About These Birds

Bermuda Saw-whet Owl

버뮤다올빼미는 17세기에 멸종한 버뮤다 고유의 작은 올빼미였다. 고양이, 쥐, 돼지와 같은 유럽 정착민이 들여온 외래 포유류가 도입되면서 멸종한 것으로 추정된다.

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.
