Systematics

This species is considered the extant "father" of the South American siskin radiation.[2]

Evolution

This bird is one of the extant parental species of one of the Spinus/Carduelis North American radiation which extended to South America after closing of the Isthmus of Panama .[3] The species S. atratus, S. crassirostris, S. spinescens, S. yarrelli, S. magellanicus, S. olivaceus, S. xanthogastrus, and S. barbatus are believed to have resulted from this radiation.

gollark: It's built-in.
gollark: It isn't actually that new.
gollark: Check out the new (optional, the existing one works fine) potatOS installer program: https://pastebin.com/bpzbskdk
gollark: You can, technically, run potatOS on paper.
gollark: It's probably possible to go way higher.
