Long-tailed finch
The long-tailed finch ("Poephila acuticauda") is a common species of estrildid finch found in Australia; also known as the blackheart finch, shaft-tail finch, Heck's grassfinch, Heck's grass finch, and Heck's finch. It is a predominantly fawn-coloured bird with a pale grey head and prominent black bib and eyes. It has an estimated global extent of occurrence of 1,000,000–10,000,000 km. It inhabits dry savannah habitats in Australia and adapts readily to aviculture. The IUCN has classified the species as being of least concern.
Small ground finch
Like all but one of the other Darwin's finches, the small ground finch is endemic to the Galápagos Islands. Abundant and widespread, it is found on every island in the archipelago except for the Genovesa, Wolf and Darwin islands. It is most common in arid coastal and transition areas, though it moves into the highlands following the breeding season.
