in solidarity or in pairs.
Its mating season is from July to August and the young are not born till next March or April. They have one to three young ones and they are called kits. They are born blind. Only the females rear them. At six months they are fully independent and leave home to find their own territory.
The pine marten was widespread in Britain until 1800. Then their numbers declined and the lowest was by 1900. The reason was loss of habitat and also being hunted for its fur.
A planting of forests are hoped to bring the pine martin back from extinction and it will spread widely again.
Today, you will find pine marten in the north and west of Scotland only but their numbers are increasing again due to new habitats. A Law was also brought in that it is illegal to hunt pine marten.
