Sonic and Lindsey Garven rest after Sonic did a good job chasing birds off of a field near MacDill's runway, April 7, 2014. Sonic and Garven work together to keep birds off of the MacDill airfield. Sonic loves to chase the birds. The birds are a hazard to aircraft, they can cause damage or ingested in the engines could cause a crash.
