About These Birds
Short-eared Owl
El búho campestre (unos 350 g) es uno de los búhos más ampliamente distribuidos del mundo, presente en todos los continentes excepto Australia y la Antártida. A diferencia de la mayoría de los búhos, caza activamente durante el día, especialmente al amanecer y al atardecer, sobrevolando praderas y marismas a baja altura en busca de topillos y otros pequeños mamíferos. Sus 'orejas' son pequeñas y poco visibles. Las poblaciones son nómadas, siguiendo las fluctuaciones de las presas.
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.
