Fringilla pinus

A. Wilson

, 1810,

Bush-hill, near Philadelphia, Pennsylvania, USA

.

Has hybridized with Loxia curvirostra. Geographical variation largely clinal. Outlying southern race perplexus presumed to hybridize with S. atriceps and has been speculated to be a subspecies of the latter#R, but recent detailed morphological#R and molecular#R studies strongly suggest that the grey-plumaged, weakly streaked perplexus is distinct from both S. spinus and S. atriceps, probably meriting species status; further analyses needed. Three subspecies recognized.
