Why is Foulney important?
Foulney Island Nature Reserve is comprised of a shingle spit within Morecambe Bay SPA connected (via manmade causeway) to the mainland. The reserve is home to several wintering bird species such as knot, dunlin and wigeon and is an important breeding location in the spring and summer for shorebirds such little terns, Arctic terns, ringed plovers and oyster catchers as well as other bird species such as pied wagtails, meadow pipits, eiders and skylarks.
The terns that choose Foulney as their nesting grounds are protected species and they are in decline. It is so important to offer them a safe place to lay their eggs and raise their chicks as they are easily disturbed by human recreational activities, dogs, aerial and ground predators (such as sparrowhawks and foxes). Their nests are vulnerable as they nest where there are no visual obstructions to allow them to watch for predators but this means that they nest out in the open, making their chicks and eggs susceptible to predation. Their eggs are at risk of being trampled by people, as their camouflage is very successful. Terns nest on shingle and require close access to the sea to feed. That’s what makes Foulney the perfect place for them. Terns return to the same colony to breed in most cases and Arctic tern travel 22,000 miles on their migration. This special little island hosts these incredible birds and it needs to be protected.
Breeding Season Preparation
Preparation for breeding season on Foulney Island is an intense operation! For this year, the main island was turf stripped to provide extra habitat for shore nesting birds. This new shingle area was fenced off to protect the birds using it to raise their young, from ground predators such as foxes, rats and hedgehogs. Turf stripping involves the removal of the top layer of vegetation and in this case, changing the habitat to shingle. The vegetation was then buried beneath the layer of shingle. This area has been used this season by eiders, ringed plovers and oyster catchers who’s chicks began hatching recently, proving the success of the change in habitat! Skylarks and meadow pipits also benefited from the ground predator protection in this area as they too nested here, inside the fence on the edge of the shingle where vegetation remains.
In preparation for the electric fence the vegetation was strimmed. Insulator stakes were knocked into the ground and electric wires passed through the insulators. To prepare the public, signs were put up in the carpark, the causeway and on the island stating that dogs are not allowed and explaining why, and the rope fence to fence off the beach area, where the birds nest, was put up. Lastly, the caravan was put in place. Then it was time to begin surveying!
Warden life on Foulney
Hi! I’m Bekka, and I’m this year’s seasonal warden on Foulney island nature reserve. This beautiful little island reserve is home to many species of breeding birds over the summer including oystercatchers, ringed plovers, eider ducks and little terns. In addition to the birds, the island is home to and visited by mammals such as grey seals and voles; as well as insects such as butterflies and moths.
Sharing an island with such beautiful wildlife is an amazing experience. Being the only person living on an island might seem lonely, but I have plenty of fishermen to chat to, and of course the wildlife! During the season I have been lucky enough to experience finding nests and watching parents lovingly incubate their eggs, and have watched eggs hatch into beautiful chicks. Watching eider females with crèches of up to 30 ducklings swimming across the water and oyster catcher parents leading their chicks across the shingle are sights that will never get old.
As the warden, I spend my time monitoring eggs, chicks and adults, checking trail cameras and engaging with and educating the public. Explaining to the pubic the importance of reducing disturbance to nesting birds is an extremely vital part of my job. The natural threat response in nesting shorebirds is triggered by the public and their recreational activities, especially when dogs are involved. When threatened, shorebirds are forced to flee, leaving eggs and chicks vulnerable to predation, and forcing the adult bird to expend energy which should be used in incubation or finding food. In the worst case, an out of control dog can kill shorebirds, which unfortunately occurred on Foulney this season. It is so important that our shorebirds are protected. We all have our part to play!
Now that chicks are hatching we are well into the season. Fingers crossed that all goes well here on Foulney island!
