About These Birds
Northern Fulmar
The northern fulmar is a long-lived seabird that can survive over 40 years. It defends its nest by projectile-vomiting a foul-smelling stomach oil at intruders, which can mat the feathers of predators and cause fatal loss of waterproofing. Fulmars have expanded their breeding range dramatically southward over the past two centuries.
อินทรีหางขาว
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.
