Traditionally treated as conspecific with P. sandwichensis and P. rostratus, and often also with P. sanctorum, but all differ in morphology and plumage and, to some extent, in ecology; separation at species level supported by recent genetic findings. Two additional proposed races from Baja California: anulus, described from Scammon’s Lagoon (Guerrero Negro), is treated as a synonym of beldingi, and magdalenae, from North Estero (in Bahía Magdalena), is synonymized with nominate. Two subspecies currently recognized.
