Habitat Comparison
African Penguin
Rocky coastlines and offshore islands of southern Africa. Nests in burrows, under boulders, or in surface scrapes.

Great Horned Owl
Deep, resonant 'who-who-who-who-ooo': the classic 'hoo-h'HOO-hoo-hoo' territorial duet of a mated pair. Booms at dusk. Female pitch slightly higher than male.
Geographic Range & Migration
African Penguin
Coastal southwestern Africa from Namibia to Port Elizabeth, South Africa. The only penguin species breeding in Africa.

Sturdy, pointed, black bill with a grey band near the tip
Great Horned Owl
Mottled grey-brown plumage with heavy dark barring. Prominent ear tufts, yellow eyes, and a white throat patch give a fierce expression.
Dark grey-black hooked bill almost hidden by facial disc feathers
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.
