Extended data:
Historically, hunting with eagles was called eagle hunting. Sima Qian recorded in Historical Records that Li Si, the prime minister of Qin Dynasty, was still thinking about the life of "leading a yellow dog with an eagle on his arm and going out to the East Gate of Shangcai" before he was executed. It can be seen that falcon was one of the main recreational activities of the nobles at that time. There are many kinds of eagles used in eagle hunting. In China, goshawk is the main species. This kind of eagle is slender, with a body length of 0.5 meters, and the female eagle is larger than the eagle, about 0.56 meters.
According to textual research, Falcon originated in the East, starting from 72 1 ~ 705 BC when King Sargon II of Assyria (the kingdom of northern Mesopotamia, now northern Iraq) was in power. Later, western businessmen, adventurers and crusaders learned eagle hunting in the East and introduced it to the European continent. At first, falcons were the exclusive pastime of the privileged. In the17th century, falcons became popular among the public. 1770, the world's first falconer association was established in Britain.

Hawks generally move at night, mostly inhabiting mountains and plains. Eagle's eyes are particularly keen. It is difficult for human eyes to see bugs 20 meters away, but it is very easy for eagles. Eagles can even see bugs 100 meters away. Because there are many' cone cells' on the retina of the eagle eye, its vision is eight times sharper than that of human beings.
Hawks refer to different creatures in different contexts, usually small to medium-sized hawk-shaped daytime birds. Compared with eagles, falcons, owls and other raptors, they refer to the subfamily Eagle. In the Animal Atlas of China, it refers to the subspecies of the black-eared kite, which belongs to Araliae.

Different blackbirds have different shapes. The smallest blackbird is only about 6 cm, while the largest blackbird is only about 30 cm. From the data point of view, the smallest white-legged falcon in eagles is close to 20 cm, and most other eagles are more than 50 cm long.
Cockroaches' small bodies are more flexible, and their beaks are very sharp, which can easily peck off the fur of most animals, which makes the eagle very headache. The eagle is too big. Its flight in the mountains is limited by many things, but cockroaches are different. It can freely shuttle through the dense forest, usually by flying directly to the head of its prey and pecking its skull with its sharp beak.
