From profiteroles to moles: project uncovers gulls' surprising diet
Gulls are renowned for snatching chips from tourists' hands, but a scientific project has revealed the greedy birds also like to tuck into moles and quench their thirst with seal milk. The discovery was among several surprising findings made by a University of Salford ecologist, Dr Alice Risely, after she set up a project asking the public to send her pictures of seagulls eating. The project, named Gulls Eating Stuff, has received submissions from around the world showing the birds' varied diet. From sandwiches to profiteroles and starfish to coot chicks, it seems a gull rarely goes hungry. One person even submitted an image of a gull eating an unfortunate mole. Risely, who has been researching gulls' diets to better understand them, said: 'I've seen photos of gulls suckling the milk from seals. There's also a real problem in South America with the different species [of gull] there. They've got this really nasty habit of landing on sleeping whales and eating [their] flesh.' Some gulls, including lesser black-backed gulls, are migratory so may learn eating habits elsewhere and bring them to the UK. 'The thing with gulls is, because they're very smart these behaviours spread culturally,' Risely said. She added that gulls had increasingly shifted from living in natural habitats in coastal regions to more urban areas. While researchers have studied gulls in their natural habitat extensively, less is known about the habits of those that have moved into urban areas. A way to understand this shift could be through their eating habits. Although the project was in its infancy, Risely said the findings so far had shown that while gulls happily take advantage of the seaside snacks left behind by humans, they are very much predatory animals. 'Hopefully what will come out of it in terms of public education, it's the gulls are not just scavengers, they're predators,' she said. 'A lot of them are actually out there eating quite natural prey items; eating worms, but also eating chicks and some small mammals, and kind of acting like a normal wild animal should.' There did seem to be a connection in the gulls' diet regardless of their habitat, Risely said. 'What people don't know, which I'm seeing in my own research, is just how important earthworms are. Yes, they are eating baby birds and mammals, but probably by far the most important food item for all gulls is worms. It doesn't matter if you're a town gull or a sort of trad gull, you will in the morning go to a field and eat worms and invertebrates.' The project's global reach has meant gull diets can be observed on a larger scale, which may help researchers to work out where eating trends began.

Scientists probe gulls' 'weird and wonderful' appetites
From pilfering chips to swallowing whole starfish, gulls are known for their voracious appetites. However, one scientist was so astounded to see pictures on social media of gulls eating "weird and wonderful things" that she launched a citizen science project to study their shifting diets. University of Salford ecologist Dr Alice Risely wants people to upload their snaps of hungry gulls to the project's website, Gulls Eating Stuff. "By studying gulls' diet, we can learn more about their behaviour, their role in ecosystems and the pressures they face in a changing world," she said. UK seabirds face threats from warming oceans, overfishing and avian flu. Gull populations are in decline, with several species on the UK red list of conservation concern. Some gulls are coming to live closer to people, adding human leftovers to their natural menu of fish, crabs, starfish and earthworms. The birds may be flocking to urban areas to find food to feed their chicks during the breeding season, switching back to a natural diet once their youngsters have fledged. Alternatively, gulls may be relying on human leftovers for much of the year as the natural food supply dwindles. "The fact is we just really don't know – there is very little data," said Dr Risely. "This is why we wanted to exploit this resource of online photos to try and help us understand what the gulls are eating, and if there are any patterns we can find." One particularly striking photograph shows a gull eating a baby puffin. It was taken by scientist Samuel Schmidt on a trip to the Farne Islands in Northumberland. Getting more information on what gulls are eating - in proximity to people and as the climate changes - "could be very enlightening", he said. "The gull wasn't malicious; it was just hungry," he added. Gulls are known to eat other birds, including pigeons. The UK is known for its huge colonies of seabirds nesting on cliffs - but populations are plummeting amid a host of pressures, from climate change to a lack of food. Five seabirds added to UK red list of most concern Gulls are in trouble in their natural spaces - and some species, such as herring gulls and lesser black-backed gulls are seeking refuge in coastal cities. There is very little data on the number of urban gulls - but natural populations are regularly monitored, showing big declines. Three gull species are on the UK red list of conservation concern: The great black-backed gull - a very large gull with black wings and a powerful beak that nests around the coast, on clifftops, rooftops and islands The common gull - a medium-sized gull scarcer than its name suggests that nests around lakes in the north of England and Scotland The grey-backed and pink-legged herring gull.
