Adelie Penguins


The Life of Animals | Adelie Penguins | There are 38 colonies of Adelie penguins, and more than 5 million Adélie in the Ross Sea region. Ross Island supports a colony of about half a million Adelie penguins. Adelie penguins breed from October to February, on the coast around the Antarctic continent. Adelie nests built of rough stones. Adelie penguins live in groups called colonies. These penguins are medium in size and weight of 46-75 cm (18-30 inches) long and 3.6 to 6 kg (7.9 to 13 pounds). The tail is a "little more than penguins queues. I am a bit "lower than other penguin species. His appearance is closer to the stereotypical image of penguins, like most black with a white belly. Adelie penguins can swim up to 45 mph (72 km / h) Adelie penguins are leopard seals prey, Skua and whales occasionally fatal.


Like all penguins, the Adelie highly social, feeding and nesting of groups. They are also very aggressive to other penguins who steal stones from their nest. Cherry-Garrard, said: "They are extraordinarily like children, of these people around the world, Antarctica, either as children or old men, full of self-importance. E 'was observed as the Penguin intrigue could put them in danger, Scott found a particularly troublesome The big problem with dog teams is due to the reckless behavior of penguins. These groups were jumping constantly in our iceberg. Since landing on your feet the whole attitude expressed devouring curiosity and a head of pork contempt for his own safety.


to the South Pole has been more receptive to this element of intrigue to Adelia Cherry-Garrard Meares and Dimitri-exercised dogs dog teams on the counter over, when we were stopped for a period of time. For stubborn personality characteristics Cherry-Garrard kept the bird in high esteemThe restriction of competition from these predators led to a surplus of krill, the penguins now used as a source of penguins fooddélie easier to reach their breeding grounds in October or November, in late winter and early spring. Nests consist of stones stacked.


In December, the warmest month in Antarctica (about -2 ° C or 28 ° F), parents take turns incubating the eggs, you'll eat and the other stays to warm the egg. The parent who is incubating does not eat. In March, young adults and their return to the sea. The Adelie penguin living on sea ice, but needs the ice-free land to breed. With the reduction of sea ice and food shortages, the population of Adelie penguins fell 65% in the last 25 years. Adelie penguins youth who have no experience in social interaction can respond to fake stimuli as penguins gather to breed.  Due to the emergence of birds and relatively similar to human behavior, human observers have interpreted this behavior as sexual deviation anthropomorphic.


The brochure, declined for publication in the official reports of the Scott expedition, said the frequency of sexual activity, an auto-erotic behavior, and the apparently anomalous behavior of men and women, young couples, including necrophilia, sexual coercion, sexual abuse and physical chicks and homosexual behavior, "says an analysis by William Russell and his colleagues Douglas Sladen and David Ainley. Levick observe Adelie penguins at Cape Adare, the site of the largest colony of Adelie penguins in the world. The discovery significantly clarifies the behavior of the species that some researchers believe it is an indicator of climate change Adelie penguins live in the area of the Ross Sea, Antarctica and the migration of an average of about 13,000 kilometers (8,100 miles) during the year that follows the sun from their breeding colonies of winter feeding areas and vice versa versa. Longer trips were recorded at 17,600 km (10,900 miles)

Swan

 

The Life of Animals | Swan | Swans are the largest members of the family Anatidae waterfowl, and are among the largest flying birds. The largest species, including swans, trumpeter swans and whooper swan, can reach a length of over 1.5 m (60 inches) and weighing over 15 kg (33 pounds). Species in the Northern Hemisphere swan have pure white plumage, but the species are mixed in the southern hemisphere in black and white. The Australian Black Swan (Cygnus atratus) is completely black except for white flight feathers on the wings, chicks black swans are light gray, and the South American Black-necked Swan has a black neck.


The legs of swans usually a dark gray black, with the exception of two species of South America's pink legs. Color varies from bill: the four subarctic species have black bills with varying amounts of yellow, and all others are modeled red and black. Four (or five) species occur in the northern hemisphere, is a species living in Australia and New Zealand and one species is distributed in southern South America. One species, the swan, was introduced in North America, Australia and New Zealand.


The Whooper Swan and Tundra Swan migratory birds as a whole, and trumpeter swans are almost completely migratory.There is some evidence that the black-necked swan is based on a portion of its range, but detailed studies have not known whether these movements are long or short-range migration Swans feed in the water and on land.


The average egg size (the swan) is 113 x 74 mm, weighing 340 g, a clutch size 4 to 7 and an incubation period of 34 to 45 days. Swans are known to aggressively protect their nests. A man was suspected to have drowned in such an attack The swan word comes from Old English swan, akin to the German Schwan and Dutch and Swedish SVAN Swan, in turn derived from Indo-European root * Swen (forthcoming, to sing). Young swans are known as cygnets or swanlings, the Greek κύκνος, Malia and Cygnus Latin word ("Swan") and the suffix-and Old French ("small").

Collie

 

The Life of Animals | Collie | Collies are typically medium-sized dog of about 10 to 25 kg (22 to 55 lb), with a slightly pointed snout and ears very erect or partially built up, a foxy impression. Types differ in color, used with the primary colors to black, black and brown, red, red and brown or black. The most common pattern in many types are black and white or tricolor (black and brown and white). Collies vary from Collie trainability "average" rough and smooth, maybe trainable of all breeds, the Border Collie. The Border Collie is the breed most need a job, while the rough collies, smooth and bearded lifestyleA fit better in the average working family member of a breed like the border collie is a dog full of energy and extremely agile with great stamina.


Dogs of collie type or derivation occupy four of the first sixteen degrees in Stanley Coren's The Intelligence of Dogs, the first border collie. These properties are usually strains of work suitable for agility, in addition to pastoral work, which is good for active sports such as sheepdog trials, flyball, disc dog and agility dog suitable. Collies compete in herding events. Collies herd instinct, which are essential can be trained to compete in herding trials. Some types of Collie (eg gross Collies, Smooth Collies, Shetland Sheepdogs and some strains of Border Collies and other breeds) have been shown for many generations as pets and bred for the sport of conformation, not as a shepherd dog.


The temperament of this breed is in literature, movies, TV shows and popular was described. Some breeds Collie (Rough and Smooth Collies in particular the collie) are affected by a genetic defect, a mutation in the MDR1 gene. Affected dogs show a cortisol concentration of lower than normal. The Association of the German Kennel Club (for the German Kennel Club) encourages breeding associations to test all cattle and prevent the breeding of affected dogs. Collies may have a genetic disease, dogs cyclic neutropenia, or gray collie syndrome.


Affected puppies rarely live more than 6 months old. Shepherd dogs of Collie-type have long been popular in Great Britain, and these can be regarded as a , from which a number of other local varieties, species and breeds have been formally derived, both in Britain and elsewhere.

Liger

 

The Life of Animals | Liger | Liger is the largest cat in the known world. Imprinted genes may be a factor that contributes to the great Liger. Other large hybrid cats can reach a similar size; litigon, a rare hybrid of a male lion and a female tiglon, about the same size as the liger, a male name Cubanacan (Alipore Zoo in India), reaching 363 kg (800 lbs) extreme rarity of these second-generation hybrids may make it difficult to determine if they are more or less, on average, than the Liger.


Male ligers also have the same levels of testosterone, on average, an adult male lion, but azoospermia according to Haldane's rule. In addition, female ligers can achieve great size, weighing about 320 kilograms (705 pounds) and reached 3.05 m (10 ft) long, on average, and are often fertile. Shasta, ligress (female liger) was born Hogle Zoo in Salt Lake City, May 14, 1948 and died in 1972 at age 24. 1973 Guinness World Records said the 18-year-old, 798 kg (lb 1759) to male life liger zoo in Bloemfontein, South Africa, in 1888 (not exactly like the zoo was opened in 1920), (c 'is a request Liger was 756 kg. and the year was actually 1953).


Fertility of female big cat hybrids is well documented in a number of different hybrids. This is in agreement with Haldane's rule: in hybrids of animals, sex is determined by sex chromosomes, if there is no sex, rare or sterile, is the heterogametic sex (the one with two different sex chromosomes eg X and Y) . Ligers tigers have as an alternative model, which is very weak and the lion as a reddish-brown background. In addition, they may inherit rosettes from the lion parent (lion cubs rosette and some adults retain faint markings).


White tigers have been crossed with lions to produce "white" (actually pale golden) ligers. In theory white tigers could be overcome with white lions to produce white ligers very clear, and even stripeless. There are ligers blacks. Like a blue or Maltese Tiger is probably no longer exists, gray or blue ligers are extremely unlikely. Several AZA zoos are reported to have ligers

Indri

 

The Life of Animals | Indri | In collaboration with the diadem Sifaka, Indri lemur is the largest still in existence. The Clinger and Indri is a vertical leaper and thus holds its body upright on a journey through the trees or branches of peace. Unlike any living lemur, the Indri has only a rudimentary tail. The silky fur is mostly black with white spots on the limbs, neck, crown, and lower back. Different populations of the species show large differences in color, with some populations of North consisting mainly or exclusively of black people. The face is pale with a black bare skin, and is sometimes trimmed with white fur.


Because of these color variations, Colin Groves listed two subspecies of Indri in 2005: the Indri Indri, the black part of its northern and relatively pale Indri indri variegatus in the southern part. Later editions of lemurs in Madagascar by Russell Mitter Meier et al. not to recognize this division, and recent work suggests that morphological and genetic variation in the Indri is clinal. The Indri practices long-term monogamy, seeking a new partner after the death of a partner. It lives in small groups, composed of male and female offspring mated and mature. In more fragmented forests of their range, the Indri live in large groups with several generations.


The Indri is sleeping in trees about 10-30 meters above the ground and used to sleeping alone or in pairs. It is a game for young indri common, sometimes grown women, too quiet, struggling somewhere between a few seconds to 15 minutes. Indri reach sexual maturity between the ages of 7-9. Females carry indri every two to three years, with a gestation period of 120-150 days


The Indri reaches sexual maturity between seven and nine years is a relatively slow speed, the indri known for its strong, distinctive songs, which can last from 45 seconds to 3 minutes more, well known. Song length and structure varies between and within groups, but most songs have the following three phases reason.


It is customary to coordinate this for two or more Indri, the time to get the notes to form a duo. Several groups used to sing one after the indri, react with each other. In addition to strengthening the contacts between groups, the songs can communicate and limits of territorial defense, environmental conditions, the reproductive potential of the group members, and warning signs The Indri after disturbances such as lightning , airplanes, birds and other calls of lemurs can sing.


Daily frequency of the song is at its peak during the breeding season of the indri from December to March. Several other Indri sounds were identified. The Indri emit a warning "cry" or "honk" on terrestrial predators such as the pit. To strengthen their song, the Indri to move up the tree before calling, which allows them to hear about 3-4 km wide.An Indri caught him and carried him to safety. Most legends establish a closer relationship between the Indri and humans. This brother was the first man and the brother who had remained in the forest, the first Indri. The Indri cries in mourning for his lost brother An explanation of the Babakoto name, is that the calls of the Indri was a father to his prodigal son demanded similar. When the son has also disappeared, the rest of the villagers ventured into the forest looking for two but he discovered that two large lemurs sitting in the trees: the first Indri. It is easy to see why the Indri is so closely identified with the people. Her long legs, body position upright large, the lack of a prominent tail, vocalizations and complex systems of communication are all reminiscent of human traits. Another feature of the Indri-human, as is its behavior in the sun. As his parents Sifaka, the Indri frequently engaged in what was for sunbathing or sun worship described.

Jack Russell Terrier

 

The Life of Animals | Jack Russell Terrier | Through its work, the nature, Jack Russell Terriers remain much as they were 200 years ago. The body length should be proportional to the amount, and the dog must present a compact, balanced image. A broken-coated dog, the longer on the tail or the face than what seen to be a smooth-coated dog, the skin can sometimes be a pattern of small black or brown spots, called the "tap", not the outside of the performed are low. Small V-shaped ears of moderate thickness are carried on the head when the dog is attentive, is not the point of the V on the outer corner of eye.


Because it is primarily a working terrier is the most important physical property of the size of the breast, not so large that it prevents the dog and working conditions in caves. The red fox is the traditional quarry of the Jack Russell Terrier, Jack Russell, the farm must be small enough to track. Red foxes vary in size, but (cm 30-36) around the world on average 13 to 17 pounds (5.9 to 7.7 kg) weight and an average chest circumference of 12-14 cm have the widest The Jack Russell Terrier and Parson Russell terrier breeds are similar because they have a common origin, but with some significant differences of the most striking is the range of the allowable amount.


The height of a Parson Russell on his shoulder, according to the breed standard is 12-14 cm (30-36 inches), so it is within the reach of the Jack Russell Terrier Club of America standard size for a Jack Russell of 10-15 cm ( 25-38 cm). However, the Parson Russell a show standards, while the Jack Russell standard is a general standard of work. The Russell Terrier, also called the English Jack Russell Terrier Jack Russell Terrier or short, is a generally smaller related species. Both the breed standards of the American Russell Terrier Club and the English Jack Russell Terrier Club Alliance says that at the withers, the ideal height of 12.8 inches (20-30 cm). Although sometimes the English or Irish Jack Russell Terrier, this is not the approved amount of Jack Russells in the UK.


According to the Jack Russell Club of Great Britain, the breed standard, it is the same size as the standard for Jack Russells in the United States, 10-15 inches (25-38 cm). Compared with the pastor, the Russell Terrier is always longer than the withers, while the pastor should be equally spaced points. The Fédération Cynologique Internationale standard for the Jack Russell terrier has given smaller size as a prerequisite. jack Russells are first and foremost a working terrier. Originally bred to blow foxes from their dens during the hunt, they are to a large number of bottom-dwelling quarry such as groundhog, badger and fox red and the gray.


By maintaining this type of working condition is for the most registered JRTCA / JRTCGB breeders Jack Russells tend to be very intelligent, athletic, fearless, and vocal dogs is essential. Obedience classes are also available for potential owners recommended, because Jack Russells stubborn and aggressive towards other animals and humans if not properly socialized Despite their small size, these dogs are not for condominium or apartment dwellers are recommended, unless the owner is willing to be the daunting task of the dog with the necessary amount of exercise and stimulation.


As an avid hunting dog, the Jack Russell usually follow most beings it encounters. This includes the skunk, and the breed is susceptible to toxic shock syndrome, which is absorbed in the chemical skunk spray from dogs and causes the red blood cell hemolysis, which can occasionally lead to fatal anemia and kidney failure skunk. Treatments available to flush the toxin to the dog.


Nipper was a dog born in 1884, which would probably be a dog, the Jack Russell Terrier. A Jack Russell named Bothy history in 1982 as part of the Trans-Globe Expedition. The possession of explorers Ranulph Fiennes and Ginny, he became the first dog to travel to both the North and South Poles. On 29 April 2007 rescued a Jack Russell named George five children at a carnival in New Zealand from an attack by two pit bulls.
