This study makes use of previously collected aerial survey data, and uses a statistical technique called power analyses to assess whether current aerial survey methods allow changes in bird numbers to be detected, given that there are large background fluctuations in seabird numbers at any given site. Five species, two of which were combined due to the difficulty of separation were selected for analysis: red-throated diver (Gavia stellata), common scoter (Melanitta nigra), sandwich tern (Sterna sandvicensis) and lesser and greater black-backed gulls (Larus fuscus and L. marinus). Maclean, I.M.D., Skov, H., Rehfisch, M.M. and Piper, W. (2006) Use of aerial surveys to detect bird displacement by offshore windfarms. BTO Research Report No. 446 to COWRIE. BTO, Thetford.

Abstract | The abstract provides a clear and brief statement of the content of the resource. | This study makes use of previously collected aerial survey data, and uses a statistical technique called power analyses to assess whether current aerial survey methods allow changes in bird numbers to be detected, given that there are large background fluctuations in seabird numbers at any given site. Five species, two of which were combined due to the difficulty of separation were selected for analysis: red-throated diver (Gavia stellata), common scoter (Melanitta nigra), sandwich tern (Sterna sandvicensis) and lesser and greater black-backed gulls (Larus fuscus and L. marinus).

Lineage | Lineage includes the background information, history of the sources of data, data quality statements and methods. | In this report we make use of existing aerial survey data and use power analyses to assess whether the current DTI aerial survey scheme can be used to assess whether changes in bird numbers occur, given that there are large background fluctuations in seabird numbers at any given site. Four taxa were selected for analysis: red-throated diver (Gavia stellata), common scoter (Melanitta nigra), sandwich tern (Sterna sandvicensis) and lesser and greater black-backed gulls (Larus fuscus and L. marinus). Aerial surveyors are not usually able to distinguish between these two large gull species. In addition, we tested the importance of using a higher resolution of collected distances in relation to the detection probability of target species during current DTI aerial survey |
