HAWK OWL
Surnia ulula
DESCRIPTION
The Hawk Owl, or Surnia ulula, is a medium-sized owl characterized by its striking appearance, featuring a round head, large yellow eyes, and a distinctive facial disc. Its plumage is mottled brown and white, providing excellent camouflage against the bark of trees. This species is known for its unique hunting behavior, often perching on high branches to scan the ground for prey, and it is active during the day, which is unusual for owls.
