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.
Black-capped Screech-owl
The Black-capped Screech-owl is a small, nocturnal owl of Atlantic Forest in southeastern South America, with distinctive ear tufts, a black-bordered facial disc, and cryptic brown-streaked plumage. It inhabits the forest understory and edges of humid forests in Brazil, Argentina, and Paraguay. It feeds on large insects, small mammals, and other small vertebrates at night.
