Competing Interests

Moreover, the authors received financial support (payments of tracking collars and GPS collar data fees) from Sea World and Busch Gardens. The authors explicitly declare that this does not alter the authors' adherence to PLOS ONE policies on sharing data and materials. External support agencies had absolutely no role in the design, analysis or interpretation of the study, nor did they in any way influence the preparation of the manuscript or any statements made by the authors. Co-author Dr Ken Stratford is the founding Director of Ongava Research Centre. As part of this study, he did not receive any funding towards his salary or his services. Dr Stratford's involvement in this study is entirely academic and had no commercial component. None of the three authors have competing commercial interests pertaining to this manuscript.
