Galapagos Finches or Darwin’s Finches are the type of species which Charles Darwin collected from the past. In fact, all in all there are 14 species of Darwin's finches; one in Coco's islands (400 miles from the north Island of Galapagos), and 13 species in the Galapagos Islands.
It was in the Galapagos Islands where the facts about the evolution of Darwin's Finches took place. Finches have the same features with the vampire finches since they as well suck blood from the other birds and they have also the same capability of the woodpeckers since they are able to search for foods on the woods. A lot of genetic analyst stated that 13 species of Darwin’s Finches are from the 30 flocks of birds that arrived in the Galapagos Island about many years ago.
Darwin's finches have sizes from ten to twenty centimeters. The shape and size of beaks on these finches vary, depending on what group of species they belong. The sizes and shapes of their beaks have changed and developed in time because of the supply of food sources. Large beak finches have the ability to get bigger seeds and nuts while those with smaller beak can catch smaller seeds for them to eat.
Aside from the seeds sizes, the finches may also differ from their food sources. Some of them eat leaves and insects while others prefer turtle ticks. Just as an example, vampire finches feed mostly on the seabirds' blood. Also, they are one of the most popular birds for their capability to utilize "tools" made from cactus spine and twigs as they consume their food. For them to feed on the larvae and insects, the woodpecker finches make use of these twigs to catch them under the cacti and trees.
Most of the time, ground finches have beaks to crush seeds for their food. The beaks of Vampire Finches are intended for sucking blood of other birds and some parasitic insects to feed themselves. Darwin finches also have another kind and that is the Tree Finches. Most of the time, these finches differ from other finches since their beaks has sharp designs which is intended for their food consumption.
The thirteen species of Darwin's finches in Galapagos Island are of genus Geospiza and are most likely arrived from South American bird species. The popularity that comes with caring the Darwin's finches has been widely acknowledged because of its unique account of evolution and its remarkable characteristics that distinguish them from the other bird species.
