About These Birds
American Crow
미국까마귀는 북미에서 가장 친숙하고 지능이 높은 새 중 하나이다. 연구에 따르면 도구를 사용하고, 인간 얼굴을 기억하며, 복잡한 사회 구조를 이룬다. 북미 전역의 다양한 서식지에 적응력이 뛰어나게 서식한다.
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.
