South Walney - Nesting Season Preparation

Nesting Season
Spring has finally arrived and with it, changes are occurring. Flowers are blossoming, days are lengthening and here at South Walney Nature Reserve, birds are carrying sticks and feathers and nests are popping up along our beaches which means that nesting season has begun.

Nesting season is the most important time of year. The productivity of our birds is highly important and to assist them during this season, a lot of preparation is undergone during the Autumn and Winter months.

Nesting Season Preparations
Funding provided by ‘LIFE on the Edge’ (also known as LOTE) helps substantially at South Walney nature reserve when it comes to nesting season. LOTE is a Life Nature project which is lead by the RSPB and National Trust. This project aims to improve the quality of target coastal areas as well as providing recommendations for longer term coastal habitat management and/or creation, with focus on little tern, oystercatcher and ringed plover. LOTE have provided South Walney with equipment for electric fences such as solar panels and energisers, monitoring equipment such as trail cameras and thermal scopes and permanent hybrid fencing. LOTE also provides funding for a seasonal shorebird warden to work with the sole purpose of protecting coastal nesting birds. With the help of LOTE, we at South Walney are able to provide protection to nesting coastal birds throughout the season.

Preparation for nesting season begins in late August / early September. At this time, we start checking our permanent fences for damage and repairing them. Debris is removed and the gates are shut to stop livestock from entering. Holes in the fence are repaired, wire is replaced and holes dug by predators into the fenced area are filled in. The area around the electric fence is cut back with a brush cutter to reduce interference with the wires. The inside of the fence is also brush cut to create the correct nesting habitat. The fence is now ready to be made live closer to the start of the season.

During the nesting season, temporary electric fences and signs explaining what we are protecting are erected. Before this, the area around the perimeter of the fence is brush cut and litter picks are completed. During this season and the previous season, an area of land to past the boundary wall of the reserve to the north was fenced. This land was kindly temporarily loaned to South Walney Nature Reserve, as little terns choose this location to nest. The habitat is shingle and sand, close to the sea which is a perfect location for terns to nest and fish.

To provide more habitat for nesting coastal birds, a tern raft is moved into place, floating in the pool of the oyster farm. The anchors are dropped, a camera is installed and the raft is ready for occupants. There is a permanently placed raft which is used by the same Oystercatcher pair each year. The parents are currently sitting on eggs there now!

Chick shelters, nest cages and cameras are important to protect vulnerable chicks and adults from predators and extreme weather. Shelters of different shapes (for different chicks) are placed on the tern rafts, inside the fences and along the beaches to provide shelter and safety to chicks. Cameras are crucial for monitoring wildlife. They are placed directly on nests and at crossing points to catch predators. Cameras are placed out early in the season and checked regularly throughout the season.

New to 2024
A new sound lure and hand-crafted little tern and herring gull decoys were created in 2024. In an attempt to attract a mixed gull colony of herring and lesser black backed gulls to nest in a new location, 10 adult and 6 juvenile herring gull decoys were created and placed in a temporary 8 strand fenced area. This fence was put in place at the start of the season with decoys and a trail camera, and has successfully attracted first year herring gull visitors since the addition of the decoy birds. We hope to see these gulls return next nesting season! To attract little tern, 40 little tern decoys were crafted and placed on the tern raft, in the temporary 12 strand fence to the north of the reserve and in the fenced area on Foulney island nature reserve. In combination with the decoys, a sound lure was created and is played on loop in the daylight hours. This has successfully attracted 12 pairs of little terns and we are hoping to see chicks in the next couple of weeks.

Good Luck, Birds!
Now that fences are live, decoys and sound lures are in place and cameras are being regularly checked, it’s up to the birds to raise their young. We wish them the best!
