The Inaccessible Finch lives on Inaccessible Island. Its three island subspecies differ in plumage, bill size, and foods.
Males of the nominate form are olive green above and pale olive gray below. The upland form fraseri is brighter green and more yellow, while dunnei has a larger bill.
The island forms eat grass seeds and plant fruits, and also take insects and other small animals. The source describes food differences alongside differences in bill size and shape.
