Taxonomy
Three subspecies are currently recognized[1]:
- G. d. septentrionalis - Darwin and Wolf islands
- G. d. difficilis - Genovesa and Pinta islands
- G. d. debilirostris - Santiago, Isabela and Fernandina islands
The population from Genovesa has in the past been ascribed to subspecies acutirostris; then the Pinta population would belong to difficilis, seemingly together with all birds in the debilirostris group. It has been proposed to split this species into three along the borders described in this paragraph.
Habitat
Dry forests and dry shrubland.
