INTRODUCTION
Physical Features Owls are many different
colors most are brown or gray
There are two different types of owls
Barn owls have heart shaped faces
Typical owls have round faces Ears are slits Have nostrils instead of
noses called nares They have talons which are
really sharp nails Big eyes are set in front of
face weigh up to 4 lbs Is about 22 inches high
Habitat/Climate
Owls live everywhere except AntarcticaNot picky about climate Roosts (which is a nest) have to be near foodLikes cold, warm, and hot climateSome owls dig burrows
Landforms
Landform must have trees to live inLive in North AmericaTypical owls live away from humansBarn owls live near humansMost owls live in forestsLive in forests, prairies, mountains, swamps, and deserts
Lifespan/Endangered Not an endangered
species Live up to 20 years in
captivity The great horned owl
lives up to 13 years or more in the wild
How long they live depends on the type of owl
People cut down owls homes but they are still not endangered
They are carnivores (which means they only eat meat)Eat insects, rabbits, mice, and skunksUse beaks to tear meat from preyGrabs prey with sharp talonsWings have fringes that makes them silent to sneak up on preyReturn to perches to eat
Food
Predator/Prey
Predator Humans Eagles Big birds Foxes
Prey• Mice• Skunks• Young deer• Fish• Rabbits• Insects
Reproduction
Hatch from eggsHatch three days apartCovered with fluffy feathers called downEat all the timeFemale owls lay 3 to 12 eggsStart to fly at six weeks old
BehaviorTufts on ears show feelings Sleeps standing upTwist necks backwardMates preen each other by rubbing each other with their beaksQuiet while huntingThey are fast flyers and can fly up to 40 miles an hour
Physical Adaptation
Sharp talons help grab preyEyes are big to let in more lightColored feathers help owls camouflage in habitatHooked beak helps to tear up meatWings help owls fly quickly and quietly
Behavioral Adaptation Hunt alone to find more food Is nocturnal because prey is more active at night Twist necks so it can look around Spits up prey’s bones and fur in pellets so that it won’t get
sick on the bones Eats food whole so they don’t have to waste their time
picking out fur and bones
Physiological Adaptation
Have hollow bones which makes them lighter and easier to fly
Has binocular vision so it can see things in three dimension which helps them spot their prey
One ear is higher then the other so it can find out exactly where sound (and prey) come from
Lots of rods in eyes to help see in dark Bones are fused to support weight on ground
