The extensive overlap in morphological characters between populations of Dunlin Calidris alpina imposes problems of determining the origin of migrating and wintering birds. The morphology of the birds also varies between the sexes, and the sex of a D

Sexual size dimorphism among 57 species in the shorebird family Scolopacidae is evaluated in relation to parental role division during breeding. Normal size dimorphism, i.e. the female being smaller than the male, occurs in species where the female h
