About These Birds
Short-eared Owl
短耳鸮是一种中型猫头鹰（约350克），广布于除澳大拉西亚外的所有大洲。常见于白天在开阔的草地、沼泽和苔原上空低飞觅食。耳羽极短，面盘呈圆形，具黄色眼睛。无危；种群数量受猎物（主要是田鼠）数量影响，会周期性波动。
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.
