Big Mouth Pelican Story Truth

The pelican lives by the water, and fish is its main food. It has a long, big mouth, and a large elastic sac is connected under the mouth. This sac is its most distinctive feature and an important tool for it to make a living and raise its offspring.

The sac under its jaw is like a fishing net with excellent performance. When there are many small fish in the water, it opens its mouth and puts the sac into the water together and swims forward. After a while, the bag was filled with water and fish. The pelican closed its mouth and squeezed the water out of the sac, leaving the fish in the sac. This action was repeated several times until the sac was filled with fish. Sometimes, pelicans will form a horseshoe shape around a group of fish, and then put their mouths into the water together, making it easy to catch fish. The pelican's big mouth can hold about 15 kilograms of fish or 14 kilograms of water, which is like a big bucket.

When a pelican feeds its chicks, the mother bird first eats the fish and digests it before returning it to the sac, so that the chicks can enjoy their meal in this special big bowl.

What kind of bird is the big beak of the four pelicans?

>The pelican is a bird with a very special appearance, and its weird big mouth makes people feel very ridiculous. Its mouth holds more than its stomach. Its large mouth can hold a week's worth of food. This big mouth is actually formed by the expansion of the front end of the digestive tract. It is measured that it can hold 12 liters of water!

Pelicans are very large among living birds. Even the smallest brown pelican is 2 meters long with its wings slightly spread.

Pelicans often live in groups in the wild. In addition to swimming, they spend most of their time on the shore basking in the sun or patiently combing their feathers. Pelicans have sharp eyesight and are good at swimming and flying. Even when flying high in the sky, fish roaming in the water cannot escape their eyes. If a group of pelicans finds a school of fish, they will line up in a straight line or semicircle to outflank the school, driving the fish to the shallow water on the river bank. At this time, they open their big mouths and swim forward, even the fish take the water with them. Once it has become its prey, it closes its mouth, contracts its mouth, squeezes out the water, and swallows the delicious fish into its belly for a delicious meal.

Pelicans like to bathe in the lake very much. After bathing, they start to preen their feathers, often using their mouths to preen for more than an hour. There is a yellow oil gland at the root of its short tail feathers, which can secrete a large amount of oil. In their spare time, they often use their mouths to smear this special "cosmetic" on the feathers all over their bodies, making the feathers smooth and soft, making them water-tight when swimming. Dip.

Brown pelicans fish differently than spotted-billed pelicans. They tend to live alone or in small groups and can dive into the water like loons. The neck is bent at first; when they approach the target, the neck quickly straightens and the sharp beak stabs the fish body. Brown pelicans have another way of fishing. They fly high into the sky, then slightly retract their wings, stretch their bodies, and suddenly plunge straight down from the air, splashing onto the water. Their huge bodies slap on the water surface, producing strong vibrations. It is said that this vibration sound can spread 0.8 kilometers away and can stun fish 1.5 meters underwater. When the stunned fish surface, they can hunt. This fishing method of brown pelicans has aroused great interest among scientists. How can their bodies withstand such frequent and powerful beating forces? After careful study, scientists found that the brown pelican's air sac system is very developed.

Under the skin of their chests, air sacs fill the space between the muscles and skin. After these air bags are inflated, it seems to add a layer of air cushion between the skin and muscles, which can greatly reduce the shock to the body when they "splash". Brown pelicans also have a less laborious method of catching food - waiting for fish that are panicked by sharks at the beach.

Nearly all pelicans have short legs, making them as clumsy as ducks when walking on land. In the water, pelicans can swim freely. When they swim, they close their wings and put them on their backs. They slowly paddle through the water with their webbed feet, and their bodies move forward steadily in the water like a small boat. However, it takes a little effort for the pelican to take off. On land, they have to take several steps before taking off; in water, they ride on the waves and reach a certain speed before taking off, just like an airplane needs to roll to accelerate before taking off. Once taken off, the pelican is free to fly.

During the breeding season, male pelicans often choose a tree as a nest site, then land on the tree to pay attention to passing females. If the female bird likes it, she will land next to the male bird. After that, the male bird finds branches, water plants and other nest materials for nest building. The male and female birds build the nest together, followed by mating, egg laying and egg incubation. The tasks of incubating and raising young pelicans are shared by both parents. Some pelicans congregate at breeding sites far from their feeding grounds. In order to ensure that their offspring and themselves have enough food, they must fly 50 to 60 kilometers every day to fish. Instead of using their large mouths to bring food to their chicks, these pelicans swallow the fish whole. When it returns to the nest, it opens its mouth and lets the chicks put their mouths into its esophagus to cause vomiting. The chicks feed on the semi-digested chyme spit out by their parents. The length of a pelican's big mouth is equivalent to five times the length of the chick's body. Some chicks simply stand in the parent bird's big mouth to eat. Pelicans often gather together to breed, and sometimes help feed each other's chicks. Sometimes several pelicans even argue over feeding a particular chick.

Pelicans can cope with bad weather, but they cannot cope with man-made disasters. In the 1960s, due to the overuse of the pesticide DDT in agricultural production, pelicans' eggshells became thinner, making it impossible for them to hatch young, and pelicans in some places became extinct. The brown pelican is the state bird of Louisiana, but the pelicans there have been wiped out by pesticides.
