Buntings and New World Sparrows (Emberizidae)

Bell's Sparrow (Artemisiospiza belli) - HBW 16, p. 565

French: Bruant de Bell German: Beifußammer Spanish: Chingolo de Bell
Other common names: Bell’s Sage Sparrow; Saltbush Sparrow (canescens); San Clemente Sage Sparrow (clementeae)

Taxonomy: Emberiza belli Cassin, 1850, near Sonoma, California, USA.
Until recently placed in genus Amphispiza, and considered conspecific with A. nevadensis, but recent molecular work indicates that the two are, instead, members of a well-resolved clade of “grassland” sparrows that includes genera Pooecetes, Oriturus, Passerculus, Ammodramus (in part), Melospiza and Xenospiza. Present genus newly erected to accommodate these two species. Race canescens, closely similar in appearance to A. nevadensis and possibly hybridizing with it where ranges meet, has been thought perhaps to represent.. View all taxonomy...

Taxonomy: Emberiza belli Cassin, 1850, near Sonoma, California, USA.
Until recently placed in genus Amphispiza, and considered conspecific with A. nevadensis, but recent molecular work indicates that the two are, instead, members of a well-resolved clade of “grassland” sparrows that includes genera Pooecetes, Oriturus, Passerculus, Ammodramus (in part), Melospiza and Xenospiza. Present genus newly erected to accommodate these two species. Race canescens, closely similar in appearance to A. nevadensis and possibly hybridizing with it where ranges meet, has been thought perhaps to represent a separate species; further research required. Race cinerea intergrades with nominate in NC Baja California. Race clementeae should perhaps be subsumed into nominate. Four subspecies provisionally recognized.

Subspecies and Distribution:

  • belli (Cassin, 1850) - California on W slopes of C Sierra Nevada (S to Mariposa County) and coastal ranges (from Trinity County and Shasta County) S to extreme NW Mexico (NW Baja California S to c. 29° N).
  • clementeae (Ridgway, 1898) - San Clemente I, off SW California.
  • cinerea (C. H. Townsend, 1890) - C Baja California (S to 26° N).
  • canescens (Grinnell, 1905) - breeds in interior SC California (S San Joaquin Valley, Inyo region, and S & W edges of Mojave Desert) and adjacent W Nevada; non-breeding also W to SW California, E to S Nevada and W Arizona, and S to NE Baja California.
