We found some evidence that stationary radar changes movement behaviors. These increased movements may be an indication that birds were attempting to avoid radar microwaves, as in Wasserman et al. (1984a). There are also studies on other frequencies of electromagnetic radiation over much longer time periods that showed population declines and changes in the distribution of species during the breeding season (Balmori and Hallberg, 2007, Everaert and Bauwens, 2007 and Rejt et al., 2007). These avoidance behaviors in response to radar could potentially be exploited in combination with other stimuli, like visual cues, to develop deterrents for areas of airport property close to radar. However, other studies using a similar X-band radar without a visual cue have shown that radar alone does not alter the behavior of migrating birds (e.g. Bruderer et al., 1999).
