  1. The referenced categories for species, habitat, season and disturbance were “Eurasian Curlew: EC”, “mudflat tideland: MF”, “autumn: AU” and “no: NO”, respectively. The abbreviations for spring, Far Eastern Curlews and saltmarsh are SPR, FEC, SM. Other abbreviations for the predicting factors refer to Table 1. Significant values are highlighted in italics
