About These Birds
Baja Pygmy-owl
The Baja Pygmy-owl is a small owl endemic to the mountains of Baja California Sur, Mexico, weighing about 57.5g with a wingspan of 17.7cm. Like other pygmy-owls it is often active during daylight hours and hunts small birds, lizards, and insects. Its restricted mountain range makes it sensitive to habitat disturbance.
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.
