Formerly listed as L. leucopterus. Closely related to L. argentatus, and in past sometimes treated as conspecific. Taxonomic position of form kumlieni currently uncertain: sometimes considered a separate species, as birds with grey wingtips occur alongside those with white wingtips in Nearctic; on the other hand, sometimes regarded as a glaucoides × L. thayeri hybrid. E–W cline apparent, from pale glaucoides to slightly darker kumlieni to darker L. thayeri. Increasing tendency to lump L. thayeri with L. glaucoides refuted, however, as such treatment would make the species undiagnosable; yet kumlieni hybridizes with L. thayeri, and may be closer to latter than to L. g. glaucoides. Two subspecies provisionally recognized.
