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.
Arabian Scops-owl
The Arabian Scops-owl is a small nocturnal owl from the Arabian Peninsula, weighing about 66.5 grams with a wingspan near 25 cm. It inhabits rocky wadis, date palm groves, and dry woodland, where it hunts insects and small vertebrates at night. Its cryptic streaked plumage makes it nearly invisible when roosting against tree bark or rocky surfaces during the day.
