About These Birds
Austral Pygmy-owl
The Austral Pygmy-owl is a small, diurnal owl found in the temperate forests and shrublands of Chile and Argentina. Weighing about 75g with a wingspan of 19cm, it is the southernmost owl in the world and is active during daylight hours. It hunts small birds, insects, and lizards from concealed perches in the forest.
Virginia-Uhu
Der Virginia-Uhu ist die kraftvollste und am weitesten verbreitete Eule Amerikas und trägt daher den Beinamen Tiger des Himmels. Er zählt zu den frühesten Brutvögeln und legt seine Eier oft schon im Januar, wenn noch Schnee liegt. Der Virginia-Uhu ist ein gefürchteter Jäger, der regelmäßig Beute erlegt, die bis zu dreimal so schwer ist wie er selbst.
