Feathered City Terrorists or simply Pleasant Seagulls?


I used to be amused to learn Sara Jentsch’s current diatribe on gulls: Why I despise Seagulls: A Story of Humiliation. It was encouraging to find that it’s not simply in Britain that these feathered city terrorists swoop down on unsuspecting vacationers to alleviate them of their crêpes, ice cream or chips. Each summer time the British press delights in tales about big seagulls (they’re by no means ordinary-size, common gulls) attacking and robbing unsuspecting individuals, normally guests to seaside cities. That is even supposing most locations which undergo from marauding gulls have loads of indicators warning vacationers concerning the birds. Plainly the guests who’re robbed of their chips both can’t learn, or don’t suppose it could actually occur to them. It will probably, and it does. Incessantly.

Herring Gulls have large appetites

Nonetheless, there are methods of preserving the gulls at bay, in accordance with Professor Paul Graham, an knowledgeable in animal behaviour on the College of Sussex. Based on the professor, there are a variety of easy measures you can take to make sure that you’re not a sufferer of the gulls. “If the hen is within the air, making calls, and you might be frightened it’d attempt to assault you, then simply merely staring on the hen and pointing at it should cease it from coming in the direction of you.” He additionally recommends preserving your again to a wall, as this stops the gull from dive-bombing you from behind (the unseen assault). Professor Graham explains that gulls are kleptoparasites, which implies that they’ve developed to to steal meals from others reasonably than exit and forage for it themselves. 

Britain’s city gulls are typically unpopular, and it’s typically laborious to discover a phrase of their defence. Two species are concerned: the Herring Gull and the intently associated however barely extra elegant Lesser Black-backed Gull. Each are protected by legislation, whereas the 2 are additionally red-listed species which can be declining within the UK.

Herring Gulls are comfortable to nest in cities and concrete conditions

Analysis by the British Belief for Ornithology, utilizing GPS monitoring to analyze the feeding preferences of breeding Herring Gulls at a declining colony, discovered that these birds usually tend to be foraging on Mussels than pilfering your lunch. Based on the BTO, “Regardless of their fearsome status, breeding Herring Gull numbers are declining at many previously vital websites and this species has been on the Birds of Conservation Concern Crimson Record since 2009. Declines at this well-studied colony imply breeding numbers are at present roughly a tenth of these counted within the late Nineteen Eighties, when the colony peaked at roughly 11,000 apparently occupied nests.”

Based on analysis by the BTO, Herring Gulls choose to forage on the seashore

The BTO’s GPS tags revealed that the gulls most popular to feed on intertidal and near-shore habitats, and specifically Mussel beds. “Earlier research of Herring Gulls breeding at South Walney had proven the significance of landfill as a meals supply, however native ideas have since closed, doubtless contributing to the discount within the colony’s measurement. Apparently, not one of the tracked birds specialised in foraging in city habitats, so usually are not prone to come into battle with people on this surroundings, the place they are often perceived as a pest. Nonetheless, the birds’ specialisation on Mussel beds reveals the significance of managing shellfisheries in a means that meets the wants of each people and Herring Gulls in an effort to mitigate additional declines at this colony.”

Lesser Black-backed Gulls often nest in city colonies with Herring Gulls

Although conservationists might fear concerning the decline in numbers of each Herring and Lesser Black-backed Gulls, each species are way more quite a few than they had been a century in the past. In my residence county of Suffolk, Herring Gulls had been as soon as largely confined to the coast, in accordance with Claude Ticehurst’s Historical past of the Birds of Suffolk (1932). He additionally said that Lesser Black-backed Gulls had been passage migrants within the county, seen solely in spring and summer time, however very hardly ever seen inland. They didn’t breed.

Britain’s Lesser Black-backed Gulls historically winter on the Atlantic coasts of Spain, Portugal and North Africa. At present growing numbers stay in Britain all-year spherical. This hen was photographed in October 2022 close to Rota on Spain’s Atlantic coast

At present a number of 1000’s pairs of Lesser Black-backed Gulls nest within the county, whereas growing numbers overwinter, with flocks of as much as 5,000 reported inland. (I repeatedly see flocks of 1000-plus round my residence, which is 50 miles from the ocean). Herring Gulls are described by Suffolk Birds 2022 (the latest county hen report) as “quite common resident, winter customer and passage migrant”. Making an attempt to steer folks that these birds are declining and wish our assist typically falls on deaf ears: individuals don’t like large gulls.

Herring Gulls make extraordinarily noisy neighbours

Final month I stayed for per week within the Dorset city of Bridport. It’s simply a few miles from the coast, and helps a thriving colony of roof-top nesting Herring Gulls, a quantity of which had been breeding on buildings near the place I used to be staying. As I found, they don’t make nice neighbours. They’re extraordinarily vocal, their piercing calls persevering with each day and evening. They’re additionally extraordinarily messy birds: you don’t need one defecating in your automobile, or anyplace else for that matter. There are some pleasant species of gull: I actually like Little Gulls and Sabine’s Gulls, and am keen on the Widespread (Mew) Gull, too. There are some gulls that I’d actually wish to see, with Ross’s and Ivory Gulls on the prime of the listing. However I’m afraid that I’m not a fan of the 2 basic seagulls, the Herring and the Lesser Black-backed.
