About These Birds
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.
オジロワシ
The white-tailed eagle is Europe's largest eagle and the fourth-largest eagle in the world. Once extinct in Britain, it has been successfully reintroduced to Scotland and Ireland through conservation programs. These powerful raptors can live over 25 years and form lifelong pair bonds.
