Mangrove Finch (Camarhynchus heliobates) [XC18026]
     by id from Playa Negra, Isabela, Galapagos, Ecuador (song)

Subspecies
No 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.

Similar Species
Similar to Woodpecker Finch (Geospiza pallida), but has smaller bill, some faint streaking on underparts and is slightly browner. Woodpecker Finch (Geospiza pallida) are not known to get black hoods. Song is best way to differentiate them.
