The wyrsa looked up, startled, as the owls made another swoop.

That owl on the wall there, making noise every night.

The barred owl makes nests on tree limbs and are usually near ponds or lakes.

Chareos could not see its prey, nor whether the owl made a kill.

This ability keeps bodily movement at a minimum and thus reduces the amount of sound the owl makes as it waits for its prey.

The owl felt her enter its mind, and graciously made room.

The owl made a sound that was more like a muffled laugh than anything else.

But the owl didn't make a sound.

The owl made a wide circle around the tornado, then flew lower and over our heads.

It is reputed to be derived from the horrific sound owls make.
