There is a saying in our country that "swallows do not enter the door of bitter cold." This is because people have observed that swallows often build nests under the eaves of high-ranking households and do not favor the thatched houses of poor people. In fact, the reason is not difficult to understand. Swallows’ nests are mainly built of mud and sand, and they are not very stable. The above is for shelter from the wind and rain. The more noble a mansion, the larger the eaves, the more wind and rain it can block, and the more comfortable life is.
Recently, however, scientists have discovered that it is not only swallows, but "to be poor and love rich" is a common problem among birds all over the world.
Scientists have studied the distribution of birds in 22 urban areas in South Africa. South Africa is a country rich in species and the gap between rich and poor, so it is very suitable for studying the relationship between the distribution of birds and the gap between rich and poor.
South Africa has 10% of the terrestrial plants and 7% of the animal species in the world. There are nearly a thousand species of birds that have been recorded, of which about 50 species are unique to South Africa. Penguins can also be seen in South Africa! The difference between rich and poor is particularly vivid in the cities of South Africa: villas in the rich areas are surrounded by lush foliage and picturesque scenery, and the other side is separated by 200-meter-wide wetlands, electric fences and guardhouses. On the other hand, it is the poor shack of Mi Mizaza, and the stinky drains, garbage collection stations and industrial areas that pollute the environment are all on this side.
In this survey in South Africa, the scientists found that the number of living species of bird in the affluent district far more than the ghetto, that the more affluent residents, the more the birds found there, this phenomenon is called "luxury effect
In fact, this This is not the first time this phenomenon has been discovered. American scientists have previously studied the distribution of birds in Phoenix, the capital city of Arizona. They investigated 15 community parks located in different communities, rich and poor, and also found areas for the rich. There are far more types of birds in the park than in the poor areas. However, because of the small number of samples, they did not thoroughly study the reasons for this phenomenon. The results of this study on the distribution of birds in South Africa show that birds Children’s "dislike the poor and love the rich" is not an isolated phenomenon, the birds all over the world are like this.
Comparing the environment of the rich area and the slum area, it is not difficult to derive the reason why the birds "like the poor and love the rich". The rich areas have more gardens, parks and other green spaces, and there are fewer industrial areas, and the water and air are cleaner. These are the reasons why the rich communities are more attractive to birds.
We study where birds prefer to live in order to build homes that are more suitable for humans to live in. Humans need a home where birds and flowers are scented, and they must build a natural and harmonious environment that can attract birds. To create such an environment, it is necessary to reasonably allocate the ratio of housing and green space to ensure people's living space while maintaining more green space to attract more birds to live with us. In such an environment, Human life will be happier.
