The crow

The crow


Introduction: The crow is the most common bird in Bangladesh. It is seen very where in Bangladesh. People for its harsh voice dislike it.

Description: The crow is a black bird. Its body is covered with black feathers. It looks ugly. It has a harsh voice. Every day we hear its harsh voice from the daybreak. Its bills are very strong. It also has two crooked feet and sharp claws. Its wings are strong and eyes are sharp.

Eating Habit: Crows are omnivorous and eat grain, berries, insects, carrion, and the eggs of other birds. The crow’s habit of eating cultivated grains has made it very unpopular with farmers, who often try to kill the birds.


Importance: Crows also eat many economically harmful insects. They feed chiefly on the ground, where they walk about sedately. Crows are gregarious, and at times, they roost together in great numbers, but most species do not nest in colonies. Each mating pair has its own nest of sticks and twigs, usually high up in a tree, in which are laid five or six greenish-to-olive eggs that have darker speckles. A crow may live 13 years in the wild and more than 20 years in captivity. Some pet crows “speak” and in the laboratory some have learned to count to three or four and to find food in boxes marked with symbols.

Conclusion: Though people dislike crows for their ugliness, nasty habit, and wickedness, they are useful to us. They keep our environment clean by eating garbage and rotten animals. They also teach us to be active and united.


Tigers

Tiger


Introduction: Tiger is the largest member of the cat family. Like the lion, leopard, and others, the tiger is one of the big, or roaring, cats. Only the lion in strength and ferocity rival it.

Where Found: The tiger is thought to have originated in northern Eurasia and to have moved southward. Its present range extends from the Russian Far East through parts of China, India, and Southeast Asia.

Classification: There are about seven or eight generally accepted races of tiger. Of these, the Javan tiger, Bali tiger, and Caspian tiger are believed to be extinct; the Chinese tiger is near extinction; and the Sumatran, Siberian, and Indian subspecies are listed as definitely endangered.

Size, Color and Other characteristics: The size, colour, and striped markings of the tiger vary according to locality and race. Tigers of the south are smaller and more brightly colored than those of the north. The Bengal tiger and those of the islands of Southeast Asia are bright reddish tan, beautifully marked with dark, almost black, stripes. Their underpants, inner sides of the limbs, the cheeks, and a large spot over each eye are whitish. The very large and very rare Siberia tiger of northern china and Russia, however, has longer, softer, and paler fur. There are a few black and white tigers. The tiger has no mane, but in old males, the hair on the cheeks is rather ling and spreading. The male tiger is larger than the female. A male tiger may attain a shoulder height of about I m; a length of about 2.2m, excluding a tail of about 1 m; and a weight about 160-260 kg, or a maximum of about 290 kg.

Food: The tiger is a carnivorous animal. It lives on flesh of animals. It drinks the blood first, and then feeds on the flesh.


Habitat: The tiger lives in grassy and swampy areas and forests. It also haunts the ruins of buildings such as courts and temples. It swims well and enjoys bathing. Under stress, it may climb trees. The tiger hunts by night and preys on a variety of animals, including deer and wild hog. It generally avoids healthy large beasts, although, in some instances, it attacks elephants and adult buffaloes. Cattle are sometimes taken from human habitations. An old or disabled tiger or a tigress with cubs may find human beings an easier prey and become a man-eater.

Reproduction: In warn regions the tiger produces young at any time of year; in cold regions it bears its cubs in spring. Litter size is usually two or three, and gestation period averages 113 days. The cubs are striped and remain with the mother until about the second year, when they are nearly adult and are able to kill prey for themselves. The tigress does not breed again until her cubs are independent. The average life span of a tiger is about 11 years.


Conclusion: The Royal Bengal Tiger is an endangered species. The number of this type of tigers is dwindling day by day due to indiscriminate poaching. It has been hunted for spot and for fur. It is valued for the supposed curative and protective properties of various limbs of its body. There is no doubt that steps should be taken to stop this killing. Otherwise, this majestic creature will be extinct soon.

The horse a great friend to man.

The Horse


Introduction: The horse is a great friend to man. In prehistoric times the wild horse was probably first hunted for food. It is supposed that the domestication of hordes took place long after the domestication of the dog or of cattle. It is supposed that the horse was first used by a tribe of Ind-European origin that lived in the steppes north of the chain of mountains adjacent to the Black and Caspian seas. Influenced by climate, food, and humans, the horse rapidly acquired its present form.

Description: The horse is a four-footed animal. Usually it is the size of a cow, Its body is covered with short hair. Its skin is soft and glossy. It has no horns. It has mane or long hair on its neck. It drives away fly and other insects with its long tail.


Usefulness: Horses draw carriages, cart etc. The also carry loads on their backs and lough the land. The horse serves its master in travels, ears, and labors. Man rides horses. Horses are used to run races. They are also used in hunting and circuses. Even after death horses provide us many commodities. Long before their domestication horses were hunted by primitive tribes for their flesh. Horse-meat is still consumed by people in parts of Europe and in Iceland. It is also the basis of many pet foods. Horse bones and cartilage are used to make glue. Tetanus antitoxin is abstained from the blood serum of horsed previously inoculated with tetanus toxoid. From horsehide a number of articles are manufactured, including fine shoes and belts. The cordovan leather fabricated by the Moors in Cordoba, Spain, was originally made from horsehide. Stylish fur coats are mad of the sleek coats of foals. Horsehair has wide use in upholstery, mattresses, and stiff lining for coats and suits; high-quality horsehair, usually whit, is employed for violin bows. The Scythian s for fuel used horse manure, which today provides the basis for cultivation of mushrooms. The Scythian, the Mongols, and the Arabs drank mare’s milk.

Form and function: A mature male horse is called a stallion, the female a mare. A stallion used for breeding is known as a stud. A castrated stallion is commonly called a gelding. Formerly, stallions were employed as riding horses, while mares were kept for breeding purposes only. Geldings were used for work and as ladies riding horses. Recently, however, geldings generally have replaced stallions as riding horses. Young horses are known as foals; make foals are called colts and females fillies.

Classification: The first domesticated horses were developed in Central Asia. They were small, lightweight, and stocky. In time, two general groups of horses emerged; the southerly Arab-Barb types and the northerly, so-called cold-blooded types. The modern breeds as: (a) the light, fast, spirited breeds typified by the modern Arabian, (b) the heavier, slower, and calmer working breeds typified by The Belgian and (c) the intermediate breeds typified by the Thoroughbred.

Color and Pattern: There are horses of a variety of colours and patterns, some highly variable and difficult to distinguish. Among the most important colours are black, bay, sorrel, chestnut, palomino, cream, and white.

Nutrition: The horse’s natural food is grass. For stabled horses, the diet is usually hay and grain. Oats are given especially to foals. Older horses, whose teeth are worn down, or those with digestive troubles, and be provided with crushed oats. Crushed barley is sometimes substituted in part for oats. Hay provides the bulk of the horse’s food. Mash is bran mixed with water and with various invigorating additions or medications. It may be given to horses with digestive troubles or eating problems. Corn is used as a fattening cereal. Salt is needed by the horse at all times and especially when shedding. Bread, carrots, and sugar are tidbits often used to reward an animal by the rider or trainer. In times of poverty horses have adapted to all sorts of food-potatoes, beans, green leaves, and in Iceland even fish. A number of commercial feed mixes are available to modern breeders and owners; these mixes contain minerals, vitamins, and other nutrients and given with hay.

Behavior: The horses’ nervous system is highly developed and gives proof to varying degrees of the essential faculties that are the basis of intelligence: instinct, memory, and judgment. Foals, which stand on their feet a short while after birth and are able to follow their mothers within a few hours, even at this even at this early stage in life exhibit the traits generally ascribed to horses. They have a tendency to flee danger. They express fear sometimes by showing panic and sometimes by immobility. Horses rarely attack and do so either when flight is impossible of when driven to assault a person who has treated them brutally.

Reproduction and development: The onset of adult sex characteristics generally begins at the age of 16 to 18 months. The horse is considered mature at approximately three years and adult at five. Fecundity may last beyond age 20 years with thoroughbreds and to 12 or 15 with other horses.  The gestation period is 11 months. A mare gives birth to one foal at a time, twins occasionally, and triplets rarely; the foal is weaned at six months.

Service Period: The useful life of a horse varies according to the amount of work it is required to do and the care taken by its owner. A horse that is trained carefully and slowly and is given the necessary time for development may be expected to serve to an older age than a horse that is rushed in its training. Racehorses that enter into races at the age of two rarely remain on the turf beyond eight. Well-kept riding horses, on the contrary, may be used more than 20 years.

Life Span: the life span of a horse is calculated at six to seven times the time necessary for his physical and mental development; that is, about 20 generally live longer than larger horses.

Conclusion: Horses are our great friends. So it is our duty to treat them kindly and take proper care of them.

Dog is a popular domestic animal all over the world.

The Dog 

Introduction: The dog is a popular domestic animal all over the world. The influence of dogs on the human society is immense. Dogs have played an important role in the history of human civilization and were among the first domesticated animals.

Physical Characteristics: The dog is a four-footed animal. Dogs can be of different sizes. Most of them are neither so big as a cow nor so small as a cat. Generally, it is the size of a goal. It has two eyes, two ears, a long face, and a short coiling tail. It has strong jaws. It has sharp teeth and claws. Its eyes are keen.

Wind dogs are very fierce. A dog wakes up at the slightest noise. It can run very fast. It was its tail to express its joy. Sometimes dogs go mad and bite men.

Food: Dogs are carnivorous animals. They love fish, flesh, and bone very much. They also cat other types of food such as bread, biscuit, rice, milk etc.

Usefulness: For more than 12,000 years, dog has lived with humans as a hunting companion, protector, object of scorn or adoration, and friend. Dogs are regarded differently in different parts of the world. Western civilization has given the relationship between human and dog great importance. Characteristics of loyalty, friendship, protectiveness, and affection have earned dogs an important position in Western society. In some areas of the world, dogs are used as guards or beasts of burden or even for food. In the United States and Europe, dogs are protected and admired. In ancient Egypt during the days of the pharaohs, dogs were considered to be sacred. They were important in hunter-gatherer societies as hunting allies and bodyguards against predators. When livestock were domesticated about 7,000 to 9,000 years ago, dogs served as herders and guardians of sheep, goats, and cattle. Although many still serve in these capacities, dogs are increasingly used for social purposes and companionship. Today, dogs are employed as guides for the blind and disabled. Dogs are specially trained and used for finding out narcotics, illegal arms and criminals by the police. Dogs are even used in therapy in nursing homes and hospitals to encourage patients toward recovery. Humans have bred a wide range of different dogs adapted to serve a variety of functions. This has been enhanced by improvements in veterinary care and animal husbandry.

The Breeds: There are approximately 400 separate breeds of purebred dogs worldwide.  A purebred dog is considered one whose genealogy is traceable for three generations within the same breed. National registries, such as the American Kennel Club in the United States, the Australian National kennel council, the Canadian Kennel Club, The Kennel Club of England, and studbooks on every dog in every breed registered in their respective countries. The Foxhound Kennel Stud Book, published in England in 1844, was one of the earliest registries. Other countries also have systems for registering purebred dogs. The AKC represents an enrollment of more than 36 million since its inception in 1884, and it registers approximately 1.25 million new dogs each year.


Conclusion: Dogs are great friends and companions for us. So, we should take proper care of them.
