What birds are there in spring?

In spring, there are birds such as swallows, woodpeckers, cuckoos, orioles and magpies.

swallow

Domestic swallow (scientific name: Hirundo rustica): It is a bird of the genus Swallow. The beak is short, wide and flat, with a wide base and an inverted triangle, and there is a notch near the apex of the upper beak; The mouth is deeply cracked, and it must be underdeveloped. The wings are long, narrow and pointed, and the tail is forked, forming a "dovetail". The feet are short and thin, and the toes are three in front and one behind. The main features are blue-black upper body, metallic luster and white abdomen. Light and agile, with long and narrow wings, it flies like a sickle and its tail splits like scissors. Flying as fast as an arrow, up and down, east and west, can quickly change direction.

They are often seen in pairs in the fields near the village and on the branches of the river bank, on telephone poles and wires, and often fly over the fields and beaches in groups. When flying, they open their mouths to prey on flies, mosquitoes and other insects. This song is sharp and short. Worldwide, it is the national bird of Estonia and Austria.

2. Woodpecker

Woodpeckers are well-known forest birds. In addition to killing pests under the bark, such as longicorn larvae, the traces of chisel wood can also be used as an indicator of healthy logging in forests. It is a common resident bird, and there are green woodpecker and spotted woodpecker widely distributed in China. They feed on some pests, such as longicorn beetles, brown beetles, winged moths, smelly bedbugs, etc., and can eat about 1500 every day. Because woodpeckers eat a lot and have a wide range of activities, in the forest of 13.3 hectares, if a pair of woodpeckers inhabit, more than 90% of insects can be pecked away in a winter.

cuckoo

Rhododendron: It is a China subspecies of Rhododendron. The body length is about 320 mm, the wing length is about 2 10 mm, and the male bird's upper body is pure dark gray; The wings are dark brown, white and mixed with brown spots; The tail is black and the top is white; The central tail feather has white fine spots along both sides of the feather axis; The chin, throat, upper chest, head and neck are light gray, and the rest of the lower body is white with dark brown horizontal spots. The male and female birds are similar in appearance, but the upper body of the female bird is gray and brown, and the chest is brown. Also known as Ga Gu, oracle bone, Zi Gui, Du Yu, Guo Gong and Huo Gu.

Habitat in open woodlands, especially by the water. Often sing in the morning, 24-26 times per minute, stop singing for half an hour. Sexual cowardice is often hidden in leaves. Usually I only hear singing, but I seldom see it. Flying fast, walking in a straight line, often have to slide a distance before landing. Feeding on Lepidoptera larvae, beetles, spiders, snails, etc. Eating in large quantities has a considerable effect on eliminating pests.

Distributed in western and southern China, India, Nepal, Myanmar and Thailand.

4. Orioles

An oriole is a medium-sized sparrow. The appearance and size are similar to that of orioles, with a body length of 23-27 cm. The whole body is golden yellow, and the wings and tail are black. The headrest has a wide black stripe, which extends to both sides and connects with the pattern of dark circles, forming a black belt around the top of the head, which is very eye-catching in the golden head. The occipital bone of similar orioles is not black, and the black eye lines do not extend to the occipital bone. Their distribution areas are also different, so they will not be confused in the wild. Male and female feathers are similar in color, but female feathers are darker. Young birds have longitudinal stripes. Gorgeous body color.

Insects are staple food, and they also eat fruits and seeds. Arboreal birds rarely move on the ground, like to flock, and often shuttle between trees in pairs. Crying is sweet.

5. Magpie

Magpie (scientific name: Pica pica) is a bird of finch family. * * * There are 10 subspecies. The body length is 40 ~ 50 cm, and the male and female feathers are similar in color. The head, neck, back and tail are all black, showing purple, green, blue and green luster from beginning to end. The wings are black and there is a big white spot on the shoulder. The tail is much longer than the wings and is wedge-shaped. The mouth, legs and feet are pure black. The abdomen is bounded by the chest, and the front is black and the back is white. Stay birds.

Habitat is diverse, often found in human activity areas, like to nest in trees next to houses. Most of them live in pairs all the year round, omnivorous, foraging in the wilderness and fields, preying on insects, frogs and other small animals during the breeding season, stealing eggs and chicks from other birds, eating fruits, grains, plant seeds and so on. Each nest lays 5 ~ 8 eggs. Eggs are light brown, cloth brown and grayish brown spots. Female birds hatch eggs, the incubation period is about 18 days, and they leave the nest about 1 month.

Except South America, Oceania and Antarctica, it is almost all over the world. There are 4 subspecies in China, which are found all over the country except grassland and desert areas. Magpie is a symbol of good luck in China, and it has been a custom to draw magpies to express happiness since ancient times.

Extended data:

There are more than 9020 species of birds in the world, and there are more than 400 species of/kloc-0 in China. According to the morphological and structural characteristics of birds, they can be divided into two subcategories: ancient insectivores and modern insectivores. The species of archaeopteryx has long been extinct, and only fossil specimens, called Archaeopteryx lithographica, are intermediate types that evolved from ancient reptiles to birds.

Neornithes, also known as Neornithera, can be divided into three orders: Dentata, Flat-breasted, Penguin and Convex-breasted. Except for toothlike birds, reptiles are more perfect than amphibians in morphological structure and physiological characteristics, so they once flourished in Mesozoic, not only with a wide variety, but also with different shapes and lifestyles, occupying land. The existing species are just some remnants of that year.
