What are the characteristics of swallows

Swallows are a bird that belongs to the passerine order, and here are some of the characteristics about swallows:

Physical characteristics: Swallows usually have a small, slender stature, a thick beak, and strong wings. Their colors are usually dominated by black, white, and blue, and they have a beautiful, elegant appearance.

Flying Ability: Swallows are known for their excellent flying performance, displaying sailing skills and swift speed and frequency in the air. Swallows can quickly change direction while flying, swoop down to catch insects, and then quickly rise into the air again.

Breeding habits: Swallows usually breed during the summer months, choosing buildings, bridges, caves, etc. as nests. They can lay up to four to six eggs per year, and each nest may hold several young swallows.

Long-distance migration: Swallows have a habit of migrating long distances, about twice a year. Swallows travel north in the spring, where they breed and forage in warmer climates; Head south in the fall, return to temperate regions and avoid cold climates.

Ecological role: Swallows mainly live by flying to prey on insects, so they play an important role in controlling the number of pests in nature. At the same time, swallows are also food for some other carnivores**.

In conclusion, the swallow is a beautiful, flexible and efficient bird with excellent flight ability and excellent breeding habits. At the same time, swallows also play an important role in the natural ecosystem.

Swallow. Description of the characteristics.

The 50-character one is: Swallow is a genus of the passerine swallow family. This genus of birds is small, with a body length of 130 to 180 mm. The wings are long at the tip and the tail is forked. Most of the back feathers are blue-black, so it was called Xuanniao in ancient times.

The wingtips are long and good at flying, the beak is short and weak, and the beak is wide and lobed, which is the beak shape of a typical insectivorous bird.

The feet are short and the claws are strong. There are 20 species in the world and 4 species in China, among which house swallow and golden-rumped swallow are more common. The house swallow has a chestnut red front waist, an irregular horizontal band on the back chest, and a milky white abdomen.

Swallows generally breed from April to July. House swallows nest under the eaves of a farmhouse. The nest is made by gluing mud and grass stalks with saliva, and is covered with fine weeds, feathers, rags, etc., and some Artemisia annua leaves.

The nest is dish-shaped, and it breeds 2 litters per year, mostly from May to early June and mid-June to July, and each nest lays 4 to 6 eggs. The second litter is fewer, 2 to 5 eggs, milky white, male and female incubate.

Swallows are mostly found in the air near settlements, on telephone poles, or on buildings. It flies back and forth when foraging and nesting. When looking for food, they will open their mouths while flying to welcome flying insects into their mouths.

It mainly feeds on small insects, such as mosquitoes, flies, etc., and belongs to beneficial birds. When the temperature drops down in autumn, they fly south in droves, and then fly back to the place where they lived when the flowers bloom in the spring of the following year.

The characteristics and characteristics of the swallow are as follows:

1. Characteristics of swallows.

The swallow has a body length of 130 180 mm, a long body, a small and pointed mouth, a large jaw, thin wings and a forked tail, and a long wing tip, and most of the back feathers are blue-black. The wingtips are long and good at flying, the beak is short and weak, and the beak is wide, which is the beak shape of a typical insectivorous bird, with short feet and strong claws.

2. Characteristics of swallows.

Swallows are small in size and have scissor-shaped tails, which are conducive to quickly changing the direction of flight; In addition, during flight, swallows often encounter airflow obstruction, and the streamlined shape of the tail can minimize the resistance; Its tail can also balance its body, adjust its speed, and control its rise and fall during flight.

The habits of the swallow

In winter, the swallow eats a large amount of food** in temperate regions, so many species migrate, but unlike most other passerine migratory birds, the swallow migrates during the day and flies at low altitudes.

In addition, they often forage on their migratory routes, so their fat reserves are lower than those of other migratory birds of the same size, and the species that breed in Africa often migrate with rainfall patterns, but the exact situation is little known, migrating to the north in early spring each year, spreading throughout the country in summer, and then migrating south in flocks to wintering in India, the South Ocean Islands and Australia.

The habits of swallows are as follows:

Food: The swallow's diet is mainly aerial insects. There are a small number of species of swallows that will eat some plants, but they eat well. When the swallow catches the bug, it will not wait for the bug to come to the door, but will take the initiative to attack.

Breeding: Swallows breed from April to July. They build their nests under the eaves, and their nests are made of dirt, grass and spit, so they are relatively strong.

Swallows breed two litters of baby swallows each year, each nest laying 4 to 6 eggs from the former nest, and the second nest gets a little less than the first.

Migration: Many species of swallows migrate because food is scarce in temperate regions during the winter season, so they migrate to the south to hotter places in order to survive. Swallows generally migrate during the day, and they fly very low when they migrate to make it easier to forage for food on their way.

Swallow introduced

The swallow is a beneficial bird with a small body with long pointed wings and forked tail feathers, which prey on insects while flying. According to statistics, there are as many as 75 species of swallows in the world, including Lou swallow, white-rumped swift, house swallow, rock swallow, gray sand swallow, golden-waisted swallow and hairy-legged swallow, etc., and there are 4 genera and 7 species of swallows in China. The call of the swallow is a simple and rapid chirping or buzzing sound, and the usual chirping is longer and the syllabic order is varied.

Swallows generally live an average lifespan of 11 years, with a minimum of 7 years, but only if there are no accidents during the migration. Before winter, the swallows make their annual long journey, flying in flocks from the north to the far south, where they enjoy the warm sunshine and humid weather, leaving the frost and bitter winds of winter to the chickadees, grouses, and ptarmigans, which never fly south for the winter.

The first paragraph of "Swallow" describes the characteristics of liveliness and wit.

This feature is made up of jet-black shiny feathers, handsome and light wings, and a scissor-like tail.
