Systematics[edit]

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

Evolution[edit]

This bird is one of the extant parental species of one of the Spinus/Carduelis three evolutive North American radiation which extended to South America after closing of Panama Istmus.[3] That of atrata, crassirostris, spinescens, cucullata, yarrelli, magellanica, olivacea, xanthogastra and barbata and a few others.
