About These Birds
Albertine Owlet
The Albertine Owlet is a small, near-threatened owl weighing about 73 g with a wingspan of 26 cm. Endemic to the montane forests of the Albertine Rift in Central Africa, it is rarely observed and its habits are poorly known due to its remote and dense forest habitat.
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.
