This study investigates the short-term effectiveness and long-term limitations of technological bird deterrent systems at Trabzon International Airport (TIA), with a focus on the responses of resident bird species. The research, conducted from August 2021 to November 2022 by testing the devices included a bioacoustic system (Bird-Xpeller® PRO), an ultrasonic unit (Bird-K Imti 040), and a golden jackal replica emitting predator calls, all powered by a portable solar battery. Observations were carried out using camera traps, binoculars, and direct field monitoring across three critical zones within and around the airport during both migratory and non-migratory periods. The results showed that resident bird species, particularly hooded crow, yellow-legged gull, and rock dove, quickly adapted to all tested deterrent systems. While initial deterrent responses such as short flights and low-altitude circling were observed, most birds returned within 10–30 minutes and often landed near or on the devices. Migratory birds showed slightly longer avoidance periods but gradually habituated as well. Additionally, short vegetation near deterrents facilitated landings. The study concludes that while technological deterrents may provide short-term disturbance, their stand-alone use is insufficient for sustainable wildlife hazard management. The findings reveal that technological systems alone fail to provide sustainable control due to rapid habituation. Therefore, integrated wildlife management strategies are needed. These should include habitat modifications, behavioral interventions (e.g., trained dogs), and adaptive vegetation practices—such as maintaining taller grass in non-migratory seasons to localize resident birds, and lowering it before peak migration to reduce habitat attractiveness.
