About These Birds
Abyssinian Owl
The Abyssinian Owl is a medium-sized owl weighing around 323g with a 67cm wingspan, found in East African highlands. It hunts small mammals and birds in montane forest and moorland habitats.
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.
