Common species of the Sandpiper family, species classification of the Sandpiper

Common ones are the white-rumped curlew and the sandpiper.

The white-rumped curlew lives on the coast, in near-shore swamps, ponds, estuarine deltas, paddy fields, etc., and 20 to 30 individuals wade in flocks in the mud in search of food.

Sandpipers come in pairs or pairs to feed on a variety of insects along the banks of rivers or lakes. When walking continuously on the riverbank or lakeside, he keeps shaking his head and tail. When frightened, it is loud and noisy.

There are about 83 species of birds in 23 genera and 23 species of sandpiper (scientific name: scolopacidae). Medium or small waders.

The body color is dull and striped, and the mouth shape is varied, generally long and straight, and some are curved up or down, adapted to piercing through the mud and exploring food; Most species are similar in color to male and female, but there is a difference between winter and summer plumage. It is mostly found in the shallows of swamps, lakes, coastlines, rivers and other waters. They usually breed in the north and go south to spend the winter, and they marry during the migration season.

Good at long-distance migration, with the head and neck stretched forward in the flight posture, and the feet stretched back; Many species fly and chirp, and the sound is high-pitched. The food is mainly invertebrates such as crustaceans, worms, insects, shrimp, etc., but also feeds on fish, frogs and small reptiles. Most species of wading birds in this family breed in the northern hemisphere and overwinter in the warm regions of the southern hemisphere.

The sandpiper has a medium-length beak and legs, narrow wings, and a short tail; The body is about 35 centimeters long and weighs 300 grams. He is very timid, hiding in the mountains and forests during the day and rarely comes out to move, only flying out at dusk or dawn to look for food; It prefers coastal and inland marshy areas and mudflats of large rivers. usually alone or in groups of two or three; When eating, the mouth swings from side to side in the water to find food.

Able to fly slowly at speeds of up to 5 miles per hour without stalling, it is the slowest flying bird in the world. <

It is a small bird that lives by ponds and migrates every winter.

The destruction of homes, the lack of water in the wild, and the pollution of energy and waste to the environment have made many animals that once roamed freely in the forests and grasslands become rare species, and some can only be identified by **.

For example, the Siberian tiger, which once stomped its foot in the forest, shut down all animals, such as the extremely intelligent Vietnamese golden silk, etc., although humans have provided them with a place to simulate their innate environment, they have degraded to varying degrees in terms of skeletal form and hunting status, which undoubtedly brings difficulties to conservation work. Even more worrying are the fact that some species that cannot be kept and can only survive in the wild, after all, they are in high risk of becoming rare and becoming history, such as the spoon-billed sandpiper.

In 2020, more than 30 spoon-billed sandpipers were found in the mangrove reserve, and in 2021, a spoon-billed sandpiper was found in Zhejiang.

Judging from their appearance, they are still easy to distinguish from other birds, the most prominent feature is their large black mouth like a spatula and small size of no more than 16 cm, which makes them look cute, and their feathers will change color with the season, which can be regarded as a chameleon among birds.

The sky, tree holes, water surfaces, and beaches have basically become the habitat of various birds, and the noble birds are more special, they like to perch on the edge of swamps and ponds, and have extremely strict requirements for the surrounding water quality environment, which is simply a fight with the nobles of the plant - water leeks, of course, this is closely related to their eating habits, in the silt of swamps and ponds there are usually a lot of crustaceans and insects to survive, and they happen to be the staple food of noble birds, when eating, they will seep their spatula-like mouths directly into the mud and stir them back and forth in search of food.

As early as 2000, the noble bird was listed as critically endangered internationally, and the remaining survival population has been declining sharply every year, and this grim situation is really worrying scientists around the world. Unable to improve their living conditions in the wild and having difficulties in transporting adult birds, the UK simply brought the eggs back to their home country for incubation, which largely preserved the survival of the species.

This is an animal that is about to become endangered, and then it is a rare and protected animal of the state, and it also belongs to birds, and its mouth is generally black, and its whole body is black in summer, and its feathers are brownish-red.

It's a very rare species, and then the number of people that exist is also very rare, it's a critically endangered species, and it's very precious.

It is a creature that is about to become extinct, and this creature has a particularly large mouth, which should be orange, in fact, the overall shape looks very strange, mainly because the current environment seems to be not suitable for their growth operations, and it is about to be endangered.

A very rare species, this bird is very rare, outnumbered by the giant panda, and lives in that part of Russia, with a small body.

It is an endangered species and a very rare animal.

There is still controversy about the classification of sandpipers, according to the commonly used classification method, there are painted sandpipers, oystercatchers, sandpipers, anti-billed sandpipers, and webbed sandpipers. The markings and colors of the upper body are relatively bright in the sandpiper, hence the name of the sandpiper. The mouth is slender, the end is slightly curved downward and slightly inflated, the upper and lower beaks are sharp, and the end of the mouth is smooth without small dimples.

The nasal folds extend almost to the end of the mouth. The neck is short, the wings are wide (the secondary flight feathers are longer), and the flange is protruding outward. The tail is short, with 14 tail feathers.

The anterior and posterior margins of the tarsoplantar are covered with shield scales, and the hind toes are well-developed and high. The females are larger than the males, and the plumage color is more showy, and the young birds are similar in color to the males. The tail fat gland is feathered.

The cecum is well developed. There is a phenomenon of sexual reversal.

Lives alone, is active in the morning and dusk, eats insects, mollusks, worms, grains. The nest is hidden in the plant, the number of eggs in the nest is 2-5, and the skin is yellow. One female and many males, with males incubating eggs and brooding. Chicks are early adults.

There are two kinds of families, one of which is produced in China, namely the painted sandpiper (Rostratula benghalensis) distributed in the monsoon area south of Liaoning Province and winters south of the Yangtze River. The body plumage is dull and striped. The mouth is elongated, most of them straight, and some are warped or arched.

The end of the mouth is mostly covered with leather, blunt but not pointed. The neck is longer. The anterior and posterior margins of tarsoplantar are often covered with shield-like scales, with slightly webbed or webbed toe bases, and hind toes are missing in some species.

The plumage is similar to both sexes.

It inhabits the coast, swamps, rivers, etc., and flies along the coast in groups during migration. Eats a variety of small animals. The recess in the grass is selected as the nest (strictly speaking, there is no real nest), and the number of eggs in the nest is 2-4, yellow or olive, with black or brown spots.

There are 76 kinds of undergraduate and 45 kinds in China. Common examples include the greenshank (Triginga nebularia). The mouth is slender (longer than 50 mm) and curved straight or upwards and downwards.

The legs are medium-long to very long, the tarsal plantar is scaled anteriorly and anteriorly, the hind toes are vestigial or absent, the foretoes are slightly webbed at the base, but the anti-billed sandpiper has more developed webs. The body color has prominent large dark spots, which contrast with the gray and white parts, and there are no fine markings. They live in groups, some swim well, breed in groups, the nest is a shallow nest in the sand or mud, some are lined with pebbles or grass, and some are high platforms made of tree branches.

The number of eggs in the nest is 2-5 (usually 4). Migration of northern species.

There are 13 species in this family, and 3 species are produced in China, such as the black-winged stilt (himantopus himantopus). Small body. The beak is medium or long, thin and soft.

The wingtips are long and the tail is medium-long. The tarsal plantar is slightly flattened, covered with shield scales, and the anterior three toes are webbed. Breeding feathers have orange or red patches.

Mateism may be multiple males with smaller males.

Aquatic, swim briskly, flexible, often swim quickly in small circles, forage for small animals such as crustaceans and insects stirred up in the water, and also eat certain plants. Build a sturdy nest with grass in an open area near the water. The number of eggs in the nest is mostly 4, and the olive yellow color has dark brown or black patches and stripes.

Males incubate eggs and brood, with some females assisting in brooding. The down feathers are light brown with light gray and black stripes and spots. Non-breeding season flocks live at sea.

There are three species in this family, and two species in China, such as the red-necked webbed sandpiper. Some scholars have incorporated the undergraduate directly into the Sandpiper family.
