Walking for the sky is never a simple matter, Goble carried the ladder with great interest, Chen Song stepped on the ladder to check the bird's nest, and found that there were really bird eggs inside, but after looking for several bird's nests in a row, he did not find the cuckoo's eggs.

Of course, he didn't know what cuckoo eggs looked like, but he knew that different birds laid eggs with different shapes, and as long as there were eggs in the nest that were abnormal in size and shape, they were cuckoo eggs.

Angelina came to him and was curious to see him lying on a tree, "Hey, Vince, what are you doing?

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

He told Angelina his thoughts, and the policewoman smiled at his words, and said, "You take it for granted, you can't find cuckoo eggs with this method, because cuckoos have a magical ability, they will lay eggs in the host's nest that are very similar to the host's eggs, including the color and size of the eggs will change with the host's eggs." ”

Chen Song was shocked by these words: "This scumbag bird has such a skill?

But it's true, especially since Iceland's most common cuckoo is called the Great Cuckoo, and they are particularly good at this, being one of nature's best nest parasitists, able to parasitize their eggs in the nests of 125 species of birds. Angelina introduced.

Chen Song was dumbfounded: "This is really a family of 100 families, and the cuckoo grew up eating 100 family meals? Hey, Anna, how do you know these things?"

Angelina shrugged and said, "Because my grades in the Nature Conservation Class in the Police Academy are always A+, which is what we have to learn." ”

With fewer crimes, the police have a wrong role to detect, to show their presence on Facebook and Twitter, to plant trees and grass, to protect rare animals and plants, but they have not solved criminal cases.

Speaking of Xingtou, she called Chen Song down and said carefully: "You have to know that cuckoos find adoptive parents for their children is a technical job, not just an honest bird." ”

"First of all, the target nest they are looking for has to have eggs that they can imitate, if they encounter birds of prey such as golden eagles and buzzards, it will definitely not work, and even more so swallows and hummingbirds, the eggs are too different in size for them to imitate. ”

"Secondly, they are late adults, which means that their chicks hatch and are fed by the mother bird and cannot live independently. This is different from chickens and ducks, where once hatched, they can follow the mother out of the nest and will starve to death if the eggs are left in such a place. ”

"The cuckoo eats insects, and if it is put into a nest that likes to eat grass seeds and pulp, even if the bird feeds the chicks every day, it will not be long before they die. ”

Listening to Angelina's eloquent knowledge, Chen Song couldn't help but nodded: "What you said makes sense, but it's useless to tell me this now, right?

Angelina smiled: "How can it be useless? What I'm teaching you now is how to find cuckoo eggs, you just have to find the birds that match the three signs I said, and then go to their nests to find cuckoo eggs." ”

"Yes, it's targeted, and you can get twice the result with half the effort. Chen Song suddenly realized.

But after suddenly realizing it, it was still in vain, how did he know what bird met these three conditions?

He can't be blamed for his ignorance, who can know this knowledge except professionals?

As a result, Angelina knew, seeing that he was still confused, Angelina simply said: "Forget it, let me help you, there are more than 20 species of birds in Iceland that are targeted by cuckoo birds, but the most common are the forest pipit and the reed warbler." ”

Chen Song didn't know Lin Yanpian and the big reed warbler, but this time he didn't need to trouble Angelina, he had a search engine to use, so he took out his mobile phone and opened it 100 degrees.

Typing in the names of Lin Yanpipit and the Great Reed Warbler, a flash of content quickly appeared on the phone screen:

What do you use to hunt birds in the wild? Welcome to Brother Stick Outdoor Shop, we have bows and arrows, crossbows, shotguns, and a variety of field traps, there is always one to meet your needs.

A college student in Asia has been sentenced to prison for many years for catching and selling birds, is it a lack of legal system or a moral decline? For more information, please pay attention to the number of 100 companies.

In the plane crash, I fell into a desert island with the flight attendant, the little girl next door, the school girl and the company goddess, which is far from civilization and extremely scarce in food, but fortunately this is a bird island with many kinds of birds that can be used as food. For others, this is hell, but for me, who has been learning to catch birds from my master in the mountains since I was a child. As the only bird-hunter on the island, the goddesses who used to have their eyes above the top had to crawl under my crotch in order to survive......

Looking at these contents, Chen Song was suddenly stunned: 100 degrees, you hold it, of course, it is a stupid mouth.

He immediately uninstalled the search app and replaced it with Google, and this time after typing in the names of Lin Yanpian and the big reed warbler, a series of entries and pictures appeared.

Chen Song clicked on the picture and found that these two birds looked very similar, both had a brown body color, both were twenty or thirty centimeters long, they both looked honest, and the overall image was very similar to the big cuckoo, no wonder it was chosen as the receiving bird.

Knowing these two birds, Chen Song walked around the forest, he looked up at the nest on the branches of the branches, and the birds kept coming back from predation and flying out, so that with his excellent eyesight, once a forest rock pipit or a big reed warbler appeared, it would definitely be difficult to escape his eyes.

When he finds these two birds, he doesn't do it right away, but leaves a mark on the tree.

When he had finished turning the woods, he asked Goble to carry the ladder and pave the way for himself.

It was still early in May, and many of the birds had just returned from their trip and had not yet laid their eggs.

However, there are always some male birds with impatience or strong endocrine habits, and with the help of large and sturdy nests and beautiful feathers, they attract and confuse the little females who are not familiar with the world, and successfully complete the genetic transmission, so that the females lay eggs.

The males were complacent about their quick and precise attack, unaware that they were the first victims, and the cuckoos set their sights on the eggs, which they laid their eggs in the 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 verification code of 12306 when he was grabbing tickets for the Spring Festival before, he really couldn't see the clues.

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

When he found the cuckoo egg, Chen Song took it away.

He showed Angelina, "There's a meal tonight." ”

Angelina shook her head: "Cuckoo eggs are not delicious. ”

Chen Song said: "It's not delicious? I'm afraid you don't know the deliciousness of hillbilly quail eggs! I mean, even quail eggs born from feed can be made so delicious, let alone wild bird eggs?"
