OWLS ARE NOCTURNAL

MEANING THEY ARE ACTIVE AT NIGHT

THEY ARE EXPERTS AT CATCHING PREY

  • They have talons
  • They have binaural hearing
  • They fly almost silently because of their soft feathers

Having big eyes helps the owls see better because they hunt in the dark.

Owls have too many rods in their eyes to move, but they can rotate their head up to 270 degrees around.

OWLS EYES DONT CONTAIN CONES

THIS MEANS THAT THEY PROBABLY CANNOT SEE COLOR

Owls have binaural hearing: one ear is higher placed than the other. This allows the owl to sense the prey's elevation so it can locate it and attack it.

OWLS CLAWS

THEY ARE CALLED TALONS

Owls have feathers all the way down their legs to protect them from prey trying to bite them in the air.

Owls fly near silently because the design of the feathers and their soft texture reduces noise.

Owls don't lay all their eggs at onece. They lay them at two day intervals so they hatch two days apart. This eases the feeding burden.

The owlets have to move out at nine weeks old because the food population has been depleted and there isn't enough for everyone.

Barn owls can live up to 20 years, but few live that long because there isn't enough food or because the harsh weather.
