The next day, when Ye Han went to receive the staff of the Wildlife Conservation Association, he found that there were quite a few people coming.

In addition to Director Yuan Honglin and two members of the association, who had met before, there were also three people from the Bird Observatory of the Forestry Bureau, and a group of 6 people came to Huajianji.

Yuan Honglin: "This is Director Cao of the Wild Bird Observatory, they are the competent authorities, and they will work with us to explore the species and numbers of birds." ”

Ye Han shook hands with him: "Hello, I am Ye Han, the director of the Huajian Botanical Garden, and I am glad to meet you." ”

Director Cao's eyes showed a slight difference, but he didn't expect that the young girl in front of him was the principal.

It's no easy task to manage a large botanical garden, but he doesn't show that surprise.

Director Yuan was obviously very familiar with this place, and said to the group: "Let's go, let's go and see last year's batch of wild swans first." ”

Everyone took a sightseeing bus to Swan Lake.

Along the way, the plants are lush, and the tall evergreen trees on both sides are still verdant, and the small flowers are brilliant and colorful, making it a vibrant scene.

The botanical garden covered with plants and trees is full of greenery, the air is extremely fresh, accompanied by the sweet fragrance of osmanthus flowers, which makes people's mood gradually calm, as if entering a paradise.

Director Cao and his entourage had only heard of the name of Huajian Ji, and it was the first time they came here, and they couldn't help but be attracted by the environment of the botanical garden.

What they see is ecology.

The ecology here is almost natural.

I didn't see any pollutants and garbage along the way, it was clean and tidy; The trees are luxuriant, and the leaves are bright and green as if they have been washed in water.

Walking through the road, I often hear the sound of insects and birds chirping on both sides, and when I look up, I can faintly see the nests built on the branches of trees.

If I didn't know that this was a botanical garden, I would have entered a nature reserve.

Surprisingly well protected.

Director Cao couldn't help but glance at Ye Han.

The flower collection is now very popular, and the circle of friends is a photo of going to check in and travel, and it is very famous in W City, and it has topped the popularity list many times.

Originally, they thought that the number of visitors received every day would be so large that the environment in the park would inevitably be affected.

There are some worries about the living conditions of wild birds.

However, the view in front of me was completely unexpected.

Each of the flowers and trees has been carefully cared for and grows vigorously, and some trees have been carefully pruned; The flowers and vegetation on the roadside also show no signs of being spoiled by random picking.

There is no garbage on the ground, and even the fallen leaves have been swept clean, and it is completely a pristine ecological environment that has not been trampled by humans.

And it's very, very hard to do that.

Even in national parks, it's not uncommon to see dry branches, wilted plants, and debris scattered in the grass, which is inevitable for a vast area.

How does Flower Between the Sets do it?

Just thinking about it, the sightseeing car came to the artificial lake area.

Director Cao saw the clear water of the lake, which was as clear as a mirror, and the visibility was extremely high, and even after a distance of more than ten meters, he could faintly see aquatic plants and other aquatic plants floating below.

Not far away, more than a dozen white swans fell from the sky, folded their wings and flapped the water, and then landed near the reeds.

they

Floating on the mirror-like surface of the lake, the feathers are as white as snow ⊿ ()_[()]⊿『Come []#看最新章节#完整章节』(), clean and tidy, the feathers on the outside of the back are upturned, fluffy and shapely, showing an elegant posture.

Then, several of them jerked their long necks into the water, plunging their entire upper bodies into the water in an upside-down posture.

When you catch algae and aquatic plants, you quickly surface your body, stretch your neck and swallow it with your mouth thrown in your mouth.

On the way, I screamed happily a few times, obviously quite satisfied with the food.

The droplets of water on the feathers are gracefully shaken off by them, and they regain their fluffiness, and so on.

Whooper swans eat about a kilogram of aquatic plants every day, so they forage more often.

Director Cao saw this scene and asked, "This is one of the populations of wild swans?" ”

Ye Han replied with a smile: "No, director, this is the white swan artificially bred in our botanical garden." ”

"Captive-bred?" Director Cao looked at the happily foraging creatures in the lake with some surprise.

It is nothing more than that he would be mistaken, and most of the artificially bred swans have lost their ability to fly after many generations of cultivation and domestication. It's like a pheasant can fly to a height of more than ten meters, but a farm chicken can't fly at all.

What's more, the swans in front of you are larger than propagules, with amazing wingspans, plump plumage, and will find food on their own, without artificial feeding.

Except that migratory birds do not migrate, isn't it the same as the wild ones?

It's a whole new way of raising and it's worth learning.

The observers he brought with him began to record the number of such second-class wild protected animals from just now.

Hearing that it was artificially cultivated, I couldn't help but be stunned for a moment, and made a separate mark on the back.

They had been observing and researching for several years, and it was the first time they had seen such a vigorous domestic swan.

A line of egrets flew through the air, a dozen of them lined up in a line, and soon disappeared into the metasequoia forest, without a trace.

As soon as they entered the flower fair, they had already met two protected animals.

Director Cao predicts that the next investigation may bring them a surprise.

*

When the sightseeing bus arrived at Swan Lake, the group got off the bus and walked to the shore for a closer look.

The number of swans in the park has now doubled compared to last year.

During the breeding season in May, a total of 4 pairs of swans □□ one after another, and with the addition of baby swans born in March, the group increased by 23 to nearly 50 individuals.

After half a year of growth, these juvenile swans have lost their fluffy fetal feathers in their juvenile years, and have become almost as large as their parents, and are able to live independently.

It's just that there is still a gap in the fullness of the feathers, and it looks more immature.

Seeing Ye Han coming, the swans playing in the water gathered towards the lake, and the soles of their feet moved, causing ripples on the surface of the lake.

Several young black swans of relatives were the first to swim over, stretching their necks and rubbing her legs and palms affectionately, and even flapping their wings to hug her.

Not to be outdone, four or five of the other white swans flew to the shore and surrounded Ye Han.

At this time, the swan has long since disappeared from the arrogant appearance of other tourists feeding on the shore, and she is more enthusiastic when she sees her than when she sees the keeper.

Director Cao and his entourage looked at this scene of friendship and smiled.

This is a picture of the harmony between humans and animals, which is commendable.

() Ye Han rubbed their beaks with the palm of his hand and stroked the fluffy feathers, but he really didn't want to hold them, it was very heavy.

Just last week, the breeder Xu Guangyin just gave them a physical examination, and even the juvenile swans weighed ten pounds, and their weight increased rapidly, and they were fat and strong.

In just over half a year, it has grown into a goose.

Several wild whooper swans swimming nearby saw this scene and approached in this direction curiously, and the observers immediately took video footage and recorded it.

The number of wild swans arriving this year has also increased considerably compared to last year.

Ye Han calmed the swans and walked along the shore with the people of the Conservation Association, looking for wild swans hidden in the reeds.

"There are 1, 2, 3...11 on the deck, 14 swimming around, and there are several small groups in the reeds, so we take care not to disturb ......"

A group of seven people all used binoculars to scout the shore and hidden paths, keeping a certain distance from these wild birds.

On the way, the observers kept a record of where they were and how many they were.

Counting wild birds is not easy.

Large birds of prey like swans are fine, and other smaller birds are flying in large swaths in the air, constantly moving in the air; Or they can live on leafy branches and hide in tall bushes, which can be difficult to find and count.

Therefore, the Forestry Bureau will set up several observation stations in wetlands or parks where a large number of birds are infested, stand at a high place and use telescopes and other equipment to monitor in the open wetland, and use the sample point method and transect method to calculate the overall number.

There will be a certain amount of error in the data, and it takes long-term observation, continuous discovery and recording by the staff to improve the species and number of wild birds.

Ye Han was holding a 10x binoculars in his hand, and the observation with it was really very clear, the picture was pulled in several times, and he could even see the appearance of mute swans combing their feathers in the gap between the reeds.

After scattered statistics by several observers and conservation associations, conclusions were quickly reached.

Director Yuan: "The number of small swans initially observed is 26, an increase of 9 over last year; There were 21 mute swans, an increase of 6.

The amount is very impressive. ”

This should be the largest number of swan populations observed in W City as of October 30 this year.

As birds of prey, they are not numerous in groups, and adult swans tend to leave on their own.

Last year, a population of 66 whooper swans was observed in the Luanhu Wetland Ecological Reserve, the most in recent years.

Now, in the small water area of Huajianji, 47 wild swans have been observed!

As he said last year, it was a miracle indeed.

It shows that the ecological environment here is significantly better than other areas, and it is a very favorite habitat for swans.

And by comparing it with last year's group, it was shown that the adult swans who were supposed to leave also came with them, and they also brought their own partners to join, which made the group further grow.

The date of this year's migration is also half a month earlier than in previous years, and in addition to the influence of the climate, the environment here must also contribute to it.

Before the first time

Director Cao didn't expect the number to be so large at all.

He looked around, and the area here was a far cry from the thousands of acres of wetland parks and reserves.

But looking at the state of this group of wild swans, the feathers are smooth and shiny, the wings are broad and powerful, and when they are happy to forage, they flutter their wings, play with each other, or fly back and forth between several bodies of water, which is more comfortable than in the reserve.

It's an environment of their own choosing.

Director Cao asked the observers to make a record: "The little swan and the mute swan are both national second-class wild protected animals, and the number is scarce, and I hope that Director Ye will pay attention to protection."

When we go back, we will submit the information and report it to give some support to the flower collection to ensure that they can spend the winter safely here. ()”

Ye Han: "Okay director." (6) (6) [()] 『Come[]& See the latest chapter&Full chapter』()"

......

Departing from Swan Lake, the group headed to the Metasequoia Forest.

Coming in November, as the temperature drops, the metasequoia leaves are gradually turning red, and now only a small part, and by mid to late November, the entire metasequoia forest will be dyed red.

Walking on the forest plank road, you can clearly feel that the number of birds here is increasing.

The crisp sound of birdsong and fluttering wings echoes through the forest, and the reddish leaves of Metasequoia are reflected in the water, making the scenery as beautiful as an oil painting.

Even the staff who are often involved in field surveys can't help but be fascinated by the view.

The fluttering sound of wings sounded, and Ye Han picked up the telescope to observe, it was a small group of white-headed bulbuls (bei).

They have a small handful of white hairs on the top of their heads, also known as pulsatillas.

A dozen of them landed on low branches, with yellow-green feathers on their backs, gray and white chests, and graceful bodies, with thin claws moving around on the branches, sticking their heads out and looking at them curiously.

When it was time to shoot, they screamed a few times and quickly flew into the bushes below.

The bald bulbul is not uncommon in W City, omnivorous, eats pests in agriculture and forestry, and is a beneficial bird.

Ye Han was continuing to observe, and suddenly heard a pleasant chirp.

Gentle and melodious, with a thin voice, like a little singer, and other birds responded.

The others heard it too, and invariably lowered their voices.

The melodious birdsong is becoming more and more obvious, and a single chirp can turn several corners, and the tune is beautiful and tactful, and human beings are ashamed of themselves.

Gradually, the crowd found the source of the sound, and stopped at a certain distance to observe.

Ye Han searched the surroundings with a telescope, and found a few chubby birds in a small patch of reeds near Metasequoia, chirping with their mouths open.

That's them.

Ye Han locked onto the target and aimed at the bird to observe carefully.

The cute little guy is about the same size as a sparrow, and the body is small, and it looks round.

The most striking thing is that it has several rings of brightly colored feathers on its chest, the largest of which is bright blue, and there are orange-red and black-brown around it, like a fluffy colored scarf.

They are very cheerful to jump up and down among the reeds, stretching their singing voices, because they are very light, and they are still swinging on the reeds in the wind, very lively.

It's so cute.

Ye Han couldn't help but smile.

However, it didn't take long for them to seem to notice the arrival of a group of people, and quickly hid deep in the woods.

Director Cao put down the high-powered monoculars: "It's the blue-throated song robin (qú), a national second-class protected animal." It is similar in size to a sparrow, and is good at chirping and mimicking.

() Withdrawn by nature, often hiding in low shrubs or reeds, and leaving when the wind blows. ”

This is the third time that a protected animal has been observed.

Director Cao's heart fluctuated, but looking around, looking at the tall metasequoia on both sides and the clear lake, it was not unusual for the environment of this water forest.

The number of bluethroat song robins is difficult to determine, but four have been observed so far, but there are definitely hidden in the reeds and grasses in other areas, which requires more careful observation by observers along the way.

It is best to use equipment to detect from a high place, and the field of view is more wide.

Thinking of this, Director Cao already had an idea in his heart.

The group got on a bamboo raft, divided into two boats, and shuttled between several rows of cedar forests one after the other.

During this period, Ye Han also observed common birds such as turtle doves, brown-headed jays, cormorants, etc., all of which were raised with shiny feathers and a larger body than ordinary ones, which showed that the food was very good and they were not very afraid of people.

Cormorants, as medium-sized birds, unceremoniously stop in front of the raft and seem to rest in the human place.

It combed its feathers with its pointed beak, seemed to see a fish in the water, tilted its head, stretched its neck to observe for a few seconds, and then plunged into the water and splashed into the water, which naturally succeeded.

Fishing masters aren't just talking.

The observer looked at the video he had taken, and was a little stunned.

With the exception of ospreys, which are domesticated by fishermen, cormorants in the wild generally do not approach people and even attack humans when they feel threatened.

Such close contact is really rare, and it can be said to be an extremely valuable video material.

Perhaps in the eyes of the wildlife, this aquatic forest is their territory, and humans have just strayed into it.

Ye Han sat in the bamboo raft and saw a few kingfishers perched on rocks and branches by the lake, they can be described as the face of the bird world.

The small one is about 16 cm long, with a pointed mouth, bright and shiny feathers, very beautiful emerald blue feathers on the back, and spots of the same color on the head.

The chest is fluffy yellow-brown, the throat is white, and the black bean eyes are very cute, beautiful and cute.

It is precisely because of the beauty of the feather that it was used to 'dot emerald' in ancient times, and now this cruel craft has been completely banned.

The kingfishers are all lone rangers, and the few that Ye Han saw were in different places, only one of them was treated together, and the coat color should be a companion.

As he was observing, a kingfisher suddenly swooped down from a branch and plunged its whole body into the water, making a small splash.

In the blink of an eye, Ye Han had already flown back to the branch, and its pointed mouth was holding a small fish and shaking it constantly.

So fast!

Ye Han saw a kingfisher hunting for the first time, but he didn't expect a small one to be so powerful.

Director Yuan introduced on the side: "Don't underestimate the kingfisher, it is a ruthless character, with extraordinary fishing skills, and it can see its prey clearly in the water."

Some large kingfishers can even catch mammals such as snakes, small lizards, and mice. ”

It turned out to be a small bird of prey.

Ye Han really didn't expect it.

She continued to observe the kingfisher, because of its thin beak, it had to adjust the fish's head in the direction of it before it could swallow.

So it shook its head several times in a row, and finally swallowed this little fish into its belly, beautiful

Ate a meal.

However, within a few seconds, it was fishing again.

I didn't expect the small one to be quite edible.

……

In a short time, nearly 20 species of wild birds have been observed, many of which are nationally protected animals with rich species.

The most numerous of them are the egrets.

It's a paradise for herons.

Especially after leaving the boardwalk, two or three egrets perched on top of the tall metasequoia every other section.

Resting in the canopy of the trees, or landing on the rocks and stretching their necks to wait for the opportunity to move, or flying into the forest in a row, forming a beautiful picture.

Among them, there are seven species of egrets, including small egrets, medium egrets, great egrets, and pond herons, all of which are long-legged. The first three coat colors are pure white, with a slender posture and a fairy spirit; Other species such as pond herons are covered with gray or brown feathers, and their appearance is also very good.

But the best sight is of course the egret with its white feathers.

Seeing these egrets, both the Conservation Society and the Forestry Department were shocked.

There are at least 100 of them living in the forest, and I don't know when they gathered here.

Doesn't it mean that this metasequoia forest has only been built for less than half a year?

Now that it is not the breeding season, there are so many egrets settling here.

Except for two or three migratory birds such as the yellow-billed egret, the rest of the egrets are resident birds and do not migrate, which means that they will settle here for a long time.

And they are all national second-class protected animals, and their distribution range is not much.

Although there are hundreds of egrets in the Luanhu wetland, it was originally a nature reserve, and I don't know how many years of efforts have taken for these birds to stay here with peace of mind.

However, this is a botanical garden, not a dedicated habitat, and the metasequoia forest has attracted so many birds less than half a year after it was built.

It's amazing.

It also shows that the ecology here is extremely good.

Director Cao is ready to submit an application when he returns, hoping to establish bird observation points in the surrounding area to facilitate ecological research and bird statistics.

With the variety and quantity here, it should be approved soon.

Recall that there are more than 30 species of birds just observed, totaling more than 200 birds, of which no less than 10 species are protected by the state, accounting for more than half of the number.

It's already a small protected area.

When the rafts entered the wider area, they were shocked to find that the actual number was far beyond their estimates.

The birdsong in front of you is getting louder and even noisy, and you can see the various birds docked on the island with telescopes, and small groups of migratory birds hovering overhead.

This island in the middle of the lake has become a habitat for migratory birds!
