Competing Interests

This research was co-supervised by employees WP of the Royal Society for the Protection of Birds (RSPB) and NI, RS, and GP at the Centre of Ecology and Hydrology (CEH). Data for pesticide usage were obtained via an employee DG at Fera Science Ltd. The role of DG was to ensure that usage data were correctly interpreted, but Fera Science Ltd. did not influence the research undertaken in any way. This does not alter our adherence to PLOS ONE policies on sharing data and materials.
