About These 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.
Barred Owl
The Barred Owl is a large owl of the family Strigidae found in mature forests, swamps, and mixed woodlands across much of North America. Weighing about 760g with a wingspan of 68.2cm, it is named for its distinctive horizontal barring on the breast. It is nocturnal and calls with a resonant 'who cooks for you' hooting, hunting small mammals, birds, and amphibians.
