About These Birds

Little Owl

纵纹腹小鸮（约180克）是一种分布于欧洲、亚洲和北非的小型猫头鹰。具有扁平头部、白色眉纹和凶猛表情。栖息于开阔农田、果园和村庄附近，白天和夜间均可见其活动。以昆虫、蚯蚓和小型脊椎动物为食。无危；能很好地适应人类改造的景观。

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.
