The 10 billion “African sparrows” are overwhelming, besieging elephants, sweeping farms, and shelling is ineffective

Photographers in Kenya, Africa, found a magical scene: elephants were surrounded by large groups of red billed quiliators. As we all know, the elephant is the largest mammal on the land. Even predators like lions and tigers can’t hunt it. But the red billed quiliath dares to attack it. What’s the reason?

The reason why the red billed quelia sparrow attacks the elephant is that in the dry season, the decrease of rainfall makes the fresh water resources scarce, and the small puddle nearby becomes very precious. When the red billed quelyfinch was drinking, it found that the elephant also came here to drink, so groups of red billed quelyfinches wanted to drive the elephant out. It’s amazing that elephants are not rivals of the red billed quiliards. They are very small in front of thousands of them, as if they are at the top of the food chain in Africa.

In Africa, there are 10 billion red billed quiliards, the largest number of birds in the world.

The pups of the red billed quelyfinch mainly feed on insects, while the adult ones mainly feed on grass seeds and crops. They often breed on a large scale during the autumn harvest

The famous harmful birds in agriculture and forestry. When the red billed quiliator feeds, the birds behind, in order to get food, fly to the front to eat. At this time, the birds in front become the birds behind, and rush forward to eat. The birds roll forward like wheels, and everywhere they go, the seeds are not spared.

Although the red billed quilia finch is very hateful, it is very cute, with black spots on its back, orange yellow feathers on its head and abdomen, and a small piece of black on its face. Its mouth is mostly bright red, very eye-catching, and its legs and feet are pink or orange. When breeding, the male will use grass roots or palm leaves to make a 60 cm round nest to win the favor of the female. He will also decorate some grass and feathers from time to time. After laying eggs, he will build a fence to prevent the child from falling down. This is probably a simple and simple love, first building a house, then falling in love, and finally laying eggs.

The reason for the large number of the red billed quilia

After hatching, the chicks can fly two weeks after their parents take good care of them. After a year of sexual maturity, they also begin to breed. Therefore, the number of red billed quiliath birds can reach one million in a short time. It is understood that a red billed quilia finch consumes 18 grams of grain per day, while 2 million red billed quilia finches consume about 50 tons of grain. It is conceivable that 10 billion red billed quilia finches will have a negative impact on local agriculture.

Clive Elliott said: “the main characteristic of the red billed quiliator is that it has a very large population. The retired expert has spent most of his 31 year career at the food and Agriculture Organization of the United Nations (FAO) helping farmers and governments in Africa deal with the pest. “The population of the red billed quiliator is very strong,” Elliott said. Millions of birds are killed every year, but “reducing the number” is still a big problem. They are highly mobile, have few natural enemies, and breed very fast. People have used large-scale weapons, but they still can’t completely eliminate them. The new population will quickly occupy the cleared area. They breed three times a year, and each red billed quillark lays three eggs on average. Soon, the large population of red billed quillarks will return.

The harm of the red billed quilia Finch

These birds are long-distance immigrants. They are distributed in the semi-arid, jungle, grassland and savanna areas of Africa, covering an area of more than 10 million square kilometers. “It’s a pest in many different African countries, stretching from South Africa to the north, through Tanzania, Kenya and Ethiopia, all the way through the Sahel to Mauritania,” Elliot said. In recent years, the number of red billed quilia finch has increased significantly with the increase of local agricultural production.

It is estimated that the population of the red billed quiliator has increased 10 to 100 times since the 1970s. Since the beginning of 2009, African relief agencies have reported the activities of the red billed quilia finch in Kenya in January, Zimbabwe in April, Malawi and Tanzania in May, Mozambique, Tanzania and Zimbabwe in June, and Tanzania in July. The red billed quilia finch has a direct threat to food security in Tanzania and other places, which will greatly reduce local food production. According to the daily news, the large-scale red billed quilia finch population has posed a huge threat to the production of 2135 hectares of crops, and the impact is increasing.

Management methods of the red billed quilia Finch

The most common method of prevention and control is to spray large-scale toxic chemicals on the affected area. Another method is to find the place where the birds are concentrated and use bombs or explosives. It is reported that South Africa carries out about 170 control operations every year, killing an average of 50 million. However, Clive Elliott said that “although millions of red billed quillias are destroyed every year, the damage is still increasing every year.” The large-scale use of chemicals and gunpowder will bring serious negative effects on the environment.

Most farmers can’t use medicine, gunpowder and other methods, so they choose the traditional method of killing birds. In the months when food crops are vulnerable, people go into the fields and use catapults to make impact sound and noise to scare the birds. One person can protect a hectare of land. But the job is time-consuming and laborious, usually from dawn to dusk, and requires someone to expel the birds for a month.

At present, people in many places choose to capture and eat the red billed quilia finch. Many people use various bird catching tools to capture 20000 to 40000 birds a day. However, the number of local red billed quilia finches has not been effectively controlled. In China, the way to eliminate sparrows is to catch and eat them. It takes only one year to eliminate sparrows. However, the African people use the same method, but the effect is very little. It has to be said that the survival and reproduction ability of the red billed quilia finch is very strong.

summary

https://recordunknown.com/wp-content/uploads/2021/03/f37a613a-55b4-457c-aa07-9fb531c91215_9.jpegAlt

At present, Africa’s red billed quiliator has a population of 10 billion, which is the largest number of birds on earth.

The red billed quilia finch itself is not a harmful bird. Because it has no natural enemies and is reproducing rapidly, it has swept across Africa, threatening the local food production. Although the local people take various methods, such as spraying poison, using bombs and so on, the population of the red billed quilia finch is still growing.
