Seagulls will stop at nothing to steal your fry (or your dog), but fortunately, new research refines key techniques to protect your food from sea birds.
When you think of a seagull, chances are that you are drawing a herring gull. Brown and white birds on pink legs, peeping from the shore and gliding above the head of the beach. Sometimes, they dive into the water to scoop sea critters – and, sometimes more and more, birds will also seek ‘prey’ from unsuspecting humans, who try to enjoy the day by the sea will do.
But researchers have a new idea on how to stop seagulls from sipping your lunch: Look at the bird directly.
Yes, the way to protect yourself and your food from these infamous scavengers is to enter a staring contest with the enemy.
According to a recent study on birds, herring lanes are detected when a person is watching them. Scientists discovered this disruptive ability when trying to measure how birds react to humans based on the formation of the surrounding area. Their investigations reveal that it is easier to approach urban streets than their rural counterparts.
But in both urban and rural settings, If someone was watching them, the streets soon ran away.
The researchers studied 155 shells, which included both juveniles and adults in each type of environment. Scientists approached the Goole by keeping their eyes on the ground, either looking directly at them or facing them.
Researchers found that an attentive human escape response seems innate: newborns were also as likely to react to human gaze as older birds.
When rural lanes were not directly seen, they allowed humans to move closer to an average of 6.5 feet before setting up. For urban streets, the effect of being uncontrolled was even stronger; Non-sighted humans can be more than 8 feet away from the townspeople.
The research was published online on 4 September and will appear in the October 2020 issue of the journal animal behavior.
Process refinement – New findings appear on previous work that focuses on how humans react to the attentive eyes of humans.
A 2019 study led by the same researcher, University of Exeter PhD student Madeleine Gaumas, explored a similar idea. In that study, researchers either looked at birds or looked away. He found that while watching a bird he ate a bag of French fries and reduced the time it takes for the bird to fly.
The new study has a similar levitation, which refines the method of directing eye contact to track the ground.
Goumas said in a statement, “In our new study, the experimenter approached Gool facing and only changed the direction of his eyes.
“We wanted to know that the streets pay particular attention to the direction of the human eye, and this is true for teenagers as well as adults – so their opposition to human gaze is with people for months or years. Not the result of negative interactions. ”
Birds in the human world – Birds are surprisingly good at adapting to the human environment. Gools, pigeons and crows have all come to live among humans using different living mechanisms.
The streets have developed Big brain To better navigate the city and other human-oriented places. Meanwhile pigeons trust one strength in numbers Strategy, to ensure that their youth survive. Those findings came out in a March 2020 study.
We may see more of these curious conversations in the future. Herring gulls are becoming an increasingly strong presence in urban areas, researchers say – it is inevitable that they will interact with humans. And despite your personal feelings towards these pesky birds, eventually, work can help protect them.
“The increasing number of herring gulls in urban areas may make them appear more common than they really are,” Goumas said.
“The species is indeed in decline in the UK, and we hope that human-goole interactions will contribute to our ongoing research conservation efforts.”
abstract: With the increasing human population and expansion of urban settlements, wild animals are often exposed to humans. As a threat to humans is a neutral presence or source of food, animals would benefit from assessing the potential potential risk to respond appropriately. Herring girls, Lars Arengates, Are breeding and developing rapidly in urban areas, and thus have many opportunities to interact with humans. We have recently found that herring gulls take longer for food when viewed by a human. However, it is not known whether the experience of human gaze avoidance arises from experience with humans, and whether individual differences in accountability are the result of differential risk. Here, we tested whether herring gulls’ response to human gaze varies according to their age group and the urbanization of their habitat. We measured the flight initiation distance of gulls when an experimenter made contact with a direct or a gaze gaze. Neither gaol age nor urbanization significantly affected the impact of human gaze on flight initiation distance. However, as a recently fledged juvenile strongly responded to the experimenter’s gaze, encountering human gaze may not require extensive exposure to humans to develop. Goals in urban areas may be approached more closely than those in rural areas, consistent with findings from other species. These results indicate that gaze dispersal is present early in development and that exposure to humans may affect the reactions of gulls to perceived risk from humans. Examining the processes that produce distinct differences in human reactions will provide further insights into human – wildlife interactions and the impact of urbanization.
