About These Birds
Black-and-white Owl
黑白林鸮(Ciccaba nigrolineata)是一种中型猫头鹰，分布于从墨西哥到秘鲁的湿润低地森林。具有引人注目的黑白斑纹图案。在茂密的雨林树冠层中捕食小型哺乳动物、青蛙和大型昆虫。
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.
