Rest in peace the national tribute sparrow. The goose body is camel's hooves, pale, the head is seven or eight feet high, the wings are more than one, the barley eats, its eggs are like urns, and its name is the ostrich.

—Guo Yigong Guangzhi "Tocharo.

In the first year of Yongzheng, a big bird, seven feet high, black, a foot camel, wings and walking, three hundred miles a day, can be iron, commonly known as an ostrich. —Tang Shu, Tocharian Biography. So the ostrich should be called the ostrich.

Eagle family. There are many types of animals, some are called eagles, some are called eagles, some are called eagles, kites, harriers, buzzards, eagles and so on. Eagles should be mostly called eagles.

Ancient people probably didn't know that there was such a species as penguins.

In ancient texts, eagles, ostriches, and penguins were called differently.

1.Eagle: Often referred to as "bird" or "bird of prey", such as "Soaring sharp-clawed raptor" in "The Book of Songs, Xiaoya, Caizhi".

2.Ostrich: There is no separate vocabulary for ostrich in ancient texts, but there are words such as "big eagle" or "big bird" to describe it, such as "big eagle, ostrich also" in "Erya Wing: Shi Bird".

3.Penguin: The word "penguin" does not appear in ancient documents, but there are words that describe its habits, such as "good at flying, can stand upside down, and cannot count a step", and there are also words and phrases that compare it with geese, such as "Penguin goose, black and white, its flight is also high, and its feet are short and thick, such as conewing".

These terms are often influenced by time and region, and the exact usage may vary depending on the literature and context.

A high point, a low point.

One is a bird and the other is a goose.

Taxonomic classification, they have the characteristics of birds: the body surface is covered with feathers, the forelimbs generally become wings (some species have vestigial wings), the bones are porous, and the interior is filled with gas; The heart has two atria and two ventricles. Constant body temperature.

In addition to the lungs, the respiratory organs also have air sacs formed by protruding from the lung walls to help the lungs breathe twice. Oviparous.

Creatures that meet these characteristics are birds, and they are not determined by whether they can fly or not. Many insects can fly, but they are not birds.

Ducks, penguins, ostriches belong to the category of birds, and bats do not belong to the category of birds.

Birds share some common features, such as: the body is covered with feathers; beak with no teeth; The forelimbs evolved into wings, which can mostly fly; Oviparous. Bone is hollow, healed, or very thin; In addition to the lungs, the respiratory organs have air sacs to assist breathing; keel protrusion in thorax; Constant body temperature, etc.

Although ducks, penguins, and ostriches have different appearances and different living habits, they all have the above characteristics, so they all belong to birds.

But bats are different. Bat body coat, not feathers; There is no beak and teeth in the mouth; Although the forelimbs also evolved into wings, they are featherless and only interphalangeal membranes; There are no air sacs to assist breathing; There is no keel protrusion in the thorax. In addition, bats are viviparous, and the larvae need to be fed by the mother after birth.

Bats are not birds, they are mammals, and they are the only mammals capable of flying.

Penguin (scientific name: Spheniscidae): The penguin, known as the "boat of the ocean", is one of the oldest migratory birds.

It lives mainly in the Southern Hemisphere and belongs to the order Penguin, the penguin family. characterized by the inability to fly; The feet are born in the lowest part of the body, so they are in an upright position; webbed between the toes; plantar (other birds land on their toes); forelimbs fin-shaped; The feathers are short to reduce friction and turbulence; A layer of air is retained between the feathers to keep them warm. The back is black and the belly is white.

The ostrich (scientific name: Struthio camelus) belongs to the ostrich family of the order Ostrichidae, and is one of the largest birds in the world, with adults up to 1 meter tall and male ostriches weighing up to 150 kg. The slender neck like a snake supports a small head, with a short, flattened, triangular mouth composed of several sheaths, the main feature is that the keel process is underdeveloped, unable to fly, and it is also the only two-toed bird in the world, with dangerous toenails about 7 cm long on each big toe of its feet, and its hind limbs are thick and powerful, suitable for running.

Penguins mainly live in the Southern Hemisphere, and there are 17 or 18 known species of penguins in the world, most of which are distributed in the Antarctic region, and there are also penguins in Cape Town, a tourist city in South Africa, on the hot African continent. Penguins feed on marine zooplankton, mainly Antarctic krill, and sometimes some brachiopods, squid, and small fish.

Ostriches live in the desert meadows and savanna regions of Africa. Ostriches eat a very mixed diet, but mainly on the stems, leaves, fruits, etc. of plants, especially flowering shrubs, parasitic creeping plants, ground creeping cucurbitaceae and wild figs, etc., and also eat insects, mollusks, small reptiles, birds and mammals, etc., while eating some sand grains to help digestion.

If it's the original, it hasn't evolved in any other place, it's mutated. Then I don't think ostriches, penguins can live in the forest. If it changes, then I will take it a grain of salt.

If you want a detailed explanation earlier, give me an email, I can't type %> here

Penguins can't because they're adapted to the alpine zone.
