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.
House Sparrow
집참새는 아마도 세계에서 인간과 함께 가장 성공적인 새일 것이다. 처음에는 중동에서 기원했지만 인간의 교역로와 정착지를 따라 전 세계로 퍼졌다. 씨앗, 곤충, 음식물 쓰레기를 먹는 기회주의적 잡식성이다.
