About These Birds
Baja Pygmy-owl
The Baja Pygmy-owl is a small owl endemic to the mountains of Baja California Sur, Mexico, weighing about 57.5g with a wingspan of 17.7cm. Like other pygmy-owls it is often active during daylight hours and hunts small birds, lizards, and insects. Its restricted mountain range makes it sensitive to habitat disturbance.
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.
