Habitat Comparison
Barn Swallow
Open farmland, meadows, and areas near water. Nests almost exclusively in human-made structures such as barns, bridges, and eaves.
Downy Woodpecker
Deciduous and mixed forests, orchards, parks, and suburban areas. The most common woodpecker at feeders in North America.
Song & Call Comparison
Barn Swallow
A rapid, twittering song: a long stream of 'vit-vit-vit' and rolling chirps. Also gives a sharp 'vit' flight call. Song can last many minutes without pause. Musical and liquid.
Downy Woodpecker
A sharp 'pik' or 'peek' contact call. Drums on resonant branches with a rapid, light tattoo — softer than larger woodpeckers. Also gives a high descending whinny 'keeer-keeer'.
Geographic Range & Migration
Barn Swallow
Breeds across the Northern Hemisphere in North America, Europe, and Asia. Winters in South America, Africa, and South Asia.
Downy Woodpecker
North America from Alaska and Canada south through the United States, excluding the arid Southwest.

About These Birds
Barn Swallow
제비는 세계에서 가장 넓게 분포하는 제비류이며, 어떤 참새목 조류보다 가장 긴 이동을 합니다. 북반구 전역에서 봄의 도래를 알리며, 고대 그리스에서 현대 시에 이르기까지 문화적 참고가 되고 있습니다. 제비는 둥지를 위해 인공 구조물에 거의 완전히 의존하게 되었습니다.
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.
