What are the birds?

Birds in my country include swimming birds, wading birds, climbing birds, land birds, birds of prey, and songbirds. The scientific classification includes: Anseriformes, Apodemus, Nighthawks, Charadriiformes, Ciconiiformes, Columbiformes, Sangivaliformes, Cuculiformes, Galliformes, Loons, Gruiformes, Accipitridae, Gulliformes, Passeriformes, Pelecaniformes, Pipitiformes, Strigiformes, Trogons, and Falconiformes.

Birds generally refer to the class Aves, which is a class of the subphylum Vertebrata. Birds are all covered with feathers, are warm-blooded, lay eggs, and have an amnion outside the embryo.

Birds have wings or degenerate forelimbs, and most of them fly. Their hearts have two atria and two ventricles, and only the right aortic arch is preserved. Birds have many hollow spaces filled with gas, and their respiratory organs include lungs and air sacs to assist breathing.

Why does the bird keep opening its mouth?

There could be many reasons why a bird keeps its mouth open.

1. The bird keeps its mouth open, which may be caused by a serious cold.

2. If a bird always opens its mouth, it may be suffering from asthma or being frightened.

3. The bird always opens its mouth, maybe it is hungry and wants to eat.

Lifespan of birds: Generally, small birds live less than ten years, larks can live for 40 years, eagles can live up to 80 years, and large parrots can live 80-100 years.

For newly caught wild birds, fear of people, banging against the cage, refusing to eat, and being nervous and alert are all normal stress responses. As the bird becomes more mature, the symptoms will improve.

The bird may be sick if it keeps opening its mouth. Parasites are living in the bird's respiratory tract, making it unable to breathe normally and it can only open its mouth.

The most beautiful bird in the world

There are many beautiful birds in the world. Different people have different aesthetic standards, and we cannot subjectively say which bird is the most beautiful. The beautiful birds include: peacock, bird of paradise, flamingo, red-crowned crane, egret, bowerbird, oriole, black-necked blue flycatcher, golden pheasant, swan, etc.

The peacock is generally more than 2 meters long, of which the tail screen is about 1.5 meters. The tail screen is mainly composed of the coverts above the tail. The coverts are very long, with brightly colored and shiny tips. The male peacock will spread its tail screen during the courtship period to attract the attention of the female peacock.

The bird of paradise is generally 15-110 cm long and weighs 50-450 grams. Most male birds of paradise are colorful and have complex and gorgeous feather ornaments.

Flamingo, also known as red flamingo, has white body feathers with rose color, black flight feathers, and dark red coverts. The various colors complement each other and are very beautiful.
