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.
Superb Fairywren
The superb fairywren is one of Australia's most beloved and recognizable birds, with breeding males dressed in spectacular violet-blue plumage. These tiny birds live in cooperative family groups where helpers assist the breeding pair in raising young. Males pluck and present yellow flower petals to females as part of courtship.
