About These Birds
Mandarin Duck
オシドリ。東アジア原産の美しいカモ。雄は鮮やかなオレンジ色の「帆羽」と複雑な羽毛模様が特徴的。体長41〜49cm。森林の池や川に生息し、樹洞に巣を作る。ドングリや水草を食べる。低危険種。
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.
