Size Comparison
Habitat Comparison
Downy Woodpecker
Deciduous and mixed forests, orchards, parks, and suburban areas. The most common woodpecker at feeders in North America.
Snowy Owl
Arctic tundra for breeding. Winters in open habitats resembling tundra, including prairies, airports, shorelines, and agricultural fields.
Song & Call Comparison
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'.
Snowy Owl
Male gives a deep booming hoot 'hooooo' and a rising 'hoo-hoo' series. Also barks sharply when alarmed. Quieter than many owls; silent during long Arctic winter hunts.
Geographic Range & Migration
Downy Woodpecker
North America from Alaska and Canada south through the United States, excluding the arid Southwest.
Snowy Owl
Circumpolar Arctic for breeding. Irruptive winter movements bring birds south to the northern United States, Europe, and Asia.

Snowy Owl
Adult males are almost entirely white. Females and immatures have dark brown barring and spotting. Yellow eyes and fully feathered feet.
Dark hooked bill mostly hidden by dense facial feathering
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.
Snowy Owl
The snowy owl is the heaviest North American owl and one of the most charismatic Arctic birds. Unlike most owls, it is largely diurnal, necessitated by the continuous daylight of Arctic summers. Snowy owl irruptions — periodic mass southward movements — are tied to lemming population cycles.
