Description
Like the other members of its genus, the medium ground finch is strongly sexually dimorphic; the female's plumage is brown and streaky, while male's is solid black, with white tips to the undertail coverts. The bird measures 12.5 cm (4.9 in) in length—which falls between the lengths of the small and large ground finches. The bill of this species is quite variable in size, though the length of the upper mandible is always greater than the depth of the bill at its base. The wing shape, on average, seems to change with ecological shifts. Different selective pressures act on the wing shape of the finches, such as natural and sexual selection. The males have shorter, rounder wings, which help with maneuvering around a female during sexual displays.

Feeding Habits
Medium Ground Finch primarily consumes seeds and occasionally dines on flowers, buds, young leaves, and insects. They forage on the ground or in low vegetation, with unique beak adaptations for diverse diets.
Habitat
Medium Ground Finch typically inhabits arid to semi-arid environments, thriving in various island terrains across the Galápagos archipelago. These birds are versatile, residing in areas from scrublands to forest peripheries. While medium Ground Finch can be found at all elevations, they show a preference for lower, drier zones and are more frequently encountered in transition areas between ecosystems. The species adapts seasonally, with an increased presence in humid highlands during non-breeding periods.
