About These Birds
Black-capped Screech-owl
The Black-capped Screech-owl is a small, nocturnal owl of Atlantic Forest in southeastern South America, with distinctive ear tufts, a black-bordered facial disc, and cryptic brown-streaked plumage. It inhabits the forest understory and edges of humid forests in Brazil, Argentina, and Paraguay. It feeds on large insects, small mammals, and other small vertebrates at night.
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.
