Classification

There are 15 species of finches on the Galapagos Islands. Each one is classified by the Adaptation of their beaks.

Domain: Eukarya

                  Kingdom: Animalia   

                                    Phylum: Chordata

                                                  Class: Aves

                                                             Order: Passeriformas

                                                                        Family: Thraupidea

                                                                                     Genus: Geospiza

                                                                                                 Species: G. difficilis septentrionalis

Kingdom: Animalia
The Kingdom Animalia is classified by eukaryotic multicellular organisms. Most can move independently and all are heterotrophs. Most embryos pass through the blastula stage, which is exclusive to animals.

Phylum: ChordataAll chordates have a notochord, pharyngeal slits, which are like gills, a dorsal nerve chord, connecting the brain to other muscles, and a post-anal tail, at some point in their life, even if it is only in their embryonic state.

Class: Aves
The Aves include birds, which have the unique characteristic of flight. To be able to fly birds have a one-way breathing system, light hollow bones, strong muscles for flying and feathers.

Order: Passeriformas
The Paseriformas, or perching birds, are the most diverse order of birds. The male and females differ in appearance. During breeding season they live in pairs and can become territorial and aggressive.

Genus: Geospiza
All species in the Geospiza genus live on the Galapagos Islands. They are most commonly known as "Darwins Finches".

Family: Thraupidea
Thraupidea, or tanangers members are non migratory. Most have short rounded wings and their beaks are determined by what they eat.

Species: G. difficilis septentrionalis
The species difficilis refers to the sharp-beaked ground finches. These finches Fernandina, Santiago, Pinta, Genovesa, Darwin and Wolf Island, whereas the vampire finch, septentrionalis can only be found on Darwin and Wolf Island.  The vampire finch is known because it will drink the blood of the seabirds
