About These Birds
Andean Pygmy-owl
The Andean Pygmy-owl is a tiny nocturnal hunter with a 19.9 cm wingspan, weighing around 66 grams. It inhabits montane forests and forest edges along the Andes. Despite its small size, it preys on small birds, mammals, and insects, often hunting during daylight hours.
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.
