About These Birds
Alor Boobook
The Alor Boobook is a small owl weighing about 180 g, endemic to the island of Alor in eastern Indonesia. A member of the Strigidae family, it inhabits forest and woodland on the island and hunts insects and 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.
