About These Birds
Mottled Owl
반점올빼미(Ciccaba virgata)는 멕시코부터 아르헨티나에 이르는 광범위한 지역에 서식하는 올빼미입니다. 갈색과 흰색의 복잡한 무늬 깃털을 가지며, 열대 및 아열대 삼림에서 야행성 생활을 합니다.
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.
