The Genovesa Cactus Finch is restricted to Genovesa Island in the Galápagos. Its long, narrow bill is compressed from side to side, and the bird uses dry lowland scrub where prickly-pear cactus grows.
Males are mostly dark, with a pale buff area and a black wedge on the undertail. Females are browner and streaked below. Both sexes have a long, narrow bill that appears flattened from the sides.
It uses dry lowland scrub and cactus-rich sites, eating cactus fruit and flowers as well as insects. Seeds are reported only as a possibility. Breeding is linked to rainfall, so timing and success can vary with rain.
An extinction-risk assessment has not been added yet.
