An Airport is No Place for an Owl

Seeing a short-eared owl in November on the Pittsburgh International Airport, where I work as an airport wildlife biologist, was a unique occasion. However, as the number of owls grew to eight, I recognized the challenge ahead:  Like all birds of prey, short-eared owls are a recognized potential aviation hazard. Their low rolling flight and difficult-to-disperse reputation means they pose an aviation safety threat.  From 1990-2012, short-eared owl strikes with aircraft in the United States caused over $1 million in damage, and often are fatal to the birds.  Convincing them to leave would be difficult but important.

The task would be harder because short-eared owls are listed by the State as an endangered species.  Common in many areas globally, Pennsylvania is the southernmost edge of their breeding range.  These owls likely migrated from Canadian breeding grounds to winter in Pennsylvania.
