Offshore wind power is widely regarded as one of the most promising sources of renewable energy, however the expansion of offshore energy production can pose a risk to marine wildlife, including seabirds, if the expansion is not managed correctly. One seabird that is thought to be particularly sensitive to offshore wind farm developments is the black-legged Kittiwake, but a closer look at a Walney Two offshore wind farm may tell a different story. This report investigates the nesting behaviour of the Kittiwake colony found on Walney Two Offshore wind farm, providing a baseline dataset for the colony and greater insight into the impact of offshore wind farms on sensitive seabird populations. The following report was produced as part of the Marine Futures Internship; a collaborative project between Natural England, Ørsted, The Crown Estate and the North West Wildlife Trusts, which is funded by The Crown Estate and managed by Cumbria Wildlife Trust.

The Survey was carried out to quantify the number of adults, fledglings and nests present. The survey vessel first approached the north side of the substation, before heading clockwise towards the east, south and west sides, maintaining a minimum distance of 100m to avoid potential bird disturbance. Data was collected by observers on the deck of the survey vessel who used binoculars, to record the number of breeding pairs, fledglings, nests and trace nests. These counts were verified by photographs that were taken on each side of the platform to analyse nest materials, nest quality and location. The substation was divided up according to aspect to enable each section to be surveyed and mapped accurately and repeatably. Substation sides were also categorised into vertical layers in order to investigate nest position. The data was then formatted in Excel ready for analysis.
