Size Comparison
Habitat Comparison
Barn Swallow
Open farmland, meadows, and areas near water. Nests almost exclusively in human-made structures such as barns, bridges, and eaves.
Snowy Owl
Arctic tundra for breeding. Winters in open habitats resembling tundra, including prairies, airports, shorelines, and agricultural fields.
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.
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
Barn Swallow
Breeds across the Northern Hemisphere in North America, Europe, and Asia. Winters in South America, Africa, and South Asia.
Snowy Owl
Circumpolar Arctic for breeding. Irruptive winter movements bring birds south to the northern United States, Europe, and Asia.

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.
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.
