Cactus finches are native to the Galapagos Islands. So they're found in subtropical and tropical forests and shrubland. Scientifically, they used to groupedwith American sparrows and buntings into the Emberizidae family. But they now are grouped with tanagers into the Thraupidae family.
Their specific scientific nameinvolves the genus to which they belong. It's the equivalent of a person's last name. It also involves the species, which somewhat may be thought of as a loose first name. For example, the species name is always Geospiza. But there are six sets of species names. The large cactus finch is Geospiza conirostris, the sharp beaked ground finch Geospiza difficilis,* the medium ground finch Geospiza fortis, the small ground finch Geospiza fuliginosa, the large ground finch Geospiza magnirostris, and the common cactus finch Geospiza scandens.
There's a subcategory that's called the vampire finch [Geospiza difficilis septentrionalis].

do all finches have the same beak.
how finches use their beaks
The Galápagos Islands had finches that once shared a common ancestry. Darwin found that finches on one island had, over many generations, developed and adapted in differing ways to finches from other islands.
Well... I personally think that cactus finches eat cactuses because in some images on the web, if you type in cactus finches, some will have a picture of a cactus finch eating bits of a cactus.
The shape of the Galapagos finches' beaks is adapted to the type of food available in their environment. Different beak shapes allow the finches to efficiently exploit different food sources such as seeds, insects, or cactus flowers. This adaptation helps the finches survive and thrive in their specific habitat.
