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.
Downy Woodpecker
솜털딱따구리는 북아메리카에서 가장 작고 가장 널리 분포하는 딱따구리이다. 소형 체구 덕분에 더 큰 딱따구리가 접근할 수 없는 가는 나뭇가지와 잡초 줄기에서 먹이를 찾을 수 있다. 솜털딱따구리는 겨울에 혼종 무리에 합류하여 여러 종이 함께 포식자를 감시하는 이점을 얻는다.
