乐生活The Polish national bird, Haliaeetus albicilla, is a very large raptor in the Eagle family. Mainly distributed in Europe, northern Asia, China and Japan to India, Greenland. The image of the white-tailed sea sculpture can be seen in the Polish national emblem.
They eat a wide range of diets, mainly fish, birds and small and medium-sized mammals, and sometimes carrion and animal carcasses. Poultry and livestock are occasionally attacked when food is scarce in winter. As a powerful hunter, some white-tailed Eagles even compete with gold Eagles for rabbits. The requirement of food is different in different periods. There is more requirement during reproduction period, but it will decrease a lot in winter. Its ability to endure hunger is also strong among raptors, which can not eat for more than 45 consecutive days.
Usually nests are built on tall trees near lakes, rivers or rivers. Usually a nest can be used for many years without disturbance. It has been used in Europe for more than 20 years. Of course, it needs to be repaired every year. Therefore, the diameter of the newly built nest is usually less than 1 meter. With the increase of service life, the structure of the nest is becoming larger and larger, with a diameter of more than 2 meters.
However, due to the increase of human pressures such as environmental pollution, habitat loss and indiscriminate hunting, the number of population in most areas of its distribution has been significantly reduced.
