About These Birds
イヌワシ
The golden eagle is one of the most powerful and agile raptors in the Northern Hemisphere. Revered by many cultures, it has been used in falconry for centuries, particularly by Kazakh eagle hunters of Central Asia. Golden eagles can dive at speeds exceeding 240 km/h when pursuing prey.
Great Blue Heron
The great blue heron is the largest heron in North America, standing up to 1.4 meters tall. These patient hunters can stand motionless for extended periods before striking at prey with remarkable speed. They nest in large colonies called heronries, often returning to the same site year after year.
