About These Birds
부채머리독수리
하피수리는 세계에서 가장 강력한 맹금 중 하나로 발톱이 회색곰의 발톱만큼 크다. 멕시코에서 볼리비아와 브라질까지 아메리카 열대우림에 서식하며 나무늘보, 원숭이, 이구아나 등을 사냥한다.
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.
