Longspurs and Snow Buntings: Phylogeny and biogeography of a high-latitude clade (Calcarius)
Using complete cytochrome b sequence data, we determined that the genus Calcarius, as presently recognized, is paraphyletic. Calcarius plus Plectrophenax form a highly supported clade composed of two subclades, a “snow bunting” clade comprised of Plectrophenax plus Calcarius mccownii (formerly in th...
