About These Birds
Barking Owl
The Barking Owl is a medium-to-large owl of the family Strigidae found in woodland and open forest across Australia and parts of New Guinea. Weighing about 567.3g with a wingspan of 59.7cm, it is named for its distinctive dog-like barking call. It is nocturnal, hunting rabbits, possums, small birds, and large insects from exposed perches.
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.
