Metadata: 2025, North West Wildlife Trust, Marine Internships, Kittiwake Nesting in Irish Sea
Abstract:
Here we report the monitoring of Black-legged Kittiwake (Rissa tridactyla) on offshore wind farm (OWF) infrastructure in the Irish Sea off the Cumbrian coast. The monitoring of the Walney 1 & 2 offshore substations (OSS) continued into its third year, including a trial deployment of timelapse cameras. We also report the first census of breeding kittiwakes on turbine jackets at the Ormonde OWF. The 2025 counts at Walney 1 & 2 OSSs were similar to previous years, indicating a superficially stable population and potentially indicative of well-established colonies with reduced growth. The trial of timelapse cameras indicated their suitability for future monitoring on the substations and provided data on nest phenology, potentially confirming anecdotal evidence that offshore breeding is delayed. The census of Ormonde found 15 apparently occupied nests (AON) restricted to a single turbine jacket but with adult kittiwakes roosting throughout the wind farm. However, survey limitations prevented productivity estimates; continued monitoring of the kittiwake population within the arrays at Walney and Ormonde will further improve our understanding of the colonies. 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.

| Lineage | Lineage includes the background information, history of the sources of data, data quality statements and methods. | Original sources, collected by Abi O'Leary and Alex Wright (authors), and Orsted and Natural England volunteers/employees (Bart Donato, and Harry Cale) between 06/06/25 - 20/08/25. Permission to collect granted by Orsted and the OFTO. Accuracy - known errors - some blurry photos caused by different people collecting data. These were included in the AON count as this was still accurate. Complete data set, consistent values, and recent data. Limitations caused by weather - delayed survey dates. software - dotdotgoose used to count birds and nests. |
