Buntings and New World Sparrows (Emberizidae)

Swamp Sparrow (Melospiza georgiana) - HBW 16, p. 549

French: Bruant des marais German: Sumpfammer Spanish: Chingolo Pantanero

Taxonomy: Fringilla georgiana Latham, 1790, interior of Georgia, USA.
Genus generally considered to be closely related to Passerella and Zonotrichia; unpublished molecular studies suggest close relationship with Xenospiza and some of the grassland sparrows (Passerculus, some Ammodramus, Pooecetes and Oriturus). Race nigrescens rather distinctive, and apparently differs from others in ecology, migratory behaviour and nesting biology; further study required. Differences between ericrypta and nominate race slight. Three subspecies currently recognized.
