 They are parapatric and replace each other geographically; stray birds of either species may settle down with breeders of the other and hybridize.Hybridization has also been reported between the common sandpiper and the green sandpiper, a basal species of the closely related shank genus "Tringa".The common sandpiper was one of the many bird species originally described by Linnaeus in the landmark 1758 10th edition of his "Systema Naturae", where it was given the binomial name of "Tringa hypoleucos".
