About These Birds

Short-eared Owl

北極圏から亜熱帯まで世界中に分布するフクロウ(体長34〜43cm)。短い耳羽と黄色い目が特徴。Asio flammeus(コミミズク)は草原、湿地、ツンドラに生息し、日中でも狩りをすることがある。特にコレクション・ゲームとして知られる「蜂起型」飛行で草地のマウスを捕食する。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.
