What season is the wheat bird called? How to choose a wheat bird

This bird, whatever the season, is when the wheat comes out.

That is, from the time the wheat comes out until the wheat is harvested, probably in the summer.

Birds. Birds are usually feathered, oviparous animals with a very high metabolic rate, and the long bones are mostly hollow, so most birds can fly. Birds are made up of reptiles.

Evolutionary has led to more than 9,000 species of birds living in the world, all of which have wings and feathers, including those that have lost their ability to fly (such as ostriches, penguins, etc.). The first birds appeared 100 million years ago.

The body is spindle-shaped, the forelimbs are specialized into wings, the body surface has feathers, the body temperature is constant, the musculothoracic is developed, the bones are healed, thin, hollow, and the brain is relatively developed. Having an air bag allows for double breathing, and not having a bladder can reduce body mass. These physical traits are well adapted to flying.

Birds have no teeth but have beaks that can be used to hunt, build nests, and groom their feathers. Birds are good at building nests, and they can build all kinds of nests from the materials they collect. Ornithischia in taxonomy.

Upper is a subphylum of vertebrates.

under one of the classes. Feather.

Birds are the only animals on earth that have feathers. The vast majority of a bird's body surface is covered with feathers, which not only keep the bird at a constant body temperature, but also allow it to fly. Birds have different shapes of feathers.

Structure. The ** of a feather has a hard shaft, called the feather shaft, the upper feather part is called the feather trunk, and the lower part inserted into the ** is called the feather root. The feather trunk is flanked by feathers, which are made up of a tough substance called keratin, which in turn is made up of feathers and branchlets.

Grow. Feathers are made up of follicular vesicles on the feathers of birds**.

out, the parts are put together in a special way. Most birds moult at least once a year, when new feathers grow and old feathers fall off. Birds renew their already damaged feathers through moulting.

Freshman. Birds usually moult twice a year, which shows that feathers have a strong ability to regenerate. Scientific studies have shown that feather stem cells are distributed in a ring on the wall of the feather follicular vesicle, which can proliferate and differentiate, and the differentiated cells grow upwards to produce feathers.

The proliferation and differentiation of feather stem cells allows the entire feather organ of birds to grow and regenerate.

Type. Bird feathers can be broadly divided into four types: body feathers, down feathers, tail feathers, and wing feathers.

The body feathers cover the whole body, forming a smooth, streamlined body surface of birds; The down is fluffy, so that the warm air will not dissipate quickly; The tail feathers and wing feathers are more powerful and are used for flight.

Because the cuckoo is a migratory bird, it comes from the warm south in spring to live, and when it comes home, it is afraid of getting separated, so it is necessary to chirp vigorously.

More color, posture to choose.

Build a bird's nest. 1. Build a nest of wheat slippers at a distance of meters from the ground, the bottom can be supported by cement columns or large trees, and a honeycomb multi-layer nest of wheat nests can be built on top, which can be as high as dozens of meters to the space, generally covering an area of 30 square meters.

2. Each ecological park can build 2-4 breeding houses for wheat stalks, and each breeding house can breed more than 100,000 birds every year.

3. Generally, the thickness of the wall is 35-50cm, and both sides of the wall are built into a nest of wheat slippers, with a distance of 15cm between the nest and the nest, and the partition wall is 5-8cm, the exit of each nest is 4cm in diameter, and the space of the nest is 8-10cm, which is about as big as a human fist.

4. The main materials are red brick cement, adobe, perlite and cement, foam board (benzene board), soil and weeds, beverage bottles, large-mouth glass bottles and so on.

Cultivation methods. Using ecological, free-range, natural breeding methods, the wheat bird likes to fly all over the sky, there is no big cost in the breeding process, no need to feed other food, generally eat natural grass seeds and insects.

Survival characteristics. 1. The place where the wheat bird lives, usually under the eaves where humans live, likes to go out early and return late, and works hard to reproduce offspring.

2. The wheat slicker bird is muscular, has very strong flexible flight skills, and the ability to catch insects is also very strong, and it can be caught by all kinds of fixed and flying insects.

3. The wheat slipper bird can not only fly vertically up and down, but also fly in a sharp turn of 90 degrees, and the muscles have relatively strong hardness, and the meat is dark red.
