This is the southernmost of the world's siskins. This an immature male showing trace of black cap.. Here I follow Clements, H&M, and IOC all of whom moved the New World Siskins from Carduelis to Spinus. HBW retains Carduelis but SACC places them in Sporagra instead, requiring a change to the specific epithet to barbata for gender agreement. For details on classification see SACC Proposal 488.
