There have been a variety of visual repellent and harassment techniques used in airport wildlife management. They include using birds of prey and dogs, effigies, landing lights, and lasers. Birds of prey have been used with great effectiveness at landfills where there were large populations of feeding gulls (Cook et al. 2008). Dogs have also been used with success as visual deterrents and means of harassment for birds at airfields (DeVault et al. 2013). However, airport wildlife managers must consider the risk of knowingly releasing animals in the airport environment. Both birds of prey and dogs must be monitored by a handler when deployed and must be cared for, when not deployed. Airport wildlife managers must consider the economics of these methods (Seamans 2001).
