About These Birds
Bearded Screech-owl
The Bearded Screech-owl is a small owl found in the highland cloud forests of the Sierra Madre de Chiapas in Mexico and western Guatemala. It has brownish, cryptically patterned plumage with fine barring and elongated ear tufts. Like other screech-owls, it hunts small invertebrates and vertebrates at night in dense montane forest.
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.
