It is never a simple matter to walk on the road for heaven. Gobl carried the ladder in great interest. Chen Song stepped on the ladder to check the bird's nest and found that there were indeed bird eggs inside, but after searching several bird's nests in a row, no cuckoo's eggs were found.

Of course, he didn't know what the cuckoo egg looks like, but he knew that the eggs laid by different birds were different in shape. As long as there were eggs of different sizes and abnormal appearances in the bird's nest, they were cuckoo eggs.

Angelina came to find him and saw him lying on the tree and was curious: "Hi Vince, what are you doing? Are you building a watchtower?"

Chen Song said: "No, I'm looking for Dujuan eggs."

He told Angelina his thoughts, and after hearing his words, the female policeman smiled and said, "You are too presumptuous. This method cannot be found in the cuckoo eggs, because the cuckoo species has a magical ability. They will lay eggs that are very similar to the host's eggs in the host's nest, including the color and size of the eggs will change with the host's eggs."

These words shocked Chen Song: "This scumbag actually has such skills? It's incredible!"

"But this is the fact, especially the most common cuckoo in Iceland is called the big cuckoo. They have particularly outstanding abilities in this regard. They are one of the top nest parasite experts in nature and can parasitize eggs in the nests of 125 species of birds." Angelina introduced.

Chen Song was dumbfounded: "This is really a family of families with a hundred families. Du Juan grew up eating a hundred families? Hey, Anna, how do you know these things?"

Angelina shrugged, "Because my grades in Nature Conservation Class in Police Academy are always a+, which is the ability we need to learn."

There are few criminal cases in Iceland, so the police's responsibilities go wrong. They want to investigate traffic violations, show their presence on Facebook and Twitter, plant trees and grass, and protect rare animals and plants, but they have not solved criminal cases.

Speaking of the excitement, she called Chen Song down and said in detail: "You have to know that Du Juan is a technical job to find adoptive parents for her children, not just to find an honest bird."

"First of all, the target nest they are looking for must have bird eggs that can imitate them. If they encounter fierce birds like golden eagles and turtles, it will definitely not work, and it will not work if they encounter swallows and hummingbirds. The size of the bird eggs is too big, so they cannot imitate them."

"Secondly, they are late birds, which means that their birds have to be fed by the female birds after hatching and cannot live independently. This is different from chickens and ducks. Once chickens and ducks hatch, they can follow the female birds to leave their nests. If the bird eggs are left in such a place, they will starve to death even after hatching."

"Then the other hand, the food of birds is similar to that of themselves. Cuckoos eat insects. If they are placed in the nest that likes to eat grass seeds and flesh, even if they feed the young birds every day, they will die soon."

Listening to Angelina's knowledge, Chen Song couldn't help but nodded: "What you said makes sense, but now you are useless to tell me this, right? Why don't you teach me what the cuckoo egg looks like?"

Angelina smiled and said, "How come it is useless? What I teach you now is how to find cuckoo eggs. You just need to find birds that match the three signs I mentioned, and then go to their nests to find cuckoo eggs."

"Yes, you can be targeted and you will get twice the result with half the effort." Chen Song suddenly realized.

But after suddenly realizing it, it was useless. How could he know which bird meets these three conditions?

This cannot be blamed on his ignorance. Who except professionals can know this knowledge?

As a result, Angelina knew that she was still confused. Angelina simply said, "Forget it, I'll help you. There are more than 20 birds in Iceland that are targeted at cuckoo birds, but the most common ones are forest rock trellis and big reed warblers."

Chen Song didn't know Lin Yanfeng and Daweiying either, but this time there was no need to bother Angelina. He had a search engine to use, so he took out his phone and opened it 100 degrees.

Enter the names of Lin Yanfeng and Daweiyan, and a series of contents quickly appeared on the mobile phone screen:

What are you using to hunt birds in the wild? Find Brother Sticker at No. 22, Wien Road. Brother Sticker outdoor supplies store welcomes you. This store has bows and arrows, crossbows, hunting rifles, and various outdoor traps. There is always one that can meet your needs.

Shocking! An Asian college student was sentenced to many years of prison for catching birds for sale. Is it a lack of legal system or a degradation of morality? For more information, please pay attention to the 100 accounts.

The plane crashed, I and the flight attendant, the next door, the school beauties and the company goddess fell on a deserted island. It is far from civilization and there are extremely scarce food. Fortunately, this is a bird island, and there are many kinds of birds that can be used as food. For others, this is hell, but for me who have learned to catch birds with my master since I was a child. As the only bird hunter on the island, the goddesses who used to be above the top had to crawl under my crotch in order to survive...

Looking at these contents, Chen Song was stunned: 100 degrees, you are, of course you are stupid.

He immediately changed the search app to Google. This time, after entering the names of Lin Yanfeng and Dawei, a series of entries and pictures appeared.

Chen Song clicked on the picture and found that the two birds looked very similar. They both had a brown body color, both of which were twenty or thirty centimeters in length, and they all looked honest. The overall image was very similar to that of the big cuckoo. No wonder they were chosen as the takeover bird.

After knowing these two kinds of birds, Chen Song wandered around the forest. He looked up at the bird's nest on the branches and branches. Birds kept hunting and flew out again. In this way, with his excellent eyesight, once a forest rock trellis or a big reed warbler appeared, it would be impossible to escape his eyes.

He would not immediately take action when finding these two birds, but instead left marks on the tree.

When he finished turning the forest, he asked Gobl to carry a ladder to pave the way for himself.

It was too early in early May, and many birds had just returned from traveling and had not spawned.

However, there are always some impatient or endocrine male birds. With their spacious and strong nests and beautiful feathers, they attract little female birds who are confused about the world and successfully complete gene transmission, causing the female bird to lay eggs.

The male birds were complacent for their quick, accurate and ruthless actions, but they did not know that they had become the earliest victims. The big cuckoos set their sights on these bird eggs, and after some observations, they laid their eggs in the bird's nest.

Chen Song looked at these bird eggs carefully and found that the similarity was extremely high. If he hadn't been honed by the 12306 verification code when he was scrambling tickets during the Spring Festival travel rush, he wouldn't have seen the clues.

The egg pattern of the big cuckoo is exactly the same as that of the Lin Yanshu. The difference is that it is slightly larger in size, but because the big cuckoo hides the eggs under the other eggs, the birds cannot detect the changes.

After finding the cuckoo bird egg, Chen Song took it away.

He showed Angelina: "There's good food tonight."

Angelina shook her head: "The cuckoo egg is not delicious."
