Map of sampling locations and STRUCTURE results at K = 3 for eastern Kentish and White-faced Plover populations. The inset shows global distribution of Kentish and White-faced Plovers22: green areas demarcate year-round resident populations of Kentish Plovers, purple shows breeding ranges of migratory populations and blue areas show wintering regions; the thin dotted line (• • •) outlines the presumed breeding range of White-faced Plovers and the stippled line (−) demarcates their known wintering range. Cross and open diamond refer to sampling localities in Spain and far western China respectively. Samples collected during the breeding season (May–July) are outlined in red whilst those collected during the non-breeding season are outlined in blue. Sampling dates for Taiwan are unknown and thus lack outlines. Sampling locality acronyms are as follows: QH – Qinghai, QD – Qinhuangdao, JP – Japan, SH – Shanghai, YJ – Yuanjiang, WZ – Wenzhou, WL – Wenling, FZ – Fuzhou, PT – Putian, XM – Xiamen, TW – Taiwan, B-Z – Beihai-Zhanjiang.
