jevajeva:

The genus Spinus, containing mostly New World siskins and the American Goldfinch. These species were once included in Carduelis along with Old World goldfinches. 

The Black Headed Siskin (Spinus notata) is thought to be a “patriarch” species from which similar South American siskins radiated after the founder population crossed the Panama isthmus in the late Pliocene.
