Subspecies
Recent molecular-genetic research suggests that the Galapagos group consisting of present genus and Certhidea, Platyspiza and Geospiza, known collectively as "Darwin's finches", is allied to the tanagers (Thraupidae), being closest to Coereba, Tiaris and several Caribbean genera.
The following 3 subspecies are recognised:
productus Ridgway, 1894 - Fernandina (formerly Narborough I) and Isabela (Albemarle), in western Galapagos Is.
pallidus (Sclater & Salvin, 1870) - Santiago (James), Rábida (Jervis), Pinzón (Duncan), Baltra (Seymour), Santa Cruz (Indefatigabale) and Floreana (Charles), in central and southern Galapagos Is.
striatipecta (Swarth, 1931) - San Cristóbal (Chatham), in south-eastern Galapagos Is.
Similar Species
Similar to Mangrove Finch (Geospiza heliobates), but has larger bill, and has no streaking on underparts. Song is best way to differentiate them.
