Wintering Purple Sandpipers Calidris maritima in Troms County, Northern Norway
A total of 10, 650 Purple Sandpipers were counted on small islands and skerries off the outer coast of Troms and 953 were counted on 220 km of fjord coastline. The total wintering population in the study area was estimated at about 18,000. Seven samples of Purple Sandpipers were cannon-netted during...

| description | A total of 10, 650 Purple Sandpipers were counted on small islands and skerries off the outer coast of Troms and 953 were counted on 220 km of fjord coastline. The total wintering population in the study area was estimated at about 18,000. Seven samples of Purple Sandpipers were cannon-netted during early November 1988. There were differences in age and sex structure between localities. The overall bias towards males (60%) was believed to be due to the females being elsewhere rather than caused by greater mortality among females. Adult birds were heavier than first-year birds and Norwegian birds were heavier than Scottish birds. Of adult males 31% and of females 10% were still moulting primaries in November. Site fidelity within and between winters was recorded. The population is thought to be composed of birds which breed in the U.S.S.R. |
