About These Birds
Black-and-white Owl
검은줄무늬올빼미(Ciccaba nigrolineata)는 멕시코 남부부터 남아메리카 북부에 걸쳐 서식하는 중형 올빼미입니다. 흰색 바탕에 검은 줄무늬 깃털이 특징이며, 열대 우림에서 서식합니다. 야행성으로 설치류와 작은 새를 잡아먹습니다.
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.
