Spring migration dynamics and sex-specific patterns in stopover strategy in the Wood Sandpiper Tringa glareola

摘要: Due to being a virtually monomorphic wader species, migration dynamics and sex-related patterns in the Wood Sandpiper (Tringa glareola) have rarely been investigated. We captured spring migrants at an important stopover site northeastern Austria. Birds were individually color-marked, sex was determined by analysis of DNA from tail feather material. Among temporary residents (birds seen again after day capture), males migrated on average 3 days earlier than females. However, since sexes did not differ fat score, length stay proportion transients capture) residents, we suggest that females adopt similar strategies spring. The large number as well shorter durations later indicate Sandpipers minimize time this stage their northbound migration. Temporary season exhibited lower stores ones. Nevertheless, even progress had accounted for, assume may afford exhibit individual flexibility strategy use sites, especially early season. This variability be necessary adaptation cope with possible varying environmental conditions dynamic unpredictable inland sites. After having reached North Mediterranean regions, mean body mass gradually increases during successive stopovers, indicating follow ‘hopping’ strategy. emphasizes high conservation value small artificial mudflat pools stepping stones order maintain continuous network wetland habitats for continental migrant.
