Chapter 752: The story of the mallard

Fang Ye said, "This kind of landscape pond is not used by birds, nor can other small animals.

As long as the pool is slightly modified, the edge is shorter, or a small **** is made with some small bulges that can stand on the inside, small animals can drink here, and perhaps there is more hope of survival.

A girl in Nanjing arranged two infrared cameras next to a small puddle formed after rain in a small forest near her home.

I asked people who have lived for five or six years before, and they all said that there are no wild animals here, at most there are rats and snakes.

As a result, after setting up the camera, I photographed brown-backed shrike, grey magpie, mountain dove, spot-headed owl, dozens of species of birds here to drink, bathe, play, and court. Yellow ferrets came here to forage, and a few months later they brought them. Come again with my family. In the middle of the night, a hedgehog was rummaging in the dirt for food.

Just beside the noisy road, with a few trees shaded by a little rain, there are so many small animals struggling to survive.

Although the scale of these ponds and green spaces in the city is small, the scale of many wild animals is also very small. "

"I have read this news too! I never knew there were so many wild animals in the city."

"Before, because of the epidemic, I picked up my camera and wandered around the green space outside the community. I photographed more than 30 kinds of birds! I never thought that there are so many natural elves in a prosperous big city."

"There used to be such a small puddle near my house. It was a paradise for butterflies, bees, toads and many other animals. Later, the hardened road was built and it was not so lively."

"In fact, the city does not need to be so regular, horizontal and vertical, with a **** at the edge of the pool, and some stones. This kind of vigorous ecological pool is better than a rigid landscape pool, whether it is a landscape effect or an ecological value. "

"There are white-headed bulbuls and magpies in our community. Sometimes they rest on the air conditioner outside the window. I made a bowl of water and put some water on it. I found fluff in it. Some birds came to drink water."

Netizens watched the little birds fly away contentedly and talked lively.

Fang Ye said again: "This is a story told by Teacher Wang Yan that happened on the campus of Peking University.

A young mallard mother took her newborn children across the campus, familiarized herself with the environment, and went to swim in the pond.

In the pond, the little ducks swim for the first time and have a great time.

But after half an hour, the mother mallard was about to go back to the shore, when something was wrong.

Because she can fly up, the children have not yet learned to fly, and the body is very thin and weak.

The mother mallard swam around the edge of the pond and quacked in a hurry. The little mallard also swam around behind her mother.

If they can't get to the shore, these little mallard ducks may die due to lack of physical strength when they are born.

Teacher Wang Yan was ready to help them when he saw it.

If you use nets to catch them, these ducks don't know that they are helping them, and they may run away in fright and consume more energy.

So they put a ladder down on the edge of the pond.

The mother mallard took the child to hide from a distance, very vigilant, but as soon as the ladder was set up, it quickly came over for inspection.

After that, the ladder was remodeled and put on plywood and felt cloth to make the ladder more "duck-like". After two hours, when the sun was about to set, a little duck finally took the first place bravely. step.

After that, the brood of ducklings followed the ladder and left the pond in line. "

"Wow, so touched!"

Protecting wild animals sounds very tall, but in fact, there is no need to do earth-shattering things.

As long as they create some favorable conditions, great changes can take place, and cities can become ecologically natural.

On the sign next to it, there is a comparison chart of two different pools, and their differences and effects on animals.

Outside the pool, some tall trees are scattered, and under the trees are shrubs and tall grasses, all native plants.

The vegetation zone with varying heights can increase the abundance of insects, provide food for birds, and also provide cover for the transition from densely planted areas to open areas. It has good concealment and small animals such as raccoon dogs, civet cats, and otters. You can take a day break in the dense grass.

These trees and shrubs are excellent habitats for birds to stop and sing, build nests and breed. They are far away from buildings and close to water sources. Food and drinking water are also abundant. The deciduous layer under the arbor will not be cleaned up, and the fallen leaves will slowly rot and turn into humus to give birth to life.

In the middle of the green belt of the community, there are some landscaping walls made of hollow bricks, on which are climbing some green vines, the cavity of the wall can also be used as a nest for bats and birds.

Between the green space and the road, there are no stone teeth, so that the little beast will not be hindered when migrating across the road.

There is a Benjas pile in the corner, which is a pile of stones and wood, filled with soil mixed with native plant seeds, and planted some thorny, sprawling protective plants. This structure has many gaps and is natural for small animals. Sanctuary.

Fang Ye walks and introduces!

The green belts of the community are all arranged in this way.

Such an environment does attract many small animals, and birds can be heard singing and singing along the way, flying between the bushes and leaves.

Walking forward, here is a small square for tourists to rest, with benches and trash cans.

What is striking is that there are also some cat statues with different poses here.

Some clumped together, lying on the edge of the flower bed, lazily basking in the sun, and some stood on tiptoe, paws on the edge of the trash can, seeming to want to see if there is food in it, and some protruded from the bushes. Head, look around.

A netizen asked curiously: "Is this the theme of stray cats?"

Fang Ye said: "That's right! When it comes to urban animals, we have to mention stray cats.

Some people say that cats eat mice. In fact, cats are opportunistic predators. Rats, rabbits, birds and frogs, as long as they are of the right size, can eat them. They don't specifically stare at mice.

Some researchers have specifically counted the diets of stray cats. Birds account for about 20%-30%. Cats in different regions have different diets, but they will undoubtedly prey on birds.

No matter what rare bird is, it is a piece of meat in the eyes of a cat, not as safe and harmless as many people think. "

Some people say that other animals also eat birds?

However, domestic cats are domesticated and hybridized from wild cats of different genera. They are pets that serve humans and have been separated from the category of nature.

When they return to nature, their identity is not a wild animal, but an invasive species, the same as scavengers and Brazilian tortoises.

Wild animal eating birds will not affect the natural balance, stray cats will, and the effect is very large. "
