In Search of Owls

In Search of Owls

On Sunday evening, August 1, 2010, the Livermore Area Parks and Recreation Department sponsored an “In Search of Owls” event in Veterans Park. Ranger Patti Cole began the presentation with a detailed explanation of the unique features of owls.

The belief that owls can turn their heads 360 degrees is almost true. Having twice the number of cervical vertebrae as humans allows them to turn 270 degrees.

Owls have eyes that are proportionally larger than other birds when compared to body size. Being nocturnal, this assists with night vision.

Hearing is enhanced by having offset ears on either side of the head. An owl can tilt its head just slightly to hear within a larger range. The shape of the owl’s face also assists in hearing; the rounded shape funnels sounds to the ears.

The talons on an owl lock in place after grasping prey, allowing for a more secure hold on the next meal while flying to a safe place.

One of the most fascinating features of owls is their ability to fly silently. The top feather of an owl’s wings is covered with a very fine row of feathers which muffles any swishing sound made while flying.

After the presentation we ventured out to attract owls using modern technology – an amplified ipod with recorded screech owl and barn owls calls. We watched and waited for over an hour until we spotted a barn owl off in the distance, possibly close enough to have heard our recorded call. This barn owl was to represent all of the local owl population as it was the only one seen.
