Speciation in Golden-Plovers, Pluvialis dominica and P. fulva: Evidence from the Breeding Grounds
Connors PG, McCaffery BJ, Maron JL. 1993. Speciation in Golden-Plovers, Pluvialis dominica and P. fulva: Evidence from the Breeding Grounds. The Auk. 110(1):9-20
Two forms of golden-plover have long been considered subspecies, Pluvialis dominica dominica and P. d. fulva. Prior studies have shown differences between forms in breeding distributions, wintering distributions, plumage, morphology, molt, and maturation schedules. We report clear and consistent differences in breeding vocalizations and nesting habitat, and strict assortative mating in areas of sympatry in western Alaska. These results indicate a greater degree of differentiation between the forms than was previously appreciated. They are appropriately treated as separate species and should be referred to under the names Pluvialis dominica, for the American Golden-Plover, and Pluvialis fulva, for the Pacific Golden-Plover.
