About These Birds
Amazonian Pygmy-owl
The Amazonian Pygmy-owl is a tiny owl weighing about 56 g with a 17.9 cm wingspan, active during daylight hours in Amazonian forest. Despite its small size, it is an aggressive predator of small birds, lizards, and large insects.
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.
