Beginning in late September, migratory birds travel from the far north, even along the coastline of Siberia, to be hungry and exhausted after days of travel, in desperate need of energy.

They have finally arrived in the warmer south and need to find a suitable habitat to spend the winter.

In previous years, large groups of migratory birds usually traveled to wetland nature reserves dozens of kilometers away, but this year, a group of migratory birds discovered large areas of water on the way to fly.

From the vast man-made lake, to the swan lake where a large number of swans gather, to the metasequoia forest, some birds are attracted by the good ecology and abundant food here, and finally choose to land on the island in the center of the lake.

The island in the middle of the lake is surrounded by lake water on all sides, forming a closed environment where no one disturbs it.

The island is densely vegetated, with tall trees such as metasequoia, pond cedar, larch and conifers, and various bushes, ferns and mosses filling the island.

Large areas of reeds are scattered around, which is very concealed, and is a favorite place for migratory birds; The water of the lake is clean and clear, and the environment is natural.

The most important thing is that the aquatic plants are dense, the fish and shrimp are plump, and there is a very sufficient food for them to overwinter.

Just as plants need to accumulate a lot of nutrients to bloom, these migratory birds need to be well replenished during the cold winter months so that they can fly back to their breeding grounds and give birth to healthy babies the following year.

For that matter, this aquatic forest has a fatal attraction for them.

It is also the reason why so many birds gather on the island in the middle of the lake.

According to Director Cao's rough observations, at least four to five hundred birds gathered among the reeds on the islands and lakes.

In order not to disturb them, two bamboo rafts paddled slowly on the periphery of the lake, and several people looked at them with binoculars.

Director Cao observed the flocks of migratory birds in the air: "It's the red-headed gull and the wild goose, they should have just flown here and are getting familiar with the surrounding environment." ”

Ye Han also picked up the telescope and aimed his gaze at the sky.

The red-billed gull looks similar to a pigeon, and looks like it, with a light gray back and bright red beak and feet, and is also called a 'water pigeon'.

Dozens of them fly together in the sky and are common winter migratory birds in W City.

The other flock is nearly 100 geese arranged in a neat row.

The wild goose is what we often call the wild goose.

Wild goose is the common name of birds of the subfamily Wild Goose, in addition to the wild goose, the common ones are white-fronted goose, bean goose, bar-headed goose and gray goose, etc., they are all called wild geese.

Wild geese, it seems to be very common to hear the name.

However, people mostly see them flying in groups from high in the sky, and rarely observe them up close.

At this time, Ye Han happened to have this opportunity.

The wild goose is larger than she expected, with a body length of 80-90 cm and a wingspan of nearly 2 meters, making it a large migratory bird.

They fly with an elongated neck and broad wings, which makes them a bit bulky, but they are actually expert pilots.

Like whooper swans, it can fly up to tens of thousands of meters in the air and cross Mount Everest.

Director Cao: "The size of the wild goose is similar to that of the domestic goose, which is the ancestor of the domestic goose, and some people also call them wild geese. At present, it is a national second-class protected animal.

Due to ecological damage and overhunting, the population has declined significantly

Fast, it has only gradually recovered in recent years. ”

Protections are now in place.

Last year, he saw thousands of wild geese migrating in flocks in the Luanhu Wetland Reserve, and the scene was spectacular.

Ye Han's gaze moved as they flew.

As the book says, the word 'one' is arranged for a while, and the word 'person' is arranged for a while, like a gray line extending in the sky, maintaining a beautiful formation at all times.

This formation allows them to constantly gain upward air currents, saving them energy for flight.

And the change of formation is to change the position of the head goose.

Because the head goose is at the front, it cannot receive the blessing of the air current, and needs to bear more pressure, so it needs to be replaced frequently.

The wild goose is a very united bird.

They always move in groups, and when flying, they encourage each other to spend more than a month together.

Ye Han watched them fly in the direction of the artificial lake, making a large circle over the flower set, and then flying back in groups after a few minutes, making a loud 'quack' chirp from their mouths, as if they were inspecting and discussing the environment.

When they returned, they flapped their wings and landed in large numbers on the edge of the island in the middle of the lake.

Nearly 100 large migratory birds landed, and the scene was quite spectacular, with water droplets splashing and reeds shaking as they glided, and the birds in the bushes were startled.

It's really a big group, almost half of the lakeside area is occupied.

They may swim near the reeds, pecking at aquatic plants with their heads down; Or find a place to rest on the shore, and there are a few special ones to go to high places to 'sentry', and cooperate tacitly.

It seems to be preparing to spend the winter here.

Director Cao said to the observer next to him: "The ethnic group of this batch of wild geese is not small, pay attention to the number of records." ”

Observer: "Yes, Director. ”

Another batch of nationally protected animals has settled in.

There is an urgent need to establish a bird observatory in Huajianji.

Director Cao couldn't help but sigh.

Before he came, he had never expected such a scene.

According to Director Ye's explanation, the area of the island in front of him is only about 2,000 square meters, and it has become a habitat for migratory birds to come here.

If you don't see it with your own eyes, it's unbelievable.

Equally thought-provoking.

Why do migratory birds migrate thousands of kilometres to the south?

There are many opinions in the scientific community on this topic.

However, in Director Cao's view, the cold is not the main reason.

Like swans, they have thick fat in their bodies, can resist the cold of -30 degrees, and can move freely even in the north.

The most fundamental reason is that the lakes freeze in the north in winter, and food is scarce, making it difficult to survive.

It's all about survival.

He thought of the shiny cormorant that had just landed on the raft.

He had studied wild birds for several years, and had never seen one so brightly feathered and so large.

You can imagine how nourishing it is.

When it comes to next year's courtship period, it will definitely overwhelm the males and successfully win the attention of the females.

For birds, survival and reproduction are precisely the most important things.

There are also the swans, all of which prove that the environment here is suitable for birds.

This time I came to the flower fair

The survey is meaningful. ()

Not only have a variety of wild protected birds been discovered, but also the importance of protecting the ecological environment has been demonstrated.

As long as the ecological environment is good enough, birds will naturally make their home here.

No human intervention is required.

In the following time, among the reeds and metasequoia forests, many duck birds were observed: such as spot-billed ducks, green-winged ducks, ribbed ducks, red-winged ducks, mallards, etc.

There are not many of them, most of them are gathered together, dexterous and agile, and they disappear in the blink of an eye.

The spot-billed duck is often referred to as a wild duck.

They can also be seen in man-made lakes and swan lakes, but wild spot-billed ducks tend to stay far away from people, mostly shuttling through the reeds, and even if they are spotted, they will swim away quickly, and visitors can only see a circle of ripples on the surface of the lake.

It is a migratory bird, but a few have already made their home in Hanamaji, and it is expected that a cute baby duck will be born next year.

In addition, Ye Han also observed four precious white mergansers under the guidance of Director Yuan.

They are in the same parallel area as the ribbed duck colony, blocked by seven or eight ribbed ducks, swimming in the adjacent two rows of fir trees, and they are completely unclear without looking closely.

Fortunately, the telescope is expected.

Ye Han adjusted several times before observing.

It was the first time she had seen this cute duck, and it was so distinctive.

The male bird is black and white, with a white head, but the eye area is black, as if he is wearing a black blindfold.

Its color is the same as that of the giant panda, and it is particularly cute, so everyone also calls it 'Panda Duck'.

The white merganser duck looks very clean, with a pure white body color, only a few markings on the back and abdomen, as if wearing black suspenders, and is full of style.

The front chest is bulging, and the head forms a shrunken S-shape, and the body is beautiful, elegant and beautiful.

When Ye Han observes, it will dive underwater to forage for food as it swims, and then come out with a small fish or aquatic grass in its mouth.

The personality is very lively

。

When they float on the surface of the water, they reflect the clear water and clear waves in the forest, like elves shuttling through the forest, vivid and beautiful.

Ye Han couldn't help but sigh, his appearance was so high.

It's beautiful and comes with its own cute attributes.

The females next to it are not as good-looking as the males.

It also has a black eye patch, but the body surface is mostly maroon, not as distinct as black and white.

However, in nature, it is often the male bird that is more beautiful.

In order to succeed in courtship, they have to show off their gorgeous feathers, show off their dancing posture, and so on.

Director Cao introduced: "The white merganser duck, also known as the spotted merganser duck, is a national second-class protected animal.

There are not many observations in W City, but there are many people who like it, and every time I find it, a large number of bird-watching enthusiasts come to take pictures.

If you look closely at the crown feathers on the top of its head, it will change back and forth with the swimming style. ”

Ye Han immediately picked up the telescope to observe and found that it was indeed the case.

When the male looks around, the white crest of feathers is erected; When he was about to dive down, the crown was retracted.

Due to frequent diving, its crest is erected for a while, retracted for a while, erected again for a while, and so on.

Ye Han couldn't help but laugh, this is too cute, right?

() Isn't it afraid of wetting the plush plush plush on its head. ()

Perhaps for birds, the crest has an extraordinary significance.

She was observing, and Director Yuan next to her suddenly stood up, and even shook the bamboo raft a few times, but fortunately, there was a boatman to stabilize it.

"Lao Yuan, what's wrong?"

"Look at it, it's not a Chinese merganser over there!" Director Yuan's tone was visibly excited.

Director Cao was stunned for a moment, and said excitedly: "Where, you can show me quickly." ”

"Near the reeds on the right-hand side of the island in the middle of the lake, behind two little egrets, mixed with a dozen ordinary mallards, two on the left. See? ”

Director Cao focused on observing in that direction for a long time before finally confirming: "Yes, it really is!" ”

It is really a national first-class protected animal - Chinese merganser duck!

Both of them were irrepressibly excited.

This is the first time that this rare and endangered bird has been discovered in W City, which is of great significance.

Seeing that the two were swimming farther and farther, Director Cao hurriedly said, "Xiaohong, give me the equipment quickly." ”

He wants to do a good job in the preservation of data, this is definitely the most significant discovery of the bird observatory of the Forestry Bureau this year!

The Chinese merganser duck can generally be called 'China', and its status is not ordinary.

For example, the Chinese leek, a national first-class protected plant, appeared hundreds of millions of years ago as a "living fossil", known as the "plant giant panda".

The Chinese merganser duck is endemic to China, a remnant species of the Tertiary glacial period, which has been breeding on the earth for more than 10 million years, and is the oldest wild duck in China.

It is a national treasure on a par with the giant panda, the South China tiger and the Yunnan golden snub-nosed monkey, and is known as the "living fossil in the water" and "the giant panda in the bird". ①

The Chinese merganser duck population is extremely rare, with less than 1,000 remaining in the world at the end of the last century, and it is critically endangered. After years of conservation, the current number is around 2,500.

The relevant departments attach great importance to each discovery, and each discovery will be recorded and reported to the State Forestry Administration and the wildlife protection department to take corresponding protection measures.

What an exciting thing it is to find the Chinese merganser duck in W City today!

There has never been a record of this for so many years, but I didn't expect to see it in the Flower Collection today.

Director Cao's hands were a little unsteady, but fortunately, they were successfully filmed.

This is only a preliminary confirmation, in order to ensure the authenticity and accuracy of the information, they need to confirm many times and repeatedly, and get enough information to report.

It's a big deal, after all.

It is the most important piece of all the work this year!

Because the two 'national treasure ducks' were too far away, Ye Han did not observe them, but she saw the photos taken by Director Cao.

It's a pair, and the color of the head is different.

Males have black heads and necks, females are tan, and the most prominent is the long crest of feathers on the top of their heads.

Director Yuan also followed: "This is the unique symbol of the Chinese merganser duck, with double crown feathers, shaped like a crested head. ”

In Ye Han's opinion, the two tufts of feather crowns have a fluffy feeling after washing, cutting and blowing, which is very distinctive.

It's kind of cute.

Director Yuan: "There's another way to identify them, you look here, the feathers above their abdomen have black scales. As in the case of "auspicious."

() clouds" pattern, which has an excellent meaning. ”

Ye Han nodded, these characteristics were indeed not seen in other birds.

It's enough to prove that it's special.

The Chinese merganser is a large duck with a body length of up to 60 cm.

They are said to be very capable of flying and diving, and they are not weak in vigilance, but the destruction of their habitat still makes them endangered.

Fortunately, the relevant state departments have set up nature reserves in both breeding areas to protect the wintering areas, study their living habits, and help them reproduce, and now the number is recovering.

The discovery of the Chinese merganser duck lifted the spirits of the group.

It felt like buying a lottery ticket and winning the jackpot, and the excitement was spreading from the inside out.

For the people at their bird observatory, there is nothing more exciting than discovering rare and endangered birds.

Director Cao immediately decided to take a few observers around the back of the metasequoia forest to observe and continue to record data.

Director Yuan and Ye Han continued to observe the wild birds on the island in the middle of the lake.

By the end of the morning, they had observed more than 50 species of birds, with more than 500 individuals.

Among them is the national first-class protected animal: the Chinese merganser duck.

There are more than 10 species of national second-class protected animals: whooper swans, mute swans, whooper swans; Little Egret, Middle Egret, Great Egret; Blue-throated song robins, wild geese, white mergansers, etc.

The abundance of birds in this aquatic forest is staggering.

The migration of migratory birds is generally from October to December, and the current arrival can only be regarded as the first batch, and there will be a large number of migratory birds in November and December, and I don't know if there will be more species at that time.

But now there are quite a few of them, and almost every tree is inhabited by birds.

A few people found an open place to continue observing.

The largest number of egrets on the island are still birds, with pure white feathers, the big one is very obvious, and the egrets distributed in the metasequoia forest must have more than 200 individuals.

Some small finches hide in bushes or low branches and are not easy to spot.

Ye Han saw a small bird looking around on the reed pole, a little bigger than a sparrow, a fat one.

It has a long tail, a ring of black 'blindfolds' around its eyes, a brownish-red back, and a white belly, and it looks cute and pretty, and is chirping with its mouth open.

Probably passerines are all such fluffy fat chirps, cute, and very harmless.

However, this is just a completely different story.

Ye Han recognized it.

This cute little bird is a brown-backed shrike known as the "butcher bird", a small bird of prey among the finch.

Just as he was thinking, the brown-backed shrike standing on the reeds suddenly swooped down and held down a palm-sized frog between the stones with great speed.

The frog was an adult, large in size, and began to struggle desperately, only to be pierced through the neck by its hook-like beak.

It lifted the frog in its mouth, and after shaking its head continuously, the other party completely stopped moving, and the lower two legs stretched out.

It's dead.

Ye Han watched as the brown-backed shrike bit the prey, flew back into the bushes with thorns, threaded the frog on one of the branches, and tore the frog's leg fiercely.

The scene was a bit bloody, and Ye Han shifted his gaze.

The thorny bush was its storeroom, and she saw that not far away seemed to be piercing a half-eaten sparrow?

In short, it has changed beyond recognition.

There was also prey on the other two branches, a bird of unknown breed, and a small lizard hanging from it.

So cruel.

It is worthy of being a butcher bird, a master of piercing.

It is also said to mimic the calls of other birds, attracting them to hunt them.

Ye Han glanced at it again, obviously it looked so cute, a big fat plush chirp, and it turned out to be so fierce.

What a bird!
