About These Birds
Bare-legged Owl
The Bare-legged Owl is a small owl of the family Strigidae endemic to Cuba, inhabiting forests and woodland across the island. Weighing about 95.5g with a wingspan of 28.8cm, it is characterized by its unfeathered tarsi, which distinguish it from other Cuban owls. It is nocturnal, hunting insects, lizards, and small vertebrates in forested 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.
