The Owl

Who, who, I hooted from the tree.
I am awake and it's half past three.
Nocturnal is the best time for me.
With my night vision, I see movement instantly.
When I catch movement or hear a sound,
I'll spring from the limb, down to the ground.
My movement is quick, so please don't worry.
Pouncing on a prey, I do in a flurry.
