From flooding to genocide, how did the United States destroy 5 billion traveling pigeons?

Species flooding has always been a headache for many countries, but it took less than 100 years for the United States to eat a flooded bird until it became extinct. What's going on here? When the first European colonists landed in North America, they found a large number of birds here, and they all appeared in groups, but no one knew its name. It was not until 1766 that this bird, that is, the passenger pigeon, was officially recorded in North America. The pigeon is a medium-sized brother, with a body length of 30 to 40 cm, wings spread about 60 cm and a weight of about 260 grams. Its head and back are mainly blue-gray, and its abdomen and tail are brown-gray. It is a social species, mainly eating berries and seeds and some invertebrates. Before the appearance of human beings, traveling pigeons lived a carefree life in this land of North America, forming a huge group, the number of which reached 5 1. When they fly in the air together, they form a spectacular scene covering the sky.

In order to catch the traveling pigeons faster, they also developed a huge bird net. As long as the pigeon strays into the bird net, it can only be caught easily. At that time, the colonists' labor force was servants and slaves. These cheap pigeons were their food and were also made into feed for various animal husbandry. Travelling pigeons have become very sought-after prey, and they even set up special hunting teams to catch them. A hunting party can catch hundreds of thousands or even millions of monitor lizards. At that time, there were 50 thousand trips every day, and the captured pigeons were knocked down by a truck and pulled into the net. Due to too many catches in North America, it will cause unsalable sales. But because of the low cost of hunting, hunters are not distressed. They dumped the unsalable pigeon carcasses into the garbage dump, and the rotten smell could be smelled several kilometers away.

Such a large-scale killing led to a sharp drop in the number of tourists, and people of insight began to worry about Lu Ge's living conditions. They thought this species would face extinction, but the government at that time thought it was alarmist news. After all, there were still many tourists at that time, so it rejected the people's application on this ground. At the request of tourists, the government quickly broke out in the American Civil War, during which food was scarce and people began to replenish a large number of passenger pigeons. The number of passenger pigeons, which has been greatly reduced, has been hit hard again. People have also noticed the change in the number of traveling pigeons, but they are all busy fighting, and no one cares about the survival of a flock of birds.

When the war ended, scientists finally realized that pigeons were going to be extinct and began to artificially breed pigeons in an attempt to save the species, but it was of no help at this time. 19 14, the last passenger pigeon was declared dead, and the passenger pigeon completely disappeared in North America. It is the endless demand of human beings that causes the tragic fate of passenger pigeons, and the original large number of birds have been eaten and extinct under the constant hunting of human beings.
