Abstract
In the North Sea Wadden Sea, Dunlins of the two subspecies Calidris alpina alpina and C. a. schinzii occur on migration. In this study, I investigate the putative breeding origin of Dunlins caught at the Sylt/Romo Wadden Sea during peak migration in spring and autumn. Genetic variation and haplotype composition was assessed by sequence analysis of the mitochondrial Control Region. A comparison with population genetic measures of breeding populati ons suggests that Dunlins caught in spring (May) predominantly belong to "a lpina" while a high percentage of specimens sampled in autumn (September) b elong to "schinzii" This study demonstrates that the putative origin of mig rating birds can be assessed by quantitative genetic measures, even in the absence of exclusive genetic markers.
