Growth and reproduction
Nest in the tall jungle trees or forest edge, nest height from the ground about 10-25 meters. Branches to build nests, lined with fur Toba, cloth and other items. With the capture of different environments and species have changed, sometimes as low as 2 meters and 25 meters above high. Discoid shape of the nest, constituted mainly by the dry branches, twigs inside the pad, fur, hay and grass stems. If reproductive success, nest to be continued the following year was also used, usually a nest can be used for many years, but every year the need for repair and add new nesting material, so as the use of life increases, the nest becomes much larger. April-May spawning, spawning two per litter, litter two eggs, egg white, with brown spots. Output after the first one began to hatch the eggs, male and female co-incubation of about a half months. Brooding period, females remain in the nest, the male hunting to feed, when fed up to 5-6 times the number a long time, as of late chicks were white feathers, hatched about 43 days, 55 days later nest. Purdue University scientists bird feathers for dna analysis found, the Imperial Eagle in Central Asia may be the world's most faithful of birds. The researchers analyzed the feathers remain in the nest after dna, a natural habitat in Kazakhstan found that a single tribe of white imperial eagle. Analysis shows that no one adult eagle with their spouses separated, this high degree of loyalty is very rare in birds because the vast majority of bird species have multiple spouses and children. White imperial eagle of observational studies show that the largest birds of prey are monogamous animals, males and females that will be together throughout the feeding period, shared parenting responsibility to future generations.

Population Status
Global Vulnerable (collar et al., 1994). Unusual migratory birds, populations continued to decline and has been endangered. Named subspecies breeding in northwest Xinjiang Tianshan region. Sometimes, when seen in the northeast coastal migration provinces of Qinghai Lake in the winter around the northwest of Yunnan, Gansu, Shaanxi, Fujian and Guangdong and the Yangtze River. A small amount each year to Hong Kong. See "up to Ben Lake Nature Reserve." Children recently discovered in China around the Imperial Eagle of the records, records in the last three years a total of six sites found 11 times. One 1994 survey, the white imperial eagle in the east of Shenzhen Bay, has seven mountain twin carp. 2005 Xingkaihu migratory briefing records, found that white imperial eagle 2.
