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.
Great Horned Owl
The great horned owl is the most powerful and widespread owl in the Americas, earning the nickname tiger of the sky. It is one of the earliest nesting birds, often laying eggs in January when snow still covers the ground. Great horned owls are fierce predators, regularly taking prey up to three times their own weight.
