To determine whether Calidris paramelanotos is a distinct species or a hybrid, DNA sequences from the mitochondrial cytochrome-b gene were obtained from it, as well as from C. ferruginea and C. melanotos. The sequences of the first two taxa were identical whereas that of C. melanotos differed by 9%. It is argued that C. paramelanotos is a hybrid taxon with C. ferruginea constituting the maternal parent. This conclusion, combined with comparisons of protein allozyme variation effectively rule out all but one of the crosses postulated for its hybrid origin--C. ferruginea × C. melanotos.
