About These Birds
Burrowing Owl
北米・南米の草原、砂漠、農地に生息するフクロウ（体長19〜25cm）。地面のウサギ塚や自分で掘った穴に住む珍しいフクロウ。Athene cunicularia（アナホリフクロウ）は長い脚を持ち、昼間でも活動的。プレーリードッグやジリスなどの哺乳類が掘った穴を利用して繁殖する。Strigidae科。
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.
