Red Knot (Calidris canutus) Science Article 7
Studies carried out in northern Taimyr in 1982-84 and 1990-92 were combined with data from other sources to describe the breeding distribution and densities and the migration of Knots at Taimyr Peninsula, north-central Siberia. Morphometrics, recent ring recoveries, dates and directions of migration all support the idea that Knots breeding at Taimyr pass through western Europe to winter most probably in Africa. They also confirm the suggestion that Taimyr cannot harbour the entire flyway population and that an unknown breeding area is still to be discovered in Siberia. On the basis of discriminant analyses of linear dimensions formulae to sex Knots were derived; maximum wing length and bill length were the best predictors.
