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.
Schnee-Eule
Die Schnee-Eule ist die schwerste Eule Nordamerikas und einer der charismatischsten Vögel der Arktis. Anders als die meisten Eulen ist sie größtenteils tagaktiv – bedingt durch das durchgehende Tageslicht der arktischen Sommer. Periodische Masseneinflüge der Schnee-Eule nach Süden hängen mit den Populationszyklen der Lemminge zusammen.
