The most birds in the world
The fastest bird: ostrich
The fastest bird to swim: Papua penguin
The smallest bird and the smallest bird's egg: Many people know that hummingbirds are the smallest birds in the world, but this statement is not very accurate, because there are about 365,438+05 species of hummingbirds in the world, which are distributed from Alaska in North America to strait of magellan in South America and many islands in the middle. Their bodies are also very different. The largest hummingbird is 2 1.5 cm long, but it can't be said to be the smallest bird in the world. The African wheat grain bird is only 5.6 cm long, of which the beak and tail account for about half, and the weight is only about 2 grams, which is about the size of a honey bug. This hummingbird is the smallest bird in the world, and its egg is also the smallest bird's egg in the world, not much bigger than a full stop. Hummingbirds' feathers are mostly bright and metallic. Their flying skills are superb, they can fly upside down, take off and land vertically, and their wings vibrate very fast, up to 50 ~ 70 times per second, so they are called "God Birds", "Comets", "Goddess of the Forest" and "Corolla". In recent years, many places in China have claimed to have found hummingbirds, but they are all misinformed.
The largest bird: African ostrich, whose egg weight is about 1.5 kg and its length is about 17.8 cm, which is about equal to the total weight of 30~40 eggs. It is the largest bird egg at present.

Longest-lived bird: There are many long-lived birds. For example, the average life span of large seabird albatross is 50-60 years old, and large parrot can live to about 100 years old. There is an Amazon parrot named Jamie in Liverpool, England. Born in1870,65438+February 3rd, died in 1975,165438+1October 5th, at the age of 104. It is worthy of being the "longevity star" among birds.
Wang Albatross, the longest-lived ringed seabird, lived for more than 60 years.

The bird that lays the most eggs: grey partridge (a kind of chicken)
Birds with the longest incubation period: Albatrosses are also birds with the longest incubation period.
Birds with the latest sexual maturity: Albatross chicks also have the longest sexual maturity process.
The largest bird egg fossil:1Before the middle of the 7th century, there was an elephant bird in life in south, Madagascar, which is now extinct. This is by far the largest bird egg fossil found in the world.
The largest bird fossil: The largest bird fossil is dinosaur fossil.
The origin of birds
The research on the origin of birds has gone through several stages.
1868, Huxley put forward the hypothesis that birds originated from dinosaurs. Huxley is a famous British biologist and a staunch supporter of Darwin's theory of evolution. At the same time, he was also the first scholar to put forward the theory that birds originated from dinosaurs.
1927, Danish paleontologist Hailmann published a very classic book "The Origin of Birds" in his 1927, in which he pointed out that although birds and dinosaurs are very similar, dinosaurs have been very specialized, so birds may not have originated directly from dinosaurs, but have a * * * ancestor with dinosaurs, that is, teeth. The so-called Serrat is a more primitive fossil group than dinosaurs. This group is considered as a large group, which has produced some major modern vertebrates, such as dinosaurs, birds and crocodiles. It may have appeared earlier than Jurassic and Cretaceous in Triassic. This theory has been popular for about half a century since it was put forward.
From 1973 to 1985, the theory of dinosaur origin revived again. When studying vertebrate fossils, scholars found that a fossil identified as pterosaur had feathers, and then another archaeopteryx fossil was discovered. This accidental discovery made scholars associate the relationship between birds and dinosaurs. Since 1986, the theory of dinosaur origin has been prevailing, and more and more fossil evidence supports this hypothesis.
Restoration of sauropod dinosaurs: hairy dinosaurs from China. For example, sauropods are the first dinosaur fossils with truly bifurcated feathers. The discovery of this fossil has caused a great sensation in the field of paleontology in the world, and it is considered as the most important and latest evidence of the theory that birds originated from dinosaurs. Some scholars even suggested that dinosaurs were not extinct, and all the living birds we saw were dinosaurs. Hummingbirds living in South America naturally became the smallest dinosaurs.
The origin of birds is a complicated problem. When more evidence is found, there may be other explanations (it is generally believed that the Chinese dragon bird is the earliest ancestor of birds).
