       It’s a sparrow or a magpie

       Why birds can fly:

       1. The heart of birds is completely divided into two ears and two ventricles, which not only enables the whole body to obtain oxygen rich fresh blood, but also keeps their body temperature constant, which is conducive to flight.

       2. Birds do not have bladder, rectum is also very short, do not store feces and urine in the body, the urine and feces are discharged from the body at any time. This is also the result of losing weight and being suitable for flying.

       3. The structure of its skeleton, digestion, excretion, reproduction and other organs is conducive to weight loss and flight enhancement. Therefore, birds can overcome the gravity and fly high.

       About sparrows:

       1. The life span of sparrows is relatively short, and the survival rate is not high. Only one of the eight young birds that can fly can survive to be passed on. The oldest sparrow on record lived only eleven years.

       2. Sparrows must have nests to survive the winter. Without shelter and food, sparrows can only live for 15 hours at zero temperature.

       About magpies:

       1. Magpie is omnivorous. It forages in the wild and fields. It preys on locusts, mole crickets, ground tigers, scarab beetles, moth larvae and frogs and other small animals. It also steals eggs and chicks of other birds, and also eats fruits, grains and plant seeds.

       2. Magpies were the most common birds before the 1980s, and some places have been extinct since 1980s.

       3. Magpies are very sensitive to the environment. Environmental pollution and forest degradation have seriously affected the habitat of magpies. The disappearance of magpies indicates that the ecology of this area has been out of balance.

       History of birds:

       1. The first birds appeared about 220 million years ago.

       2. Their bodies are spindle shaped, their forelimbs are specialized into wings, their body surface is feathered, their body temperature is constant, their muscle chest is developed, their bones are healed, thin and hollow, and their brains are relatively developed.

       3. Air bags can be used for double breathing. Without bladder and rectum, feces can not be stored, which can reduce body weight.

       Examples: swallows, Thrushes, woodpeckers, owls, magpies.

The birds on the earth can be divided into six categories: the swimming bird, the wading bird, the climbing bird, the walking bird, the Raptor and the songbird.

There are many spaces in the bone, which are filled with gas. In addition to the lung, the respirator has an air bag to assist breathing. Its main characteristics are that the whole body is covered with feathers, the forelimbs become wings and can fly in the air; the body temperature is constant and high, up to 40 ¡æ. Adapt to flying, the bones become lighter.

       Birds change their habitats in different seasons, or move from the nesting site to the wintering site, or return from the wintering site to the nesting site. This seasonal phenomenon is called migration. Because of the different migration habits, birds can be divided into resident birds, summer migrants, winter migrants, travelers, fans and so on. Bird migration usually takes place in spring and autumn. The migration in autumn is to leave the nesting area, the speed is slow; in spring, the migration speed is faster because of the rush to breed.
