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.
Bearded Screech-owl
The Bearded Screech-owl is a small owl found in the highland cloud forests of the Sierra Madre de Chiapas in Mexico and western Guatemala. It has brownish, cryptically patterned plumage with fine barring and elongated ear tufts. Like other screech-owls, it hunts small invertebrates and vertebrates at night in dense montane forest.
