About These Birds
Black-and-white Owl
The Black-and-white Owl is a medium-sized owl of humid lowland forests from Mexico to Peru. It has striking black-and-white barred plumage with large dark eyes. It hunts large insects, small rodents, and birds at night, often near forest streams and edges.
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.
