What is the function of a bird of prey's tail, and what are the common species of eagles?

The eagle is a bird with an extremely wide distribution; this is only a general term, because it has many different classifications. The eagle's eyes are very sharp, able to see things clearly from far away, and when hunting it is fast, accurate and ruthless, which is also because it has already fixed its eyes on the target. The eagle is a carnivorous group, very fierce by nature, and in China it is relatively common mainly in Tibet, Qinghai, Inner Mongolia and other places. So what is the function of the bird of prey's eagle tail? What are the relatively common species?

1. What is the function of a bird of prey's eagle tail?

When an eagle flies in the sky, we see its tail sometimes spread out and sometimes contracted; in fact, both serve to assist the body in moving forward in different postures, maintain the body's balance, and control the direction of travel. For example, when it needs to turn during flight, it must slow down and control its balance, so it spreads its tail. If it spots prey on the ground, it must fold its tail and dive downward at speed.

1. Northern Goshawk

The Northern Goshawk is also called the chicken hawk or yellow hawk. The male hawk is a large-bodied bird with a grayish-black head and a white underside mixed with spots. The female hawk is slightly smaller, with grayish-brown wings and upperparts. When the Northern Goshawk flies, its tail is relatively long, and it can fly in a straight line, with a flight speed somewhat faster than other species of hawks.

The Northern Goshawk is mainly distributed in China's Guangdong, Yunnan, Northeast China and other regions, inhabiting forest areas such as coniferous forests, mixed forests and broad-leaved forests at different altitudes, and is also seen in open woodlands and small patches of forest in mountainous plains and hilly areas. The Northern Goshawk likes to prey on small mammals, such as hares, wild mice and so on, and sometimes also eats birds.

2. Eurasian Sparrowhawk

The Eurasian Sparrowhawk is also called the sparrow hawk. It is somewhat smaller than the Northern Goshawk. The adult Eurasian Sparrowhawk has bluish-gray upperparts, and its tail feathers are relatively long with dark brown horizontal spots, making it easy to identify. When flying, the Eurasian Sparrowhawk mainly alternates between short glides to move forward. The Eurasian Sparrowhawk likes to inhabit mountain forests and likes to prey on small birds. The Eurasian Sparrowhawk can serve as a domesticated falcon. The Eurasian Sparrowhawk is mainly distributed across Eurasia, south to northwestern Africa, and east to Iran, India, China and Japan. For wintering, it is generally found in the Mediterranean, Arabia, India, Myanmar, Thailand and Southeast Asian countries.

3. Chinese Sparrowhawk

The Chinese Sparrowhawk mainly breeds in the middle and lower reaches of the Yangtze River, in Hunan, Hubei, Anhui, Zhejiang, Guangdong and other places. It is somewhat larger than the Eurasian Sparrowhawk and likes to eat lizards, frogs, large insects, small birds and so on.

4. Argentavis

Argentavis could reach a body weight of 140 jin, and its wings spread out to a full seven meters across, looking as large as a small airplane.
