Behavior
They like to hunt at night.They have great night vision.Owls can see far away so they can chase down their preyKeen hearing so they can hear predators.Both parents feed and take care of owlets for a few weeks.
BabiesThey lay 1-5 eggs a year.Babies are called owlets.The owlets stay with their mom and dad for the first few weeks.The owlets will hatch in a few weeks.They start off only 3 to 4 inches in size
Physical Adaptation
The owls in the snowy areas are white and the owls in wooded areas are brown and tan which looks like bark of a tree so it can camouflage with the bark and snow. This helps them blend with their surroundings at rest .Powerful talons are used to grab prey.Powerful beak/bill are used rip apart the prey so it is easier to eat. Owls with yellow colored eyes (iris) are generally daytime huntersOwls with orange colored irises are generally dusk and dawn hunters Owls with dark colored irises are usually nighttime hunters
Behavioral Adaptation
They stay in a tree and watch their prey and then sweep down to get it.They hoot to warn each other of danger.Very quiet when they fly so they will not tell prey they are coming.They usually do not make their nests but use nests from other birds which makes it easy to move from one place to another.They are nocturnal so they can hunt at night.
Physiological Adaptation
Keen eye sight to see prey from far away.Keen hearing to hear their prey and other owls.They can turn their heads 270 degrees because they have 14 vertebrae so they can spot their prey and see predators.They have no marrow (bones are hollow) in their bones which help them fly.
