About These Birds
Peregrine Falcon
The peregrine falcon is the fastest animal on Earth, reaching speeds over 389 km/h during its characteristic hunting stoop. Like the bald eagle, peregrines suffered dramatic declines from DDT but have recovered through intensive conservation programs. They have adapted remarkably well to urban environments.
白尾海雕
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.
