The Mangrove Finch is a small bird endemic to the Galápagos. It searches mangrove leaf litter and dead wood for arthropods and nests high in trees.
It is about 14 cm long.
It forages in mixed mangroves, taking arthropods from leaf litter, dead wood, and red mangrove buds. It nests mainly in the outer canopy of black and white mangroves.
