Range: Coastal regions of northwestern China and Siberia, along Kamchalia peninsula and the Japanese islands
Habitat: Along coastal and forested river valleys where fish are plentiful
Lifespan: Variable, not much data available, but a mature eagle may live more than 20 years
Wild Diet: Principally fish, but will take ducks and other small mammals
Zoo Diet: Fish, rabbit, horse meat
Spends most of its day perched until prey is spotted. Handles seasonal changes with behavior alteration.
Builds large nests of sticks in tall trees which it uses for up to 10 years. Mating is done in March by "calling" each other over the breeding area. Mating often takes place on the nest. After the female lays the eggs, both sexes feed the chicks.
Gestation: Roughly a 40-day egg incubation period and then 70 days to chick fledgling
Litter: Clutch size: 1 to 3 eggs
Conservation Status: Vulnerable
The total population of theses eagles was most recently estimated at 7,500 birds - they are considered rare. The remoteness of their habitat keeps them somewhat protected from humans.
