Complex and confused, with major upheaval in recent years concerning status of birds down Pacific coast of N America; at present classification of birds in this zone is tentative. Birds of Guadalupe I (Mexico) particularly complicated, with three distinct populations breeding, possibly all belonging to different races; extensive individual variation adds to confusion. Some races have been treated as separate species; race socorroensis has been included in O. monorhis; traditionally recognized subspecies beali now generally regarded as obsolete.

Complex and confused, with major upheaval in recent years concerning status of birds down Pacific coast of N America; at present classification of birds in this zone is tentative. Birds of Guadalupe I (Mexico) particularly complicated, with three distinct populations breeding, possibly all belonging to different races; extensive individual variation adds to confusion. Some races have been treated as separate species; race socorroensis has been included in O. monorhis; traditionally recognized subspecies beali now generally regarded as obsolete. O. monorhis sometimes considered a race of present species; these two may form superspecies with O. homochroa. Four subspecies currently recognized.
