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.
Roseate Spoonbill
The roseate spoonbill is the only spoonbill species in the Americas and one of the most striking wading birds in the Western Hemisphere. Like flamingos, their pink color comes from carotenoid pigments in their crustacean prey. Nearly hunted to extinction for their plumes in the 19th century, they have recovered substantially.
