The complete collection of ancient poems describing birds is as follows:
1. Poems
1. Two orioles sing in the green willows, and a line of egrets ascends to the blue sky. The window contains the snow of the Xiling Mountains for thousands of years, and the door is docked with a ship thousands of miles away from the Eastern Wu Dynasty; hundreds of chirps and thousands of sounds move at will, and the mountain flowers are red and the purple trees are high and low. Then I realized that listening to the lock in the golden cage is not as good as the free singing in the forest; people are idle, the osmanthus falls, and the night is quiet in the spring sky. The moonrise scares the mountain birds, and they sing in the spring stream.
2. The strings of the golden river are opened in the middle of autumn, and the clouds fly away in mourning. The moonlight on the fairy palm passed by, and the lamp on the long gate dimmed and a few sounds came. It should be noted that Hu Qi is here one after another, how can he chase the spring breeze one by one? Don't be disgusted with Xiaoxiang, a place with few people, lots of water, wild rice and berry moss on the banks; swallows carrying mud in their mouths fly to the painting hall. He occupies a safe place in the apricot beam. He is so light that only his master can pity him. He is an enviable good karma.
3. How general is the boat? The water is empty and long. The clouds rise far away from Xiu, and the sunshine flows back. The noisy cicada forest is more than quiet, and the bird singing mountain is even more secluded. I miss this place so much, I have been wandering sadly and tiredly for many years; the spring is at the end of the world, and the sun is setting at the end of the world. The oriole's cry is like tears, and it is the highest flower in the wet; the petrel's age is small, and it will come temporarily in the spring. Little did he know that the mud was cheap, but the jade hall was open. When you are embroidering the house, you will go in twice, and you will go to the Huatang several times a day. Don't care about competing with things, don't guess at each other.
2. Birds
1. Birds are a class of the vertebrate subphylum and are the collective name for all bird animals. The body is streamlined, the skin is thin and tough; the body surface is covered with feathers, and the forelimbs usually become wings, and some species have vestigial wings; the chest muscles are well developed; the rectum is short; the heart has two atria and two ventricles, and the body temperature is constant.

Birds are found throughout the world. Most are active during the day, with a few birds active at dusk or at night. It can be divided into carnivorous, piscivorous, insectivorous and plant-eating types, as well as many intermediate and omnivorous types.
