Pu Luo was silent for a long time, and some of them didn't have the intention to tell him that there was indeed sunken wood at the bottom of the lake, but it was all placed in the center of the lake for the fish to take shelter and create a landscape, and it was impossible for his old man's fishing line to be entangled there!

So, why is Lao Wu fishing here? It's a matter of climate.

The transition between winter and spring is a painful and happy time of year for anglers, when the water temperature is low and the fish are as lazy as in winter.

However, because of the low water temperature, the fish are not easy to nest and have a higher fault tolerance.

However, spring fishing has a difference from other seasons, that is, spring fishing, you fish small but not big.

This size does not refer to the fish, but to the area of the water, where the water area is small, the water temperature will heat up faster, and the fish will be more active, which is why there are more fish near the shore in the spring, because there is less water near the shore, and the sun is warm, not only the fish like it here, but also the plankton.

In places with larger water areas, the overall water temperature is still low, so fish tend to be in deep water, which is not easy to take the bait.

So could there be a more suitable place for fishing in the whole of Springs than their animal park?

The water area is not large, any fish can be seen, the scenery is safe, there is a canteen to eat, and the toilet is also convenient, and those who have fished here before have said that it is good, the key is that the director is still his fishing friend.

So Lao Wu came to him, but he never expected that the zoo would not allow fishing now, just when Lao Wu was entangled between desire and human nature, and Lu Wu was also a little embarrassed, Pu Luo proposed an idea.

They really don't let tourists fish, but they didn't say that they won't let the staff fish, if Lao Wu puts on equipment and plays the role of an NPC here, it will not be a friend of the director's privilege, but a benefit to the visitors of the zoo!

Lao Wu was also very excited about this event, he had never played such a novel game before, wasn't this what Cospler? His juniors have play, he understands!

So the two sides hit it off, and Lao Wu not only prepared a full set of equipment, but even the money for the eggs issued to the tourists was covered by him, which can be said to be a lot of money for fishing.

However, although Lao Wu chose the most suitable position to take the bait, although the cormorant fishing in the same position had already eaten and pulled and eaten several rounds, the strength proved that there were indeed fish under the head, because he had proved too hard, he had already eaten half full and began to spread his wings to bask in the sun, and Lao Wu, who had paid the most, still did not catch a fish.

If he doesn't catch a fish, he doesn't do anything, and if he doesn't move, he won't let the tourists find this Easter egg, and he won't be able to find this Easter egg......

Oops, Pu Luo is really worried about this event to the end...... No one really guessed it, did they?

The eggs in their exit area are ready, and they won't end up being called a scam, right?

After all, who would have thought that Lao Wu Zhen would be able to disguise himself so perfectly that he could be so perfect that he could confuse the real with the fake?

It's a big crisis!

"Don't worry about that." At the critical moment, it had to be the director of the park, and Lu Wu showed him a video he took in the morning, which was the picture of Lao Wu putting on his equipment and going to the bridge.

"If anyone doubts it at that time, you can put this video on the official account."

Pu Luo gave the director a thumbs up, feeling that the director who was planning for a rainy day was really a first-class master.

"So how did you come up with this principal, you didn't believe that Teacher Wu would be discovered in the first place, right?" Holding a small red flag and preparing to lead a group to explain, the little money breeder complained.

Lu Wu...... Lu Wu was silent.

Seeing this, Pu Luo also fell silent.

I feel so pitiful for some reason.

What broke the silence was a phone call to the director's office, Lu Wu's action to answer the phone was as fast as thunder, and I don't know if it was to cover up something, "Hello, Daishan Animal Park, yes, I'm Lu Wu, ah, I've seen your video...... Hey? ”

Lu Wu's unusual silence made Pu Luo, who was turning on the computer, turn his head to look at him, and then he saw that the principal's expression became more and more serious, and after a while, he nodded and said, "I will discuss this matter with Dr. Wang, please give me a call, and we will call you back after confirmation." ”

After hanging up the phone, Lu Wu turned on the computer WeChat and typed, and said to Pu Luo: "It was a call from a well-known cat rescue organization in our local area, they had rescued a cat with a broken spine that was paralyzed, which could not be cured from the perspective of Western medicine, and then saw that the acupuncture and electrotherapy of egg skin worked very well, so I wanted to come and learn it." So I have to ask Wang Qiangguo if this acupuncture method is their unique skill that can't be passed on or something. ”

Pu Luo blinked, and when he saw that the director had already communicated with Wang Qiangguo, he casually searched the Internet for this rescue organization, wanting to see their reputation, after all, medical disputes are very troublesome from people to animals.

Then as soon as he clicked on the other party's homepage, he saw that the background of their homepage was a big four words - the advantage is mine.

Pu Luo tilted his head slightly, pulled the page down with some confusion, and was shocked by the name of the latest video.

- "The Great Battle of the Lion Cat...... Family encirclement and anti-encirclement"

Wait, which lion cat is this lion cat family? Could it be the lion cat family he knew?

Pu Luo hurriedly poked in and took a rough look, and then he breathed a sigh of relief, fortunately, the other party was catching a large family of female lion cats, and the lion cats of the cat gang were males.

Wait, Pu Luo couldn't help but gnaw his nails, his mind was full of self-doubt, the lion cat of the cat gang...... Is it a male?

The other party's hair was too long, and he didn't look at it carefully at the time!

It's over, he's a little blind to the cat, and this coat color is the same, so it's a little hard to tell the difference.

Chapter 90

In spring, birds chirp.

In order to win the favor of their sweethearts, and to show off their happy life to the people around them, the birds rushed to make all kinds of chirps.

It sounds very pleasant to humans, just like humans will feel fashionable when listening to foreign songs, but once it is translated, it will ......

Beautiful spring~

It's breeding season again~~

Looking for a wife, looking for a wife, looking for a gift~

↑That's pretty much it. In April, the birds of the south have settled in the courtship war and are beginning to nest in peace, while the birds of the north are just beginning.

The director's previous efforts to place nests in various parts of the zoo were duly rewarded, and many of the migratory birds, who had only planned to come to rest halfway, began to think about the important things of bird life after they had had enough to eat.

One of the first to affirm the zoo's ecology was the mandarin ducks, which began to fight on the surface of the water a week ago, because of the small population, and this week the overall situation has been decided, and now they have entered the stage of finding tree holes to make nests.

And at this time, you can see the character of the bird.

As soon as the reliable marriage proposal was completed, he took his fiancée to the hole in the tree where he had already stepped on it, and the big heart was still flapping his wings and stepping around.

Compared to the sweet courtship stage, there are more quarrels between the parents-to-be during this process, and sometimes the mother-to-be will do it when she is angry, and at this time, the male bird is always gray.

But it's not that the male birds don't work hard, the main reason is that the tree resources of Daishan Zoo are indeed not as in line with the preferences of mandarin ducks as the wild environment.

Mandarin ducks are small in size, and young birds are even more bite-sized for hunters, and even cute squirrels can catch themselves to supplement some protein, not to mention common natural predators such as snakes.

Therefore, in order to improve the survival rate of the cubs, the mandarin ducks will build their nests in very high old tree holes, and most of this kind of tree holes are the old nests of natural decay or squirrels, but the trees in Daishan Zoo are too healthy, not to mention tree holes, not even wormholes, and there are no squirrel holes.

Although I don't know the reason, just like Lu Wu said before, as soon as the weather warmed, the squirrels who had come to the zoo to eat before also returned to Mount Tai in the south.

But it doesn't matter, humans will take action.

Now it's time for the artificial nest to come out!

But—

"They don't seem to like the nest very much." Pu Luo stood under the tree and looked up at the mandarin ducks advancing in the artificial nest, going in and out of the artificial nest, and looked at Lu Wu, whose eyesight was not as good as his, and was holding the telescope at this moment with a slightly thoughtful look.

"Headmaster?"

"That's true......" Lu Wu thought for a moment and muttered, "Is the location inappropriate, or is the nest itself not suitable for mandarin ducks?" ”

So saying, he climbed up the tree and plucked the empty nest.

"Aang? Is there still a nest that is not suitable? Pu Luo, who squatted down to observe with Lu Wu, was a little confused, because he had the impression that there were all kinds of bird's nests in the world, and all other birds could share them except for their size.

"Is it too low?" Breeder Xiao Lu interjected.

"Not too hidden out there?" Breeder small money probe.

"Do you want to do a camouflage?" Breeders are less than to give opinions.

Pu Luo: "......" said, when did these guys come over?

Xiao Lu waved his hand and said that it didn't matter when they came, the key was that the mandarin ducks did not make a nest, and it was better to solve this problem first.

The keepers gathered around to brainstorm, and after some discussion, they wrapped the outside of the artificial nest and hung the branches on a higher ground, but the truth was still not satisfactory to the couple, and the truth was not revealed until Lu Wu consulted his friends who worked for a large non-profit nature conservation organization.

"The structure of your nest is more suitable for those birds that come out of the nest after full wings, not for mandarin ducks." As soon as the dark-skinned young man connected to the video and looked at the structure of the bird's nest, he smiled, "You know that mandarin ducks are arboreal, and as soon as the chicks are born, they will jump out of the hole and follow their parents to the pool, right?" ”

"Yes."

All the keepers nodded in unison, and they all hung their nests high, but the mandarin ducks still didn't come.

"You just don't care if it's dark under the lights, it doesn't matter if it's tall or not, and the mandarin ducks in the wild can't find holes of the right height in every tree, and they can do it when necessary, but the key is - you have to leave a way for the chicks to jump out!"

Yes, oh!

Pu Luo suddenly realized.

It was they who were dark under the lights, thinking only about the outside of the nest, but not about the inside.

If it is a tree hole in the wild, the interior is basically potholed and angled, and the cub's feet and small wings can go up the slope if they work together, but the artificial nest is made of wooden planks, and the internal burrs have been rubbed by careful keepers.

Presumably, this is also the reason for the hesitation of Mandarin Duck's parents.

Knowing why, it's easy to change, whether it's carving scratches on the "wall" of the board to increase friction, or sticking wooden strips to make it easier for the chicks' feet to borrow, it's not complicated to do.

In addition to the poor handiwork that was left untouched, it took everyone two hours to complete the renovation of the bird's nest.

Xiao Lu, who is the most skilled at the work, also took the opportunity to add a snake baffle to the nest, and then they spent the same amount of time hanging the nest back in place, while also installing three generations of small snowmen that can be charged by solar energy on the side.

By the way, while waiting for everyone to do carpentry, Pu Luo was not idle, and while installing special batteries for the little snowmen, he took out his paintbrush and painted camouflage uniforms for the little snowmen, which effectively prevented the birds from being disgusted with the surveillance.

Don't worry about the paint making the birds wary of the little snowman, God has also closed the door to their sense of smell after giving most of the birds the sight of the buff.

And the director has done a further job with the little snowmen - they are labeled with small leaves, which at first glance look more hidden.

Taking into account the habits of mandarin ducks, the zoo keepers also carefully selected some locations with dense vegetation on the ground when placing the nests, so as to cushion the nestlings that jumped down.

After all of this is done, all that remains for them is to observe and document.

It is gratifying that on April 2, 1/3 of the artificial bird's nest was updated to a nest style suitable for mandarin ducks, and on April 3, a couple of mandarin ducks chose to move in, and the tenants were scattered in the following week, until the Qingming Festival holiday, the mandarin duck couples in the zoo basically found their nests.

By the way, there is a pair of mandarin ducks that still don't seem to like artificial nests, and as the most powerful couple in the group, they have found the only tree hole in this zoo - the old nest of Qinyuan.

That's right, it's the one where the Pu Luo Weasel occupies the nest.

"That's not good." After discovering that the couple had taken that position, the keepers stood under the tree and began to observe.

The tree is well located and at the right height, and its southwesterly orientation both shelters from the cold winds and effectively prevents rainwater from entering under the southeast monsoon, but it has a drawback.

It's located below...... There is a large concrete floor.

Within the range of possible landing of the chicks, the proportion of cement and earth is almost eighty-two points. If you add in the probability that the chicks will drift due to the wind direction when they land because they are too small, it is almost impossible for the little mandarin ducks to fall smoothly on the soft ground.

"What can I do about this...... Pick up a trampoline down to the bottom? ”

"What if we dig the nest directly?"

"This is not good, the mandarin duck has a probability of abandoning the nest, and it is too troublesome for the chicks to intervene manually for only one day, and the key is that you have to be able to go up to such a high tree."

"Good fellow, I didn't even notice that there was a tree hole up there at this height!"
