Avian (bird) Birds usually with feathers, eggs animals have a high metabolism, so most birds can fly. Birds first appeared in the Jurassic period, the ancestor of birds, reptiles and creatures of what is in the paleontologists still controversial. Aves (aves) the world's existing 8,000 7 hundred species of birds, China has 1,183 kinds. The vast majority of arboreal life. Habitat minority camp life. Water birds foraging in the water, and some species are migratory habits. Mainly in tropical, subtropical and temperate. Domestic species distributed in Southwest, South, South, East China and North China. Birds surface is covered with feathers, forelimbs into wing side, with the ability to fly fast. There are airbags in the body; temperature is high and constant. Birds evolved from ancient reptiles came a live adaptation fly higher vertebrates. In addition to their morphological structure with many reptiles, there are also many differences. These differences on the one hand has made significant development on the basis of reptiles, reptiles than with a series of advanced features progressive. If the temperature is high and constant, perfect double loop system, well-developed nervous system and sense organs, and a variety of complex behaviors associated with this contact, etc.; hand flying life and have to adapt to more specialized, such as body streamlined, surface being feathers, forelimbs into wings special, bones strong, lightweight and many have together, with airbags. This series of specialized, so the birds have a strong ability to fly, to special flight movement. Because birds have in terms of form and structure a series of advanced features above, there are very strong ability to fly, flight movement can be performed quickly, so that a wide range of worldwide fish become second only to vertebrates outline. Birds known today is divided into two sub-classes, namely ancient birds and subclass Neornithes. Ancient Bird subclass to Archaeopteryx (archaeopteryx lithographica) as a representative. Neornithes including some fossil and extant since the Cretaceous birds, birds. Fossil Birds and Fishes head to head Hesperornis represented approximate their bones of modern birds, but on the jaw with a slot teeth. Existing Neornithes Head of birds can be grouped into three, namely: A flat chest Head The largest extant bird size (greater weight of 135kg, height 2.5m), suitable for running life. With a series of original features: Wings degradation, sternum non-keel, non pygostyle and tail sebaceous glands, feathers evenly distributed (no plume area and bare area of the points), barbs do not have feathers small hook (and therefore do not form pinna) , a well-developed male copulatory organ, toe tends to reduce life to adapt to running (2-3 toe). Limited distribution in the southern hemisphere (South Africa, the Americas and Australia). The overall aim flat chest famous representatives of ostrich (struthio camelus) also known as the African ostrich, there are other representatives of the American ostrich (rhea americana) and emu (or Australian ostrich) (dromaus nova-chollandeae). In addition, in New Zealand there are kiwi (apteryx oweni). Second, the Penguin Head , The large birds diving life, having a series of adaptation diving life characteristics. Fin-like forelimbs, suitable for paddling. With scaly feathers (rachis short and wide, narrow pinna), evenly distributed on the body surface. Short tail. Move to the rear of the body and short legs, webbed toes, adapt swimming life. Body nearly vertical when walking on land, swing around. Developed subcutaneous fat, help in cold areas and water to maintain body temperature. Heavy bones without inflated. Sternum has developed keel, which is related to the water front legs. Swim fast, it was known as "underwater flight." Limited distribution in the southern hemisphere. The overall aim is king penguin penguins representatives (aptenodytes patagonicus). Third, sudden chest Head Sudden chest Head of birds, including the vast majority of the existing distribution throughout the world, a total of about 35 projects, more than 8500 kinds. Their common features are: wing developed, good flying, sternum with a keel. Last 4 to 6 tailbone to heal into a pygostyle. With inflatable skeletal. Pennaceous developed, constitute pinna, feather body surface area, bare area of the points. The vast majority are not mating with the male organ. Sudden chest Head of birds produced in our country, namely, 81 families and 26 orders. According to their way of life and structural characteristics, can be divided into six ecological groups, namely Natatores, waders, raptors, climbing birds, terrestrial birds and songbirds. Including: 1, loons head 2, Yuan ruficollis head 3, Procellariiformes 4, Pelecaniformes 5, Ciconiiformes 6, Anseriformes 7, Falconiformes 8, Galliformes 9, Gruiformes 10 Charadriiformes 11, dove-shaped head 12, Psittaciformes 13, Juan shaped head 14, Strigiformes 15, Nighthawk head 16, Swift mesh 17, mice birds eye 18, quetzal head 19 Coraciiformes 20, Piciformes 21, passerine Aves on taxonomy is a sub-sects of vertebrate classes. (Figure: brown-eared pheasant) Birds are the main features: Most fly life. Surface coated feathers, forelimbs became general wing (wing some species degradation), bony voids inside the inflatable body; heart has two atria and two ventricles. Body temperature constant. A lung respiratory organs other, there are formed projecting from the wall of the pulmonary air bag, to help double breathing lungs. Oviparous. Birds are bipedal, temperature, oviparous vertebrates, wearing feathers, forelimbs evolved into wings, have a hard beak. Bird's body sizes, both small hummingbirds have huge ostrich and emu (produced in Australia, a large flightless bird figure). A wide variety of birds, global distribution, ecological diversity, and now the birds can be divided into three Head. Head flat chest, including a class can not be good to go flightless birds such as ostriches. Penguin Head, including a class can not be good for swimming and diving and flying birds, such as penguins. Sudden chest Head, including the wings of a bird can fly well developed, the vast majority of birds belonging to the Head. Currently the world's known bird, a total of 9,000 kinds of optical recording 1,300 on a variety of Chinese, many of whom are Chinese endemic bird species (see the list of bird species endemic to China). There are about 120-130 species of birds have become extinct, compared with other terrestrial vertebrates, birds have a unique physical characteristics of many different types. Bird food variety, including nectar, seeds, insects, fish, carrion, or other birds. Most birds are daytime activities, there are some birds (such as owls) are active at night or dusk. Many birds will migrate over long distances in order to find the best habitat (such as the Arctic tern), there are also some birds spend most of their time at sea (eg albatross). Most birds are flying, a few ratites not fly, especially those living in the island's birds, basically lost the ability to fly. Flightless birds, including penguins, ostrich, kiwi (a kind of kiwi from New Zealand), and extinction of the dodo. When humans or other mammals intrusion into their habitat, these birds can not fly more vulnerable to extinction, such as large sea birds, and New Zealand moa. (BC 414) is one of the masterpieces of Aristophanes' Birds, "is the only extant mythological fantasy theme of comedy. There are two play together in Athens and the flock of birds between heaven and earth created a "cloud wood pigeon partridge country." This country is an ideal society in which there is no distinction between rich and poor, without exploitation, labor is the only condition for survival. Comedy satire parasitic life in the city of Athens, is the oldest in the history of European literature describing the ideal society works. In artistic terms, "bird" is undoubtedly the most outstanding works of Aristophanes. Colorful drama plot, between the chorus plays out forest birds, colored flowers. The play fanciful, lyrical atmosphere. In Aristophanes's plays, the most complete comedy structure. In nature, birds are the most beautiful of all vertebrates, shape, sound most sweet, much-loved animal. From the frozen poles to the roof of the world, from the tumultuous waves of the ocean brave, to lush jungles, from barren deserts to the densely populated city, almost all traces of birds. Birds are flying in the air to adapt to a class of higher vertebrates, is composed of a reptile evolved. Now the earliest known bird is Archaeopteryx, 1861 in southern Germany discovered the first Archaeopteryx fossils. Archaeopteryx has both the characteristics of birds and reptiles have some similarities, it is evidence of the evolution of birds from the reptiles of a strong come. Birds are born with feathers body, the body is streamlined, the forelimb become wings, the hind legs to support the weight of the feet, except for a very few species can fly. Bird's beak mouth is called, since the beak feeding in the soil, generally narrow tapering beak, mouth no teeth. Birds are warm-blooded animals, high body temperature, usually 42 ℃. There are well-developed keel on the sternum of birds, inflatable hollow bones, which are adapted to the bone structure of the birds flying life. Many species of birds, fish, second only in vertebrates. Now the world's known species of birds, more than 9000, China has 1,186 kinds. These birds in size, shape, color and other aspects of living habits, there are significant differences. In so many birds, the largest number of ostriches, it is a bird in the "giant." African ostrich body 2.75 meters high, the heaviest up 165.5 kg. South America's smallest hummingbird, only 50 mm in length and weighing it as heavy as the same coin. Birds can fly, but not all birds can fly. Such as ostrich wings degraded, sternum small and flat, no keel, can not fly. Penguin is a specialized seabirds, wings became flippers, lost the ability to fly. Although some birds can fly, but the flight is very short distance, such as chicken wings due to the short, can not fly. Most birds have a strong ability to fly. In flying birds, vultures flying to calculate the maximum flying height of 9,000 meters. Flight fastest goshawk, short-distance flight fastest speeds of up to 600 kilometers. The longest flight distance is terns can fly far away from the Antarctic Arctic, travel about 1.76 million meters. Birds metabolism, digestion and strong, so the birds eat quite large, such as hummingbird nectar amount equal to the weight of the day smoking doubled. Some small birds daily food amount corresponding to 10% to 30% by weight. Most birds are omnivorous, and do not pick and choose. Every spring and fall, the birds are in droves, blotting out the sun to fly in the sky, which in different seasons to replace the habitat area, or move from winter nesting ground, or to return from wintering grounds seasonal nesting phenomenon known as bird migration. Annual return of the spring, the birds began to make a series of activities in courtship, reproduction, nesting, incubation and brooding like. Most of birds The smallest birds and bird eggs smallest hummingbird many people know that the world's smallest bird, in fact, this argument is not very accurate, because hummingbirds around the world there are about 315 kinds, distributed in North America from Alaska to South America The Strait of Magellan, and on many islands in between. They are also great differences in shape, the largest bird body up to 21.5 cm Wasp, of course, can not say that it is the world's smallest bird. And produced in the bee hummingbird of Cuba is only 5.6 cm in length, which accounts for about half of the beak and tail and weighing only about 2 grams, about the same size and bees, hummingbirds like shape is the world's smallest bird, its eggs is also the world's smallest bird eggs, not much bigger than a full stop. Most hummingbird feathers very bright and shining metallic luster. Their superb flying skills that can fly backwards, VTOL, the frequency of vibration of wings rapidly, up to 50 to 70 times per second, so the "Bird", "comet", "forest goddess" and "Corolla" and other title. There are many places in China in recent years have claimed to have found a hummingbird, they are actually misinformation. (Note 2) The largest extant bird body shape is the world's largest bird living in Africa and the Arab region in Africa ostrich, it's up to 2 to 3 meters tall, weighing about 56 kg, the heaviest of up to 75 kg. But it can not fly. It weighs about 1.5 kg of egg, 17.8 cm long, 30-40 is approximately equal to the total weight of the eggs, the eggs are now the largest bird. Widest wingspan bird wandering albatross, 3.63 m. The largest birds living in southeastern Africa Curley birds, wing length 2.56 m, weighing about 18 kg, the weight of the largest birds in the world who can fly. Great Bustard heaviest birds, male weighing 18 kg. Borneo's smallest bird of prey falcon, body length 15 cm, weight 35 grams. (Note 1) Up swan feathers of birds, more than 25,000. Hummingbird feathers minimal, less than 1000. Big bird paradise feathers longest Li Juan, tail is more than 2 times the body length. The longest life expectancy in the longevity of birds Birds lot of large seabirds such as albatrosses average life expectancy is 50 to 60 years, a large parrots can live to around 100 years. In Liverpool there is a man named "Jamie" Amazon parrot, was born Dec. 3, 1870, died Nov. 5, 1975, at the age of 104 years old, is worthy of birds "old birthday." Banding longest life king albatross seabirds, 60 years. Longest life caged birds crested Cockatoo, 80 years. The fastest flying bird drywall Swift usual flying speed of 170 km / h, the fastest time of up to 352.5 km / h, called the fastest flying birds. Peregrine falcon sprint fastest bird in the dive to catch prey is able to reach 180 km / h. Europe's fastest birds in level flight Eider, 76 km / h. Birds fly slowest snipe hill, 8 km / h. The highest frequency of bird wings hummingbird angle, 90 times / sec. Bird flapping frequency of the slowest large vulture, gliding hours without flapping. A flight of birds in North America's longest golden plover, to 90 km / h speed to fly 35 hours, more than 2,000 kilometers across the sea. The highest flying birds, whooper swans and Gyps vulture is the highest flying birds, flying over the roof of the world can - Mount Everest at an altitude of 9,000 meters or more, otherwise it may hit killed on steep ice cliffs. Birds fly the farthest is the Arctic tern birds fly the farthest. It is a medium body bird, accustomed to life over the day, they were known as "the day the birds." When night falls, when the Antarctic, the Arctic will be flying far, because the polar opposite of day and night, when the North Pole is just daylight. June each year in the Arctic, "parenthood", it led to the August "children" to the south migratory flight route runs through the Earth to reach the vicinity of the South Pole in December, has been stayed until the beginning of March the following year, then northbound again. Arctic terns each year travel between the poles, the flight distance of over 40,000 kilometers. Because it always lives in the sun does not _set_ the place, the people, also known as its "day birds." The fastest swimming bird Papua penguins, 27.4 km / h. Fastest bird ostrich, 72 km / h. The most ferocious birds living in the Andes of South America between cliffs Andean condor, the body length of up to 1.2 meters, two wings expand up to 3 meters. It has a strong and "beak" and sharp claws curved hook, designed to eat live animals, not just eat deer, sheep, rabbits and other small animals, and even cougars and other large predatory mammals, so there. " Birds eat the lion "and" king of birds "in the title. Japan's longest tail feathers of birds with artificial hybridization developed into a long-tailed chicken, tail length is very alarming, generally up to 6 to 7 meters long, the longest recorded for the 1974 bred one, is 12.5 meters. If it stood on the balcony of the four-story building on its tail on the ground floor you can always drag the ground, and therefore the world's longest bird feathers. Male and female weight difference largest bird living in the Great Bustard in northern Eurasia male and female birds maximum weight difference, the male weighing 11 to 12 kg, while females only 5 to 6 kg . Mouth peak longest bird life in South America is the mouth peak toucan bird longest length of its mouth is about one meter peak, very strange. Australia's longest beak pelican, long 47 cm. The most wide beak Shoebill, width of 12 centimeters. Most African gray parrot birds learn words, learn more than 800 words. Ming had been masters of long-term wetland reed warbler birds, 60 kinds of birds to imitate. Africa's most complex woven nest bird's nest, it is also the largest public nests, there are more than 300 nests room. Bald Eagle Nest largest nest, six meters long and 2.9 meters wide. The smallest nest bee hummingbird's nest, only the size of a thimble. Minimum spawning albatross birds produce only an egg each year, is the least of the birds lay eggs. Maximum number of birds nest egg gray partridge, 15 to 19 per litter. The longest incubation period incubation period is also the longest bird albatross birds generally require 75 to 82 days. Latest albatross chicks sexually mature birds reach sexual maturity process is also the longest of birds, you need 9 to 12 years. The largest fossil bird eggs before the middle of the 17th century, in the south of the island of Madagascar live like a bird, now extinct. Elephant bird egg fossils diameter is 35.6 cm, equivalent to the size of 148 eggs, is the largest bird eggs fossils found so far in the world. Largest bird fossils largest bird fossils Silom bird fossils, it is estimated up to about five meters tall, had lived in the island of Madagascar, extinct in the 7th century. Protection of Birds is to protect the environment Constitute an important part of forest vegetation of the earth, many organisms to earning numerous woodland Yan, the birds are among the most important members. Here, plants are producers, various Queensland Some insects and plant-eating mammals consumers, birds on the one hand as a consumer Who participated in the activities of forest ecology, on the other hand to suppress the damaging effects on plants Creatures. Woodlands provide habitat for birds, and bird protection of normal plants Long, they are different in different aspects of the food chain to become a forest ecosystem Backbone. Our ancestors deeply understand the meaning of love birds, although written records various levels of detail, but Ages ancient times without a break. Oracle has the word like a woodpecker pecking a worm-like, and appeared in Bu Speech, so that the birds have a pest of Italy, China's ancient value of this bird is very clear. Into the hole Midnight, he made clear thinking "nest egg is destroyed Xiang Phoenix is not" protected birds Think. "Book of Rites kingship chapter," states: "Do not fawn no eggs, no kill tires, no killings, no Nest, "and that hunting deer and destroyed the nest eggs are not allowed to dig." Huainan " There are documented hunting off the moratorium, with particular emphasis shall deforestation and burning in a particular season Field in order to protect the chicks. After each dynasty has emphasized the government's decree to protect birds and other Animals, to the establishment of the People's Republic has introduced a number of protected birds and their Its wildlife laws and regulations, and the development of relevant laws.

Brief introduction
Bird (Bird Class) Birds usually with feathers, egg-laying animals, have a high metabolic rate, long bones are mostly hollow, so most birds can fly. Birds first appeared in the Jurassic period, the ancestor of birds, reptiles and creatures of what is in the paleontologists still controversial. The earliest birds appeared about 1.5 billion years ago. Their bodies were fusiform, forelimbs into special wing feathers surface, the temperature is constant, developed chest muscle, bone healing, thin, hollow, brain is more developed. There may be a double balloon breathing, body mass can be reduced bladder. These physical characteristics are adapted to fly.

Evolution
Archaeopteryx recovery plan Birds evolved from ancient reptiles came a live adaptation fly higher vertebrates. In addition to their morphological structure with many reptiles, there are also many differences. These differences on the one hand has made significant development on the basis of reptiles, reptiles than with a series of advanced features progressive. If the temperature is high and constant, perfect double loop system, well-developed nervous system and sense organs, and a variety of complex behaviors associated with this contact, etc.; hand flying life and have to adapt to more specialized, such as body streamlined, surface being feathers, forelimbs into wings special, bones strong, lightweight and more than a combined, with a balloon and lungs, the air bag is a supply of birds in flight have enough oxygen in the structure. Contraction and expansion of the balloon with the wing motor coordination. Wings raised, balloon dilatation, a part of the outside air into the lungs where gas exchange. Also most of the air directly through the lung rapidly into the airbag, the gas exchange is not carried out, the airbag put large number of oxygen-containing air is temporarily stored. Drooping wings, contracted airbag, the airbag in the air again through the lung for gas exchange, and finally excreted. Thus, birds every breath of air in the lungs twice gas exchange, can be seen no effect of gas exchange balloon, its function is to store the air assist complete lung respiration. There airbags reduce the proportion of the body, emitting heat, regulate body temperature and so on. This series of specialized, so the birds have a strong ability to fly, to special flight movement.

Classification
Birds known today is divided into two sub-classes, namely ancient birds and subclass Neornithes. Ancient Bird subclass to Archaeopteryx (Archaeopteryx lithographica) as a representative. Neornithes including some fossil and extant since the Cretaceous birds, birds. Fossil Birds and Fishes head to head Hesperornis represented approximate their bones of modern birds, but on the jaw with a slot teeth. Existing Neornithes Head of birds can be grouped into three, namely: A flat chest Head The largest extant bird size (greater weight of 135kg, height 2.5m), suitable for running life. With a series of original features: Wings degradation, sternum non-keel, non pygostyle and tail sebaceous glands, feathers evenly distributed (no plume area and bare area of the points), barbs do not have feathers small hook (and therefore do not form pinna) , a well-developed male copulatory organ, toe tends to reduce life to adapt to running (2-3 toe). Limited distribution in the southern hemisphere (South Africa, the Americas and Australia). The overall aim flat chest famous representatives of ostrich (Struthio camelus) also known as the African ostrich, there are other representatives of the American ostrich (Rhea americana) and emu (or Australian ostrich) (Dromaus nova-chollandeae). In addition, in New Zealand there are kiwi (Apteryx oweni). Second, the Penguin Head , The large birds diving life, having a series of adaptation diving life characteristics. Fin-like forelimbs, suitable for paddling. With scaly feathers (rachis short and wide, narrow pinna), evenly distributed on the body surface. Short tail. Move to the rear of the body and short legs, webbed toes, adapt swimming life. Body nearly vertical when walking on land, swing around. Developed subcutaneous fat, help in cold areas and water to maintain body temperature. Heavy bones without inflated. Sternum has developed keel, which is related to the water front legs. Swim fast, it was known as "underwater flight." Limited distribution in the southern hemisphere. The overall aim is king penguin penguins representatives (Aptenodytes patagonicus). Third, sudden chest Head Sudden chest Head of birds, including the vast majority of the existing distribution throughout the world, a total of about 35 projects, more than 8500 kinds. Their common features are: wing developed, good flying, sternum with a keel. Last 4 to 6 tailbone to heal into a pygostyle. With inflatable skeletal. Pennaceous developed, constitute pinna, feather body surface area, bare area of the points. The vast majority are not mating with the male organ.

Our species
Sudden chest Head of birds produced in our country, namely, 81 families and 26 orders. According to their way of life and structural characteristics, can be divided into six ecological groups, namely Natatores, waders, raptors, climbing birds, terrestrial birds and songbirds. Including: Blue Peacock 1, loons head 2, Grebe head 3, Procellariiformes 4, Pelecaniformes 5, Ciconiiformes 6, Anseriformes 7, Falconiformes 8, Galliformes 9, Gruiformes 10 Charadriiformes 11, dove-shaped head 12, Psittaciformes 13, Juan shaped head Gallus 14, Strigiformes 15, Nighthawk head 16, Swift mesh 17, mice birds eye 18, quetzal head 19 Coraciiformes 20, Piciformes 21, passerine Aves on taxonomy is a sub-sects of vertebrate classes.

Feature
Birds are the main features: Most fly life. Surface coated feathers, forelimbs became general wing (wing some species degradation), bony voids inside the inflatable body; heart has two atria and two ventricles. Body temperature constant. A lung respiratory organs other, there are formed projecting from the wall of the pulmonary air bag, to help double breathing lungs. Oviparous. Birds are bipedal, temperature, oviparous vertebrates, wearing feathers, forelimbs evolved into wings, have a hard beak. Bird's body sizes, both small hummingbirds have huge ostrich and emu (produced in Australia, a large flightless bird figure). A wide variety of birds, global distribution, ecological diversity, and now the birds can be divided into three Head. Head flat chest, including a class can not be good to go flightless birds such as ostriches. Penguin Head, including a class can not be good for swimming and diving and flying birds, such as penguins. Sudden chest Head, including the wings of a bird can fly well developed, the vast majority of birds belonging to the Head. Currently known worldwide, a total of more than 9000 kinds of birds, the light on the record has more than 1300 kinds of Chinese, many of whom are Chinese endemic bird species (see the list of bird species endemic to China). There are about 120-130 species of birds have become extinct, compared with other terrestrial vertebrates, birds have a unique physical characteristics of many different types. Bird food variety, including nectar, seeds, insects, fish, carrion, or other birds. Most birds are daytime activities, there are some birds (such as owls) are active at night or dusk. Many birds will migrate over long distances in order to find the best habitat (such as the Arctic tern), there are also some birds spend most of their time at sea (eg albatross). Most birds are flying, a few ratites not fly, especially those living in the island's birds, basically lost the ability to fly. Flightless birds, including penguins, ostrich, kiwi (a kind of kiwi from New Zealand), and extinction of the dodo. When humans or other mammals intrusion into their habitat, these birds can not fly more vulnerable to extinction, such as large sea birds, and New Zealand moa.

Most of birds
Smallest bird and the smallest bird eggs Many people know that the hummingbird is the smallest bird in the world, in fact, this argument is not very accurate, because hummingbirds around the world there are about 315 kinds, distributed in North America from Alaska to the Strait of Magellan in South America, as well as during the many island.
