About These Birds
Albertine Owlet
The Albertine Owlet is a small, near-threatened owl weighing about 73 g with a wingspan of 26 cm. Endemic to the montane forests of the Albertine Rift in Central Africa, it is rarely observed and its habits are poorly known due to its remote and dense forest habitat.
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.
