Like hawks and eagles, owls of New York are birds of prey. They are most noticable because of their large eyes. They cannot move rotate their eyes within the socket, so they must move their head when looking about. Because they have forward facing eyes, they have well developed binocular vision giving them great depth perception.
Owls' ears are located on the facial disc behind the eyes and are concealed by feathers. The tufts of feathers atop some owl's heads, referred to as 'ear tufts' are for display only. Their hearing is very sharp, enabling them to pinpoint the slightest noises made by potential prey.
Owls have developed special feathers that enable them to minimize sound when flapping their wings. The forward edges of their primary feathers have a stiff fringes that reduces noise while the trailing edges have soft fringes to reduce turbulence. Their wing surfaces are covered in downy feathers to further reduce sound.
Owls are primarily nocturnal hunters and hunt alone. They perch in trees with a good view of their surrounding area waiting for small animals and rodents such as mice, squirrels, voles and rabbits. Owls cannot chew their prey since, like all birds, they do not have teeth. Instead, they swallow small prey whole or tear larger prey into smaller pieces with their sharp hooked beak before swallowing.
Owls do not make their own nests. Instead they use nests abandoned nests made by other large birds or in the hollow trunks of trees.
