What kind of bird is the first bird in the world to fly

Two Hypotheses of the Origin of Birds (2002-07-24 10:55 Sat.) The question of the origin of birds is one of the major scientific issues that the international scientific community has been concerned about. There are two major hypotheses popular in the international scientific community:

Birds are hypothesized by theropod dinosaurs;Non-dinosaur origin hypothesis. However, the theropod origin hypothesis has been rejected by the international scientific community.

In the nineties of the twentieth century, the world's first long-feathered dinosaur was discovered in Sihetun, northwest of Liaoning Province, China——— Chinese dragon bird. The discovery of the Chinese dragon bird has injected new vitality into the hypothesis of the "origin of theropod dinosaurs". In 1997, Dr. Ji Qiang, a researcher at the institute, discovered a second feathered dinosaur in western Liaoning——— primitive ancestral bird, whose tail feathers fully conform to the concept of modern bird feathers.

In 1998, Ji Qiang and others discovered the third dinosaur with long feathers——— tail feather bird in western Liaoning, whose tail feathers and "flying feathers" are completely consistent with the concept of modern bird feathers. These new scientific discoveries have generated powerful shockwaves internationally. The British journal Nature and the American National Geographic both published the research results of Ji Qiang and others in cover articles.

As a result of the results of Chinese research, more than 500 scientists overwhelmingly accepted the view that birds evolved from small carnivorous dinosaurs at the "International Symposium on the Origin and Early Origins of Birds" held at Yale University in the United States in 1999. They said, "The discovery of rare fossils such as the Chinese dragon bird in Liaoxi, China, is one of the most important scientific discoveries at the end of the 20th century, and is the most important event in the field of international life evolution research since Darwin proposed the theory of evolution."

Because the bird flies first.

Appearance characteristics.

Archaeopteryx is the ancestor of birds and lived in the Jurassic Age, about 155 million to 150 million years ago, so it is also rated as the world's earliest bird. These specimens are found only in Germany.

Archaeopteryx was about the medium size of today's birds, with wings that were rounded at the end and a tail that was longer than its size. Overall, Archaeopteryx can grow up to meters in length. Its plumage (for which there is less evidence than other features) is similar in structure and design to modern bird feathers.

But apart from some similar features to birds, it has many characteristics of theropod dinosaurs. Unlike today's birds, Archaeopteryx had tiny teeth that could be used to hunt insects and other tiny invertebrates. Archaeopteryx also had a bony tail and a three-toed claw on its feet, which closely resembled dinosaurs.

Because of its bird and dinosaur characteristics, Archaeopteryx is generally thought to be the link between them: probably the first creature to transform from a terrestrial creature to a bird. In the 1970s, John Ostrom suggested that birds evolved from theropod dinosaurs, and that Archaeopteryx is the most important evidence of this.

It retains some of the characteristics of birds, such as wishbones, feathers, wings. It also has some dinosaur features, such as a long ascending process of the talus, interdental plate, ischial process, small bones in the preorbital foramen on the top of the head, and a long herringbone tail. Ostrum also found that Archaeopteryx was significantly similar to Chisauridae.

The first remains of Archaeopteryx were discovered in 1862, two years after Darwin published On the Origin of Species. The discovery of Archaeopteryx seems to confirm Darwin's theory, and has since become important evidence of the relationship between dinosaurs and birds, transitional fossils, and evolution. In fact, further research on dinosaurs in the Gobi Desert and China has provided more evidence on the relationship between Archaeopteryx and dinosaurs, such as feathered dinosaurs.

Archaeopteryx is closer to the ancestors of modern birds because it has many bird characteristics; The extent of its divergence from the birds of the time is still questionable.

The ancestors of birds were born before our human ancestors.

Basically, all the birds that are noisy will destroy the wheel and fly, and only a few varieties of the letter will not fly.

Elephant ostriches can't fly anymore.

More than 90% of birds are able to fly.

The most flying bird in the world is an albatross.

Albatross is one of the most adept gliding birds. In windy climates, it can stay in the air for hours without flapping its extremely long, narrow wings. When there is no wind, it is difficult to lift its bulky body into the air and float on the water.

Like other birds, it can drink seawater. The most famous albatross is the black-browed albatross.

The distribution of albatross is very pronounced, which is related to the influence of wind in the ocean belt between Antarctica and South America, Africa and the southern tip of Australia. The largest concentrations of individuals and species are concentrated at latitudes 45-70°S, but they also breed in temperate waters of the southern hemisphere, while a few species have their distribution in the North Pacific. The Galapagos Islands and the Albatross of La Plata off the coast of Ecuador breed at the equator, where the climate is influenced by the cold Humboldt Current.

The habits of life of albatrosses

Albatross is nocturnal. Good at flying, swimming, and walking on land. They rest on the surface of the sea and are in the shore and islands during the breeding season.

Carnivorous, feeding on fish, mollusks, etc. They cannot catch prey while flying in the air, nor can they dive underwater to hunt for food, and foraging takes place on the surface. Alertness is high, solitary and quiet, active alone or in pairs.

The bobtail albatross can live up to 40-60 years. They can fly at sea for up to 5 years before returning to the land of the island where they were born. Pairing is lifelong, usually starting at the age of 6.

Return to the same place every year at the end of October to build their nests in sand, bush branches and volcanic rock. Each pair lays an egg, and the parents take turns to hatch the eggs, which hatch in about 65 days. At the end of May and the beginning of June, when the baby bird is almost grown, the parents abandon the nest and the bird.

The bird will quickly practice flying successfully on its own.
