Analysis: Chinese name: zebra finch Latin name: taeniopygia gutttata English name: zebra finch

Species classification: Chordates-> vertebrate subphylum-> Ornithischia-> Present-Birds-> Present-jaws->Passerines-> Ornithidae-> Plum Sparrows->

Range: Native to tropical forests in eastern Australia and New Guinea. China was introduced by Australia in the fifties of the twentieth century and is now an ornamental bird raised by many countries around the world.

Protection Level: Animal Profile: Alias: Zebra Grass Finch, Jinshan Pearl, Jinhua Bird, Jinhua Bird, Pearl Bird, Little Pearl, Brocade Finch.

The body length is 10 cm, the top of the male is blue-gray, the front of the eyes is grayish-white, there are brownish-red round spots on the back of the eyes, and most of the upper body feathers are brownish-gray; wing feathers black-brown, ribbed brownish-red with white pearly spots; The tail feathers are black with regular white horizontal stripes, and the tail end is rounded and spade-shaped; The throat and neck are pale gray with black horizontal stripes, and the chest and abdomen are earthy gray. The beak shell is vermilion, the toes are red, the female feathers are dull, and the head, cheeks, and throat are blue-gray; black longitudinal stripes under the eyes; upper body plumage pale grayish-brown; thorax and abdomen are pale gray; The red color of the beak shell is slightly lighter than that of the male, and the red of the toe is also lighter than that of the male.

Under the conditions of captivity, there are varieties with white plumage all over the body, and the white pearl bird male has a red beak and a female is light red. There are also varieties such as camel color, flower color, crown on the top of the head, and yellow mouth.

Habitat and habits: In the place of origin, it lives in the open area dominated by grasslands, shrubs and deserts, and is also seen near gardens and dwellings, foraging for plant seeds and shoots, and also eating a small number of small insects, inhabiting the woods, and liking to live in groups. When breeding, they still form a group of nests, after completing the nesting, there will be several mating behaviors within a week, and about a week after the successful pairing, 5 8 eggs are laid in the nest, the eggs are oval and white, and the two sexes hatch together to raise broods, and the male and female birds hatch alternately, but the female birds are dominant.

The incubation period is about 14 days. Birds that don't nurse still forage and frolic together.

The sound is soft, much like the "squeak" of a rapid wheel due to lack of fuel, and the sound of a small trumpet playing at a great distance when frightened and when calling each other is very similar to the sound of a small trumpet playing at a very long distance, and occasionally a "meow" sound similar to a cat's meow.

Animals are a large group of multicellular eukaryotic life forms called the kingdom Animalia. Generally, inorganic matter cannot be synthesized into organic matter, and can only feed on organic matter (plants, animals or microorganisms), so it has a different morphological structure and physiological function from plants to carry out life activities such as feeding, digestion, absorption, respiration, circulation, excretion, sensation, movement and reproduction. Classification of animalsZoology classifies animals with the same or similar characteristics according to the morphology, internal structure of the body, the characteristics of embryonic development, physiological habits, and the geographical environment in which they live.

It becomes two major groups of chordates and non-chordates. Animals can be divided into aquatic and terrestrial animals according to whether they are aquatic or terrestrial; Depending on whether they have feathers or not, they can be divided into feathered animals and those without feathers. In addition to the above two characteristics, we can also classify them with other characteristics.

There are also a variety of ways to classify animals. Through the dissection of different animals, it can be found that some animals have vertebrates in their bodies, and some animals do not have vertebrates in their bodies, and according to whether they have a spine in their bodies, we can divide all animals into two categories: vertebrates and invertebrates.

Note: Humans are also animals, and they are higher animals.

Animals are a large group of multicellular dads and vital signs, called the kingdom Animalia.

The ancestor of the panda is the first panda, the scientific name of the giant panda its Giant panda in eating (14 photos) is actually called "cat bear", meaning.

That is, "a bear like a cat", that is, "similar in essence to a bear, but similar in appearance to a cat." Strictly speaking, "panda" is the wrong noun. This is how this "wrongful conviction" was caused:

Before the liberation, the Beibei Museum in Chongqing, Sichuan Province once exhibited specimens of cats and bears, and the word "cat bear" was written horizontally from left to right on the explanation board. However, at that time, the horizontal headlines of newspapers and periodicals were used to read from right to left, so reporters misspelled "panda" as "panda" in their reports. The word "panda" has been widely disseminated, and it is difficult to correct it if you are used to it.

As a result, people had to make mistakes and call "pandas" "pandas". In fact, scientists named the giant panda "cat bear" because of its ancestors.
