Taxonomy:

Linaria (Leucosticte) tephrocotis

Swainson

, 1832,

near Carlton House, Saskatchewan, Canada

.

Often treated as conspecific with all of L. arctoa, L. atrata and L. australis; recent analysis of mitochondrial DNA indicates close genetic similarity among all four#R. Has hybridized with L. atrata. Nominate race and griseonucha intergrade in Alaska. Proposed race irvingi (described from Anaktuvuk Pass, in N Alaska) considered synonymous with nominate, and maxima (from Commander Is, off NE Russia) synonymized with griseonucha. Six subspecies recognized.
