What are pigeons, parrots, flies, sparrows collectively called organisms?

Pigeons, parrots, flies, and sparrows are collectively called birds.

Aves is a class of the subphylum Vertebrata. All are feathered, warm-blooded, oviparous, and have an amnion outside the embryo. The forelimbs are wings, which sometimes degenerate. Most of them live in flight. The heart has two atria and two ventricles. Only the right aortic arch is preserved, and the left aortic arch is degenerate.

Bones have many pores filled with gas. In addition to the lungs, the respiratory organs also have air sacs to assist breathing. Birds in my country are divided into six categories: swimming birds, wading birds, climbing birds, land birds, birds of prey, and songbirds. These six categories are collectively referred to as the six major ecological groups of birds.

Additional information:

1. Appearance characteristics

Aves are all feathered, warm-blooded, oviparous, and have amniotic membranes outside the embryo. The forelimbs are wings, which sometimes degenerate. Most of them live in flight. The heart has two atria and two ventricles. The bones are mostly cavities filled with gas.

In addition to the lungs, the respiratory organs have air sacs to assist breathing. Its main characteristics are that the whole body is covered with feathers, the forelimbs have become wings, and it can fly in the air; the body temperature is constant and high, reaching 40℃. To adapt to flying, the skeleton has become lighter.

2. Origin of Birds

The study of the origin of birds has gone through the following main stages.

In 1868, Huxley proposed the hypothesis that birds originated from dinosaurs. Huxley was a famous British biologist and a staunch supporter of Darwin's theory of evolution. He was also the first scholar to propose the theory that birds originated from dinosaurs.

In 1927, Danish paleontologist Hermann published a very classic book "The Origin of Birds" in which he proposed that although birds and dinosaurs are very similar, because dinosaurs are already very specialized, birds may not originate directly from dinosaurs, but rather have a common ancestor with dinosaurs, which is the theodonts.

The so-called theodonts are a group of fossils that are more primitive than dinosaurs. This group is believed to be the largest group that gave rise to some major modern vertebrates, such as dinosaurs, birds, and crocodiles. It may have appeared earlier, in the Triassic period, which is earlier than the Jurassic and Cretaceous periods. This theory has been popular for about half a century since it was proposed.

If you must add flies, then it can only be collectively called "eumetazoa", as opposed to protozoa and primitive metazoa. Flies are even protostomes, not deuterostomes.

If it is not a fly, it is a goshawk. Then it should be classified into the class of Aves, the order of the modern jaws (the order of protoceratops) in the subclass of the modern birds.

Wow, this question is too professional. I don't know if the answer is correct. In terms of calcium content, the order should be mandarin fish = hairtail, yellow croaker, pomfret, crucian carp, bream. Why? Because judging from their eating habits, carnivorous ones should be stronger than omnivorous ones, hehe.
