About These Birds
Band-bellied Owl
The Band-bellied Owl is a medium-sized owl of the family Strigidae found in Andean foothill forests from Peru to Bolivia. Weighing about 82g with a wingspan of 55.2cm, it has distinctive dark brown banding across the belly. It hunts small vertebrates and large insects in humid montane forest at night.
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.
