About These Birds
European Roller
因求偶时的翻滚飞行而得名。欧洲唯一的佛法僧科鸟类。种群数量下降。
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.
