Study Finds Yelling May Be Most Effective Way to Scare Away Gulls
A recent study conducted by researchers at the University of Exeter has found that a loud, firm yell may be the most effective way to deter herring gulls from stealing food from humans. The experiment involved placing a portion of chips in an area where gulls were likely to find them and then playing three different recordings: a male voice shouting "No, stay away, that's my food!", the same voice speaking the words at a neutral tone, and birdsong from a robin.
The results showed that nearly half of the 61 gulls tested flew away within one minute after being exposed to the shouting voice, while only 15% took flight when listening to the speaking male voice. On the other hand, 70% of the gulls stayed put when hearing the robin song.
According to Neeltje Boogert, a researcher at the Centre for Ecology and Conservation, urban gulls were more vigilant and less likely to peck at the food container when they heard the shouting voice, but more likely to fly away. In contrast, the speaking male voice seemed to stop them in their tracks, but shouting was more effective at making them take off.
The study's findings suggest that gulls are paying attention to the tone and pitch of human voices, which is a novel discovery in the field of animal behavior. The researchers believe that this could be an evolutionary adaptation to humans, as gulls have been domesticated around humans for generations.
Gladly, the study highlights the peaceful and non-violent methods available to deter gulls without causing them harm. Future research may explore whether a female voice has a similar effect on gulls.
