Size Comparison
Habitat Comparison
Common Raven
Diverse habitats from Arctic tundra to deserts, mountains, forests, and coastlines. Avoids dense urban areas but thrives near human activity.
Downy Woodpecker
Deciduous and mixed forests, orchards, parks, and suburban areas. The most common woodpecker at feeders in North America.
Song & Call Comparison
Common Raven
Highly varied: deep resonant 'kraa-kraa-kraa', hollow 'tok-tok', liquid 'klonk', and wing-whooshing. Among the most intelligent corvid callers; uses calls contextually in groups.
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
Common Raven
Holarctic distribution across North America, Europe, Asia, and North Africa. The most widely distributed corvid.
Downy Woodpecker
North America from Alaska and Canada south through the United States, excluding the arid Southwest.

How to Tell Them Apart

All black with a glossy purplish-blue iridescent sheen. Shaggy throat hackles, long wedge-shaped tail, and large robust build distinguish it from crows.
Large, powerful, curved black bill
Downy Woodpecker
Black and white plumage with a broad white stripe down the back. Black wings with white spots. Males have a small red patch on the nape.
Short, chisel-shaped, dark bill — noticeably shorter than the similar hairy woodpecker
About These Birds
Common Raven
큰까마귀는 가장 지능적인 조류 중 하나로, 도구 사용, 미래 계획, 복잡한 사회적 행동을 보인다. 전반적으로 광택 있는 검은 깃털을 가지며 북반구 전역의 다양한 서식지에 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.
