Want seagulls to stay away from your food? Shout at them, researchers say
Sweet talk won’t get you far if you want to scare off a seagull trying to snatch your food. Try shouting.
Researchers set out to find if a man’s voice was enough to deter bandit gulls from their penchant for purloining food and found it was effective if delivered with more urgency. They placed fries in a box in towns across the southwest coast of England and tested how 61 European herring gulls reacted to recordings of a robin’s song, a male voice saying, “No, stay away, that’s my food,” and a voice shouting those words.
Previous research had shown that gulls could be dissuaded from snatching snacks by shouting — the louder, the faster they fled. But the new study, published Nov. 12 in Biology Letters, measured the difference between speaking and shouting if both were played at the same volume.
The birds tended to walk away from the speaking voice, but flew away from the shouting, suggesting they differentiated between the acoustic properties of the vocalizations.
