This resource includes a series of spreadsheets which provide visual tracking data from Ythan Estuary, Sands of Forvie and Meikle Loch Special Protection Area (SPA), for Sandwich terns. The data cover the 2011 breeding season. These data were collected as part of a wider JNCC marine SPA identification programme, in conjunction with the four country nature conservation bodies (CNCBs). The data were used to quantify usage of the marine environment by the four larger tern Sterna species around their breeding colony SPAs in the UK. The data must be used in conjunction with [JNCC Report 500: Quantifying usage of the marine environment by terns Sterna sp. around their breeding colony SPAs (Wilson et *al*. 2014)](https://hub.jncc.gov.uk/assets/926cdbbd-c384-42a9-b9e5-81abd778bbd0).
