Buntings and New World Sparrows (Emberizidae)

Bachman's Sparrow (Peucaea aestivalis) - HBW 16, p. 568

French: Bruant des pinèdes German: Bachmanammer Spanish: Chingolo de Bachman
Other common names: Pine Woods Sparrow

Taxonomy: Fringilla aestivalis M. H. C. Lichtenstein, 1823, Georgia, USA.
Formerly placed in Aimophila, but molecular-genetic studies indicate that such treatment would make that genus polyphyletic. Closely related to P. cassinii and P. botterii, all having aerial song displays; molecular analyses suggest that this group is close to a clade consisting of P. ruficauda, P. humeralis, P. mystacalis, P. sumichrasti and P. carpalis. Geographical variation largely clinal, and races weakly differentiated. Three subspecies recognized.
