After free time, everyone has time to see this archipelago, the sky is blue and the water is clear, it is a good place to travel.

On the beach, you can see a flock of seabirds, all meticulously digging their long beaks deep into the water, looking for food, which is very interesting.

"What kind of bird is that?" Cao Da asked.

This time, even Wei Hai shook his head, saying that he hadn't seen it.

Wei Hang spoke: "That's called the stone owl, a kind of migratory bird." ”

The stone owl is a common transit bird on Taiwan Island, but it is easier to see it during the spring transit period.

This seabird prefers to inhabit wetland environments such as intertidal zones, estuarine swamps and reef coasts, and can often be seen walking in small groups on the beach, constantly turning over rocks or shells with their beaks along the way, feeding on small animals such as silkworms and crabs hiding underneath. They look like they are rummaging through the rocks one by one, and they look like police officers in the middle of the case, carefully searching for clues hidden behind the stones, which is really interesting!

"It's going to change color in the winter. Wei Hang added.

The stone owl is short and fat, and looks very funny. They stand out for color during the breeding season, with a mix of maroon, white and black, and orange-red feet that easily attract attention, and in winter, the maroon color disappears in favor of a drab and modest dark brown coat.

"Nature is amazing, feathers can change color. "Muzi and the others felt incredible.

Like chameleons, it is not surprising that the skin changes color, and so do people, blush when they are embarrassed, turn blue when they are angry, and so on. But feathers are different, just like human hair, if it is not dyed, it will turn red, cyan, and green for no reason, and I am afraid that it will immediately be regarded as a monster, right?

"What about the yellow one?" Cao Da pointed to a small bird perched on a branch. Dressed in yellow-white feathers, it looks beautiful.

"That's the Yellow Head. Wei Hai said.

"Yellow-headed heron, also known as cattle egret, to be exact. Wei Hang corrected. Yellow Head is the name of their place, not a scientific name.

"This bird doesn't eat fish. Wei Hai continued, finally having a chance to express his appearance, he rushed to answer.

"! Can seabirds not eat fish? Who are you fooling?" Yun Rulong unceremoniously debunked.

This time, though, he was wrong. This bird really doesn't eat fish.

"Why am I lying to you? If you don't believe it, forget it. You take a good look at it and see if it eats fish or not. Wei Hai was a little unconvinced, and he didn't believe what he said.

Wei Hang smiled and said, "Don't believe it. Cattle egrets really don't eat fish. ”

He told everyone that the bird was the only heron that did not eat fish and ate insects, but also preyed on other small animals such as spiders, yellow eels, leeches and frogs. It has formed an attachment relationship with domestic animals, especially buffaloes, and often follows the animals to prey on insects that are frightened by domestic animals from aquatic grasses, and often rests on the back of cattle, so it is called cattle egrets.

"You can see this bird in many places, and it's not very rare. ”

Everyone walked and watched. Daniel Zhang: They have already moved the turtle down. Then they were sent to the biological research center on the island.

There is a biological research center on the island, which is not very large and does not have many people.

The person who received them was a scholar in his fifties named Gu Yan. He is a professor at National Taiwan University, and at this time of year, he will come here for a month.

"Xiao Wu, prepare the tools immediately. He shouted.

I saw such a big leatherback turtle. He frowned, feeling sorry for the sea creatures. Because of human activity. There are too many creatures that are also shot while lying down.

Alas, many turtles are caught and injured by mistake every year. This year, more than a dozen fishermen brought turtles and hawksbill turtles over. Professor Gu said.

Some sea turtles were caught in fishing nets, and many were injured because of the pulling of the fishing boats and the struggle to get out of it.

This turtle was obviously injured by mistake. If someone really wants to kill it, it's not there that it's hurt.

"Professor, how old do you think this turtle is? It should be hundreds of years old, right?" Wei Hai asked.

Professor Gu glanced at Wei Hai and said with a smile: "You young people, you are curious about this information all day long. Although sea turtles live a long life, they are not so exaggerated, and they have a lifespan similar to that of humans. Leatherback turtles are generally sixty or seventy years old, and the longest-lived turtles are more than 100 years. ”

Sea turtles can live up to 152 years, making them a well-deserved longevity among animals. It is precisely because the turtle is a long-lived animal in the ocean, so the people along the road still regard the turtle as a mascot of longevity, just as the mainlanders regard the pine crane as a symbol of longevity, and the people along the coast also regard the turtle as a symbol of longevity, and there is a "10,000-year-old turtle".

But it's not that turtles can live for hundreds of years, or even thousands of years, tens of thousands of years. They themselves have a stronger reproductive ability than humans, and there are many in one litter. If you could live that long, wouldn't the earth be full of turtles?

However, it is sad that this leatherback turtle has been asserted that it may become extinct within twenty or thirty years!

"Professor, you see there's something on it, what?" someone asked.

Wei Hang was also stunned, he hadn't paid attention to it before! He knew what that thing was, just a sign, a sign of being released.

Professor Gu glanced at it and said with a smile: "This turtle swam from the UK. It was a sign that someone had been caught in England and then released. ”

Daniel Zhang and the others widened their eyes when they heard this, this turtle is a cross-border tour, right? How far is it from the UK to here, they don't know, they haven't been to the UK, in short, it's half the world!

"Hehe! I'm surprised! It's amazing! I can travel around the world. Professor Gu suddenly smiled.

Leatherback turtles are pelagic creatures that inhabit mainly the pelagic of tropical seas, and are occasionally found in offshore and bay areas. Because of its large limbs and paddle-shaped, it can swim in the ocean for a long time and quickly, so it is called a "strong swimmer".

In addition, the turtle's sense of direction is very good. As the old saying goes: an old horse knows the way, but you may not know that the turtle has a stronger ability to recognize the way.

Sea turtles often follow migratory routes in the upper layers of the coastal waters, returning to their "homeland" in groups during the breeding season, where they can find their birthplace and lay their eggs, no matter how far away.

However, if the environment of the birthplace is destroyed, it is possible that it will be sterile for life. This is the biggest headache for their biologists, and in order for them to reproduce, you have to even change a place, which is very difficult.

"Alas, this animal will soon become extinct. If you see them in the future, don't disturb them. Professor Gu reminded.

"Since it's a protected animal, we definitely won't catch it. ”

"Well, that's good! You must pay attention to moderation when fishing. Now that there are more and more fishing boats, many marine life is threatened. Professor Gu said.

Despite the size of the ocean, fishery resources are also limited, and sooner or later seafood will be depleted without restraint.

He hopes that this younger generation of fishermen will fish scientifically, so that some marine creatures have room to breathe, and man and nature can develop in harmony.

"We know, and that's what the old professors in the village say. Wei Hai nodded.

"The old professor of your village?" Professor Gu was slightly startled, listening to this young man's words, there are many experts and professors in biology in his hometown!

"Yes, there are a lot of professors like you in Tangjia Village, who spend all day studying what kind of water quality!

"It turns out that you are from Tangjia Village, and your place is famous. It is said that a large paleontological fossil site has been discovered, and it is not known how well it has been studied. Professor Gu asked his peers, but it wasn't very clear, it seemed that the group of guys intended to hide the news.

"Professor Gu doesn't need to be in a hurry, he will know soon. Tao Lao told me that it would be announced in a few days. I took a look at the pictures, and they were really spectacular, so you might as well go and see them when the time comes. Wei Hang said.

Professor Gu looked at Wei Hang deeply in surprise, this young man knows a lot! It seems that he has a good relationship with those professors.

"Tao Jinhua?"

"That's right, it's him!" Wei Hang nodded in the affirmative.

"Well, in a few days, I won't be here anymore. Check it out when the time comes. Professor Gu also nodded slightly.

The two exchanged contact information, and Wei Hang hoped that Professor Gu would inform him at that time, so that he could make arrangements and fulfill the friendship of the landlord.

After the treatment tools were moved out, Professor Gu had no time to chat with Wei Hang and them. Let them take care of themselves, and then deal with the turtle's injuries.

Wei Hang and his entourage watched the qiē here, what specimens and so on, and then left. Everyone did not leave the island immediately, but played here for half a day.

What's more, there is no boat on the dock side now, and a channel in and out of the pier is blocked by that fishing boat, and it is still being processed.

It didn't take long for a huge gondola to break through the sea and clear the waterway.

Then, some of the wounded who were not strict came to thank them. Especially the middle-aged man in the cab, without the oxygen cylinder given to him by Weihang, he may have fainted from lack of oxygen.

They also had some emergency life-saving products on board, but the situation at that time could not be found at all, and they were locked in the wheelhouse and could not get out.

"An official just came to discuss the matter of compensation. A crew member said to Wei Hang.

"How to compensate?" Daniel Zhang and the others asked.

"It's not bad! This time, the medical expenses and lost work expenses will be compensated. The fishing boat lost hundreds of thousands, and it was possible to buy a new one. We also lost tens of thousands of dollars in the seafood we caught, so let's not talk nonsense everywhere, especially those who come for interviews. The man said.

Yun Rulong and the others looked at each other and smiled, knowing that this would be the result.

Immediately after, everyone was ready to set off on the high sea. (To be continued......)
