About These Birds
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.
Emperor Penguin
황제펭귄은 모든 펭귄 중 가장 크고 무거운 종이다. 남극 겨울에 번식하며 영하 60도의 혹독한 추위를 견딘다. 수컷이 두 달 이상 알을 품는 동안 먹이 없이 버티는 것으로 유명하다.
