Notes on migration dynamics and biometry of the Wood Sandpiper (Tringa glareola) at the sewage farm of Münster (NW-Germany)

摘要: This paper summarises results of almost daily counts Wood Sandpiper and an extensive ringing colour-marking scheme at the sewage farm Munster from 1969 to 2000. In course this 32-year period, migration phenology tended have advanced in spring, delayed autumn. While roosting numbers remained stable they decreased autumn, which is partly attributed changes local habitat quality. A total 1432 Sandpipers were ringed measured. Analysis biometric data revealed larger wing tail length juveniles due feather wear adults, whereas bill nalospi longer adult birds. birds had wings tails, but lower body mass than adults caught with active primary moult so far hardly been reported other sites Central Europe, our indicate that a low number regularly start remiges early stage autumn migration.
