We wish to thank Marine Scotland Science and the Project Steering Group for support and guidance throughout this project. We are grateful to Mike Harris who started CEH's Isle of May seabird study which has supplied much of the insight and data underpinning the models. We are also grateful to the many staff, students and volunteers who have collected data on the Isle of May, in particular Mark Newell, Linda Wilson, Jenny Bull, Suki Finney, Liz Humphreys, Sue Lewis, Chris Thaxter, Kate Ashbrook, Chris Wernham and Bethany Nelson. Many thanks also to the people who have organised field campaigns and collected data at the other SPAs considered in this project as part of RSPB's FAME and STAR projects, in particular Ellie Owen and Tessa Cole. We are also grateful to FTOWDG for allowing access to their GPS tracking and at-sea survey data. Finally, we are grateful to Chris Thaxter for processing guillemot and razorbill time activity data (Thaxter et al. 2013) at hourly scales for this project.
