My Deep-sea Fishery

Xiang Yang carefully looked at the red-crowned cranes above his head, and at the same time distinguished their calls.

The tone and frequency of the red-crowned crane's sound vary greatly depending on gender, age, behavior, and environmental conditions.

Generally, the red-crowned cranes chir in a string or single, and they not only chirp when taking off and flying in the air, but also when they are feeding and resting on the ground.

It can be heard almost every day throughout the year, but it is most frequently heard around dawn.

Every day before the break of dawn, as long as there is one ringing first, there will be a second responding immediately, and then the group will respond to each other in a series, and the joy will not stop until sunrise.

The call of the red-crowned crane is not only used to communicate and communicate between spouses and group members, but also often used to express commotion and alert to danger, but more importantly, it is used as an accompaniment to marital dance.

When the male bird in the breeding period sings against the female bird, his head is upright and his wings vibrate frequently, making a high and long single tone in one beat. There are two or three short, sharp polyphony in the beat.

This duet is not only a red-crowned crane's confession of love, but also a warning to attempted invaders, and it can also promote the synchronization of male and female sexual behaviors and ensure the success of reproduction.

The chirping of chicks mainly asks for food.

The one-year-old baby bird guards the territory and calls aimlessly after leaving its parents.

Red-crowned cranes after the age of two have humming and crowing before mating.

In addition, there are calls when calling for take-off and alarm, and calls when camping and so on.

"Fang Youqun." Xiang Yang shouted suddenly.

"What's wrong? Brother Yang." Fang Youqun asked immediately.

Xiang Yang smiled and asked, "Have you seen Crane Dance?"

"Crane Dance?" Fang Youqun wondered.

"If you haven't seen it, watch it carefully. After a while, these red-crowned cranes should be able to dance." Xiang Yang said with a smile.

Whenever the red-crowned cranes arrive at the breeding grounds, they begin to pair and occupy the nest area. The male and female birds announce their possession of the area by constantly calling each other in the nest area.

When courtship is also accompanied by singing, and often the male bird's beak is pointed upwards, his head and neck are raised up, his wings stand up to the sky, and he sings loudly and makes a loud voice of "he, he, he".

The female birds responded loudly, then crowed, jumped and danced to each other.

Red-crowned cranes dance very gracefully, either stretching their necks and raising their heads, or bending their knees and waist, or stepping on the spot, or jumping in the air, sometimes picking up pebbles or twigs and throwing them into the air.

Most of the red-crowned crane dances consist of dozens or hundreds of continuous changes.

The main movements of dance include stretching the waist and raising the head, bending the waist, jumping, jumping and kicking, walking with wings spread, bending the back, bowing, holding objects, etc., but the posture, amplitude, and speed are different.

And these actions and their subsequent actions are organically combined, such as bending down-stretching the waist and raising the head-head swinging up and down rapidly.

Spread your wings-stretch your waist and raise your head-bend down.

Stretching and raising your head-bending over-jumping with your feet down.

Spread the wings and bend over—walk at the waist—the neck and body are in a figure eight shape with the wings spread—and walk with the wings spread.

Holder—jumping parabola—rotates the body without changing its position.

Red-crowned cranes can jump, bend over, etc. by relying on their leg strength or fanning their wings.

Most of these actions of red-crowned cranes have a clear purpose. For example, bowing generally expresses friendship and love.

The whole body is tight and bowed in salute, which means to express his own existence, show off, and intimidate.

Bending over and spreading wings means being contented, leisurely and entertaining; spreading wings sometimes means cheerful mood, etc.

"Look carefully, the chances of encountering red-crowned cranes in the wild are rare." Xiang Yang said with a smile.

The population status of red-crowned cranes is very miserable.

Red-crowned cranes need a clean and open wetland environment as their habitat, and they are the indicator organisms most sensitive to changes in the wetland environment.

Due to the increasing number of humans, the habitat of red-crowned cranes has been continuously transformed into farmland or cities. For example, the moon bubble in western Jilin used to be the breeding ground of red-crowned cranes. Because of the artificial enclosing of lakes and embankments, the water level in the embankments has risen, and the emergent vegetation belt is basically Disappeared, the floodplain of the lake outside the embankment dried up, reclaimed into farmland, and the red-crowned cranes also disappeared.

Another example is the marshland between Shaobo Lake and Gaoyou Lake in our country, which was once a wintering ground for red-crowned cranes. As the number of people who fish, herd, and hunt in the area continues to increase every year, human interference, egg picking, poaching, etc. have increased. The number of red-crowned cranes has dropped sharply.

The total number of red-crowned cranes in the world is estimated to be only about 2,000, of which about 1,000 live in the winter in our country. The protection of red-crowned cranes and their living environment has attracted more and more people's attention.

my country has established more than 20 nature reserves focusing on the protection of red-crowned cranes. Among them, Xianghai, East Dongting Lake, and Poyang Lake have also been included in the international list of wetlands protected by the Ramsar Treaty. Great progress has been made in the protection work.

The red-crowned cranes on the sea are very difficult to see in other waters except for the hundreds of fishes in Hokkaido’s fishing grounds that have stayed forage for a long time.

This time, Xiang Yang sailed to the vicinity of Naha, and the group of red-crowned cranes was probably the group of red-crowned cranes that had stayed in the fishing grounds of Hokkaido for a long time.

In the history of our country, the red-crowned crane is recognized as the first-class literary bird.

The Ming and Qing dynasties gave red-crowned cranes cultural connotations of loyalty, integrity, and high moral character.

The service of civil officials, the red-crowned crane embroidered by the first-class civil officials, listed it as an important symbol second only to the royal dragon and phoenix, so people also called the crane the first-class bird.

People also regard the crane as a symbol of high-ranking officials.

In fact, the legendary crane is also a red-crowned crane. It is a large wading bird that lives in swamps or shallow waters. It is often called the "God of Wetland".

It has nothing to do with the pine trees that grow in the mountains and hills.

However, because the red-crowned crane has a life span of fifty to sixty years, people often paint it with a pine tree as a symbol of longevity.

Residents of East Asia use red-crowned cranes to symbolize happiness, auspiciousness, longevity and loyalty.

It appears frequently in literature and art works of various countries. In the tombs of the Yin and Shang dynasties, the image of cranes appears in sculptures.

Bronze clocks in the Spring and Autumn Period and Warring States Period, and ritual vessels in the shape of cranes have appeared.

Xiang Yang was still admiring the group of red-crowned cranes. At this time, Chen Qingsheng’s voice came again from Xiang Yang’s walkie-talkie. Chen Qingsheng’s voice was very helpless, "Boss, the fish in the fishing nets are too tight, I am afraid there is no way at all. Put another rope into the fishing net. What should I do now? Is it just abandon the net?"
