A night owl, with a wingspan of
21.7 inches (55 centimetres), is an
ideal night hunter. Its large eyes
are lodged in the front its head.
This location is very
advantageous in its finding its
prey. Another property of its eyes
is the capability for night vision.

In addition, owls can rotate their heads three-
quarters of the way around, which further adds
to the size of their visual field. The ears of this
bird are also very sensitive. It can hear from its
place on the branch of a tree the quite noises
that a rat makes in the bushes. It can flap its
wings virtually without a sound. The owl
latches on to trees or to its prey with
large and powerful claws. One easily
sees that this creature is created as the
ideal night predator.
