Size Comparison
Habitat Comparison
Emperor Penguin
Antarctic pack ice and surrounding Southern Ocean. The only penguin species that breeds during the Antarctic winter.
Snowy Owl
Arctic tundra for breeding. Winters in open habitats resembling tundra, including prairies, airports, shorelines, and agricultural fields.
Song & Call Comparison
Emperor Penguin
Loud, resonant trumpeting calls used for individual recognition in dense colonies. Each bird's call is unique in frequency. Also gives softer contact 'braying' notes.
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
Emperor Penguin
Antarctic continent and surrounding sea ice. Breeding colonies are found along the entire Antarctic coastline.
Snowy Owl
Circumpolar Arctic for breeding. Irruptive winter movements bring birds south to the northern United States, Europe, and Asia.

About These Birds
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.
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.
