Why do birds have different beak shapes?

In September 1835, Darwin landed on the Galapagos Islands, near the equator in the eastern Pacific Ocean, and found that the islands were inhabited by small birds not seen anywhere else, and that were similar except for a slight difference in the size and shape of their beaks. Darwin collected some specimens and brought them back to London. According to experts, there are a total of 12 different species of these birds.

Later, they, along with three other species, made a total of 15 species of small birds that lived in the Galapagos Islands, and were collectively known as "Darwin's finch". It has been found that the differences in the beak shape of these Darwin's finches typically show the specific evolution process of the species, and thus become living evidence of Darwin's theory of species evolution.

If you love birds, you'll also find birds with a variety of beaks. For example, the beak of a chicken is short and delicate, the beak of a duck is flat and flat, the beak of an eagle is curved and hooked, the beak of a woodpecker is like a sharp cone, the beak of an egret is like a spear, the beak of a hummingbird resembles a thin tube, the beak of a flamingo is bent, the beak of an anti-billed sandpiper is upturned, the beak of a toucan is larger than its head, and the large beak of a hornbill has a helmet ...... on top of itWhy do birds have so many forms of beaks?

In the long history of evolution, as the forelimbs of birds evolved into wings that took on the function of flying, the beaks of birds had to do more things, so they also had more functions, such as feeding, fighting, nesting, feather management, etc. In particular, the diverse feeding behaviors of birds are the main reason for the alienation of birds' beak shape. As a result of living in different environments, the feeding habits of birds have also diverged.

As a feeding tool, the bird's beak has undergone adaptive changes. For example, the short, powerful beak of a chicken is convenient for pecking at seeds on the ground; The duck's flat beak is suitable for filtering aquatic plants in water; The eagle's hooked beak is good for tearing apart its prey; The woodpecker's cone-like beak gouges through the bark of trees to find bugs hiding inside; The egret's spear-like beak can poke fish; Hummingbirds suck nectar ...... with their tube-like beaksThe bizarre beaks of flamingos, sandpipers, toucans and hornbills are also the result of their adaptation to their habitats and feeding behaviors. <>

According to the feeding habits of birds, we can divide birds into four groups, namely carnivorous birds, insectivorous birds, cerealivorous birds, and omnivorous birds. Of course, it can also be roughly divided into hard-eating and soft-eating birds. Birds with different feeding habits have different shapes of beaks and different feeding patterns.

The following is an introduction to the main characteristics of the beak shape and feeding mode of the four groups of birds, which is very helpful for raising good birds.

Some birds have chiseled beaks, like woodpeckers; Chickadees, willow warblers, etc., which feed on insects among tree trunks and branches and leaves, have slender and pointed beaks; Wrens, on the other hand, mainly hunt insects in the air, so their mouths are mostly flat and broad, and their mouth whiskers are also more developed.

There are the most species of insectivorous birds, and most of them are beneficial birds for agriculture and forestry. However, this kind of bird has relatively high requirements for breeding technology and is prone to death. <>

The main reason for the variety of beak shapes in birds is that the different feeding patterns of birds are different due to the different environments in which they live. As a feeding tool, the bird's beak adapts to the changing environment of its life.

Why are the beaks of birds diverse

As a result of living in different environments, the birds' beaks have also undergone adaptive changes as a feeding tool. For example, the flat beak of a duck is suitable for filtering aquatic plants in water, and the hooked beak of an eagle is good for tearing apart prey, etc.

The beak of a bird is called a beak, and the extant bird has no teeth, and the beak functions as a tooth and a lip. Because the forelimbs of birds evolved into wings, and because they have various functions to replace the forelimbs of other animals, the beak is well developed, and it acquires various forms according to different living habits.

In particular, the adaptation to predatory habits is more obvious, and the beaks of insects and nectar suckers are mostly slender, while the beaks of cereal food are mostly conical. Occasionally, there will be cephalopods.

The mouthparts are called beaks. All ceratosaur dinosaurs had beaks, which were used to cut plants, but also had teeth for chewing.

The role of the beak. The most important function of the beak is, of course, to eat, but in addition, since birds do not have hands, the beak also takes on most of the functions of the hand: it can be used to pick up things when you want to transport things, it can be used to fight when you are in danger, it can be used to comb when the feathers are messed up, and so on.

Birds have their own dietary preferences, some are carnivorous and some are vegetarian.

Some are all-you-can-eat. What they like to eat is closely related to the shape of their beaks.

Meat-eating birds have sharp hook-like beaks, which are ideal for tearing up prey. Fish-eating birds have flattened beaks, and some have tooth combs on both sides of their beaks that help them prevent the fish from escaping when they catch them.

Bug-eating birds have long, pointed, slender beaks that help them catch bugs from branches and crevices in the ground. Most of the seed-eating birds have conical beaks, which act like vices.

You can bite the hard shell of the seed and eat the seed inside.

Bamboo chicken. Tender and delicious, also known as tenderness and deliciousness"Slippery"、"Bamboo partridge"or "flat tank jar".

It belongs to the order Chickenformes, Pheasantidae.

The bird's plumage is brightly colored.

It is an ornamental bird endemic to China and a common species in the south.

Male birds are aggressive by nature and are often domesticated as fighting birds for viewing.

This bird was introduced to Japan in 1919 and is very popular.

Wild bamboo chickens are distributed in the mountainous areas of the provinces south of the Yangtze River.

Among the birds, there is a short-billed pepper bird, the beak peak is 10-12 mm long, and its body length is 17-20 cm.
