Of all of the gulls that happen in Britain, there’s none that’s as pelagic because the Kittiwake. It’s a chicken that not often happens inland, and outdoors the breeding season it spends its time far out to sea. British-ringed Kittiwakes have been reported many occasions from Greenland and Newfoundland, and birds in grownup plumage are frequently seen in winter in mid-Atlantic.
In March, as the times begin to lengthen, so the wandering birds return to their breeding cliffs. Most male Kittiwakes return to the colony the place they hatched, however solely a small minority of females accomplish that, although most will nest comparatively shut by. Grownup pairs are very website trustworthy, and if their breeding is profitable, they may return to the identical colony yr after yr. Whether or not pairs re-unite after a winter wandering the excessive seas is outwardly unknown, but it surely wouldn’t be stunning if this was the case.
By the way, by Kittiwake I’m referring to the Black-legged Kittiwake (Rissa tridactyl). Black-legged kittiwakes are distributed all through the northern hemisphere, not like their smaller cousin the Crimson-legged Kittiwake (Rissa brevirostris), which is a chicken of the North Pacific and which hasn’t, so far as I’m conscious, ever been recorded in Atlantic waters. In line with eBird, “it breeds on rocky cliffs on islands within the Bering Sea, from Alaska to Russia; winters on open ocean”. In distinction, eBird notes that the Black-legged Kittiwake “breeds at excessive latitudes throughout the Northern Hemisphere, primarily in giant colonies on cliffs and different constructions overhanging water”.
Suffolk’s Kittiwakes don’t comply with the principles, for not solely are their colonies among the many most southerly on this planet, however they don’t nest on cliffs, or on constructions overhanging water. The truth is the most important Suffolk colony of all is within the city of Lowestoft, with scores of pairs nesting considerably improbably on the tower of the Roman Catholic Church of Our Girl of the Sea (under). Inbuilt 1902, the architects had been George Baines and F. W. Richards. They designed the church to be within the Arts and Crafts fashion. After all the very last thing that Messrs Baines and Richards would have thought of once they designed it was that sooner or later it could assist a flourishing colony of birds of any type, not to mention Kittiwakes.

The primary file of those good little gulls nesting in Suffolk was in 1958, when two pairs nested on Lowestoft’s South Pier Pavilion. The colony steadily elevated, so by 1970, some 32 pairs had been current. Throughout the subsequent decade numbers continued to develop, and nesting pairs unfold onto buildings within the surrounding harbour space. Kittiwakes aren’t usually in style neighbours, for through the breeding season they name each incessantly and noisily, and their droppings aren’t nice for the paintwork of vehicles, both.
Word the attractive crimson gapes of those birds
Efforts had been made to maintain the birds away, with varied methods of dissuading them employed, together with netting. Nonetheless, the birds had change into a neighborhood attraction, so Related British Ports constructed a pupose-built wall for them. Accomplished in 1988, it quickly proved in style. Nonetheless, it wasn’t ample to accommodate the rising colony, which loved unusually excessive fledging charges because of the absence of great predators akin to Nice Skuas and Nice Black-backed Gulls.
The battle between the Kittiwakes and the locals got here to a head in 2021, when BT erected nets to maintain the birds off its constructing on Surrey Avenue, as did the close by Pappa John’s Pizza. A number of unlucky Kittiwakes grew to become trapped. The ensuing publicity about their deaths hit nationwide headlines: the netting was eliminated, and BT even erected bird-friendly ledges for the Kittiwakes to nest on. This led to the institution of the Lowestoft Kittiwake Partnership (arrange by the Suffolk Wildlife Belief, along with then RSPB, the council, enterprise teams, group members and with the assistance of the native MP) which seeks to safeguard nesting birds whereas decreasing battle with companies and the homeowners of buildings within the city.

It was because of the Kittiwake Partnership that the vitality big Ørsted agreed to construct two Kittiwake motels shut offshore at Lowestoft’s South Seaside. In line with the native paper, the revolutionary designs had been “developed by a group of ornithologists, architects, ecologists and engineers” and the ensuing spectacular constructions have slender ledges and vertical sides to imitate the cliffs on which the Kittiwakes usually nest. Every tower has the capability for 500 pairs, whereas every nesting house is fitted with a sliding Perspex panel, enabling researchers to view the Kittiwakes from contained in the constructions with out the birds having the ability to see them.
The offshore Kittiwake motels had been solely accomplished final summer season, so that is the primary yr that the birds can transfer in. Decoy Kittiwakes are getting used to lure the birds, and it appears extremely seemingly that the motels will show in style.

Nonetheless, whether or not the city birds will ever be persuaded to maneuver is one other matter, for as I famous earlier, Kittiwakes are very website trustworthy. I visited the city colony on the finish of March, discovering ledges full of birds, the air stuffed with their shrill onomatopoeic calls. I didn’t handle to depend the numbers current, however my shot of the church exhibits the birds packed shoulder to shoulder, with little room for late arrivals. The cabinets on the BT constructing had been additionally nicely occupied, with hardly house for extra birds, whereas each attainable nest website close by, akin to the highest of lamp-posts (above) was additionally occupied. I a lot loved seeing and photographing them, however I’ve to be sincere: I’m undecided that I’d need them nesting on the roof of my home.
