About These Birds
Bare-shanked Screech-owl
The Bare-shanked Screech-owl is a medium-sized owl of the family Strigidae found in montane forests of Costa Rica and western Panama. Weighing about 155.8g with a wingspan of 36.2cm, it is characterized by its unfeathered tarsi. It is nocturnal and hunts insects, small vertebrates, and invertebrates in highland forest 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.
