The adult male is completely black, while females and juveniles have a design similar to the females of the other Darwin´s finches, though more ochraceous-brownish than grayish. It has a distinctive beak, as it is long, thin, and curved, with little resemblance to other Darwin´s finches. Although it is a terrestrial species, it can be found in all habitats present on the island. Monotypic.
