About These Birds
Barred Eagle-owl
The Barred Eagle-owl is a Near Threatened large owl of the family Strigidae found in primary and tall secondary forests of Southeast Asia, including Sumatra, Borneo, and the Malay Peninsula. Weighing about 1,113g with a wingspan of 66.4cm, it has distinctive horizontal barring and prominent ear tufts. It hunts at night, taking large insects, small mammals, and birds.
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.
