Scientists Confirm: Shouting Effectively Deters Seagulls
The presence of seagulls, particularly herring gulls, at coastal areas is a frequent concern for beachgoers. Recent research highlights that shouting can effectively deter these birds, offering a practical solution for those enjoying outdoor picnics and meals.
Research on Shouting as a Seagull Deterrent
A study conducted by a team of researchers explored how urban herring gulls respond to different vocalizations. Previous findings indicated that these gulls perceive shouting, especially from men, as a threat. In an experiment, recordings of a male voice shouting phrases aimed at protecting food were played back. The results showed that gulls reacted similarly to the sound of alarm calls from other gulls.
Vocal Cues and Gulls’ Behavior
The research team set out to understand if herring gulls are generally sensitive to human vocal cues or specific speaking methods. They hypothesized that gulls might respond more to aggressive tones than gentle ones. To test this, five British men recorded two versions of the same warning: one in a shouting tone and another in a neutral voice.
- Shouting affected gull behavior more significantly than normal speech.
- Gulls moved away quickly when shouted at, compared to waddling away when merely spoken to.
The trials took place in several Cornish coastal towns, known for gull disturbances. The gulls were lured toward a container filled with fries before playback of recorded sounds began.
Control Trials and Findings
A control group utilized recordings of European robins to evaluate gull reactions to non-threatening sounds. The gulls’ responses indicated a marked difference in behavior when exposed to shouts and speech compared to the robin calls. Those subjected to shouting exhibited more avoidance behaviors, reinforcing the idea that tone plays a critical role in their reactions.
Understanding Herring Gulls’ Behavior
Although the research results may align with common pet behavior, the dynamics differ given that herring gulls have only begun living near humans in recent years. The study suggested that these gulls have learned to associate loud, aggressive vocalizations with danger rather than with nourishment.
Conservation Considerations
Interestingly, despite their presence in coastal cities, herring gulls are on the RSPB’s red list for species at risk. Their populations have halved over the past five decades due to environmental pressures, including food shortage and predation.
Practical Applications
This new understanding of herring gulls and their responses to human vocalization offers non-violent strategies for managing interactions with the birds. Previous studies also suggested simple staring could be an effective method for deterring gulls from stealing food. Moreover, one of the easiest ways to minimize conflict with herring gulls is to avoid feeding them.
These findings could enhance the outdoor experience for beach visitors, providing effective strategies to keep seagulls at bay while enjoying summer picnics.
