Sister species of the Woodpecker Finch (Geospiza pallida) (Lamichhaney et al., 2015). Previously included in the genus Camarhynchus, but Lamichhaney et al. (2015) demonstrated that this genus is embedded in Geospiza. Adult males do not have a dark hood. It inhabits exclusively mangroves, which are naturally scarce in Galápagos, although non-breeding finches can occasionally be seen in the arid zone (Kleindorfer et al., 2022). It is affected by the Avian Vampire Fly (Philornis downsi) (Fessl et al., 2017), which likely reduces its reproductive success. There is an important captive breeding and reintroduction program in Isabela called the Mangrove Finch Project (Fessl et al., 2017; interpretation guide, pers. comm.). The estimated population is very low, fewer than 100 individuals (Kleindorfer et al., 2022; BirdLife International, 2023). Monotypic.

Geographic Distribution: Small breeding population north of Caleta Tagus, Isabela (Fessl et al., 2017). Vagrant individuals in Fernandina (Kleindorfer et al., 2022).
