About These Birds
Black-banded Owl
黑带林鸮(Ciccaba huhula)是一种中型猫头鹰，栖息于南美洲的热带雨林，以其深棕色羽毛上的浓密黑色条纹为特征。分布于整个亚马逊盆地，在密林中捕食小型哺乳动物、蜥蜴和大型昆虫。
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.
