About These Birds
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.
Annobon Scops-owl
The Annobon Scops-owl is a critically endangered small owl endemic to Annobón Island, with a wingspan of about 26 cm and weighing around 67 grams. As one of the rarest owls in Africa, it faces severe threats from its extremely restricted island range. Its nocturnal habits and small population make conservation efforts especially urgent.
