Kids' Inquiry of Diverse Species

Local animals in this group:

owls

Strigiformes

There are almost 200 different species of owls around the world. These nocturnal carnivores (night-time hunters) have large eyes that face forward, for seeing in three dimensions in dim light. They also have disk-shaped faces that help focus the slightest sounds their small prey might make in the dark. Their soft feathers allow them to fly almost silently. Owls have strong feet with toes in an unusual arrangement: two toes point forward and two point backwards.
