Rooster does not belong to birds

Today, the sky is clear and the air is fresh. My dear mother and I are laughing and talking to the favorite home.

Stepping into the door of the favorite home, a group of cock-like cocks like a big general smashed up together, as if instead of the owner actively and enthusiastically greeted the guests coming from afar. The appearance of the "Grand General" is beautiful outside. Hey, it is dressed in a beautiful "bringing gown", it seems like a cockscomb that has been burned by a male fire. Under the bright sunshine, the red crown is more dazzling and obvious. "Wow, it's beautiful." "" I am full of praise. However, the problem suddenly appeared in my mind. Why is the chicken so like a bird, is it a bird? I was so anxious that I didn't have any chance to play.

With this puzzling problem, I checked the information online. This is because people often regard "flying" as the characteristics of birds. Although some birds do not fly, and "flying" is not just a bird's character. Because many insects can fly, but because most birds will fly, the "flying" feature becomes a typical feature of the concept of birds. Chicken belongs to the chordate door - vertebrate sub-avian - avian - chest - head - Chicken-shaped chickens are the most common poultry raised by humans. The chickens are derived from wild chickens and have been domesticated for at least 4,000 years, but it was not until 1800 that chickens and eggs became mass-produced goods.

The original chicken is one of the genus of the genus Chicken. Also known as Camellia Chicken. It is the ancestor of the chicken, and is now produced in Yunnan, Guangxi Zhuang Autonomous Region and Hainan Province. Southeast Asia, India, the Malay Peninsula and Indonesia's Sumatra are also distributed. The original chicken body is similar to the chicken. The head has a meat crown and a pair of fleshy sides on the throat side, which is a unique feature of the genus. Male and female. The male feather color is very similar to that of a domestic cock. The most striking difference is that the feathers of the head and neck are narrow and pointed, the front is dark red, and the back is golden yellow. These narrow long feathers extend from the neck back and cover the front of the back, which is more gorgeous than the chicken. The tail feathers and the overlying feathers are black, with metallic green reflections, and the feather base is white, especially when flying. Females are similar to domestic hens, with smaller males and shorter tails. The head and neck are dark brown and red; the neck feather is also extra long, and the shaft is black and brown with a golden plume. In the dense forests of tropical and subtropical mountains, often planting seeds, buds, grains, etc., and eating insects and other small animals. The nest camp is slightly recessed on the ground, covered with fallen leaves and weeds. Spawning begins in southern Yunnan in February, with high tides from March to May and some continuing through October. Not only chickens are birds, but our ducks and geese are all birds. However, in the long-term domestication of human beings, they have lost the ability to fly and, depending on the needs, have produced many sub-species, hens, cockfighting chickens, long-tailed ornamental chickens, etc. .
