  2. Darwin's finches - Wikipedia

    en.wikipedia.org/wiki/Darwin's_finches

    The term "Darwin's finches" was first applied by Percy Lowe in 1936, and popularised in 1947 by David Lack in his book Darwin's Finches. [7] [8] Lack based his analysis on the large collection of museum specimens collected by the 1905–06 Galápagos expedition of the California Academy of Sciences, to whom Lack dedicated his 1947 book. The ...

  3. Camarhynchus - Wikipedia

    en.wikipedia.org/wiki/Camarhynchus

    All species of Camarhynchus are endemic to the Galápagos Islands, and together with related genera, they are collectively known as Darwin's finches. [1] Formerly classified in the bunting and American sparrow family Emberizidae , more recent molecular genetic studies have shown it to belong in the tanager family.

  4. Cocos finch - Wikipedia

    en.wikipedia.org/wiki/Cocos_finch

    The Cocos finch is a member of a group collectively known as Darwin's finches. [5] Although traditionally placed with the buntings and New World sparrows in the family Emberizidae, [6] molecular phylogenetic studies have shown that Darwin's finches are members of the subfamily Coerebinae within the tanager family Thraupidae.

    The finch species with smaller beaks struggled to find alternate seeds to eat. [10] The following two years suggested that natural selection could happen very rapidly. Because the smaller finch species could not eat the large seeds, they died off. Finches with larger beaks were able to eat the seeds and reproduce.

  6. Big Bird (finch) - Wikipedia

    en.wikipedia.org/wiki/Big_Bird_(finch)

    Big Bird, also known as the Big Bird lineage, is one of the species of Darwin's finches that is exclusively present on Daphne Major of the Galápagos Islands.It originated from a mixed-breed of the Española cactus finch (Geospiza conirostris) and the medium ground finch (Geospiza fortis) that immigrated to Daphne Major in 1981. [1]

    Large ground finch (Geospiza magnirostris)The Daphne Major finches are a group of Darwin's finches that inhabit Daphne Major island of the Galápagos.The common cactus finch (Geospiza scandens) and the medium ground finch (G. fortis) are the main species; [1] while the large ground finch (G. magnirostris) and the Española cactus finch (G. conirostris) are regular immigrants.

  8. Divergent evolution - Wikipedia

    en.wikipedia.org/wiki/Divergent_evolution

    One of the first recorded examples of divergent evolution is the case of Darwin's Finches. During Darwin's travels to the Galápagos Islands, he discovered several different species of finch, living on the different islands. Darwin observed that the finches had different beaks specialized for that species of finches' diet. [11]

  9. Large ground finch - Wikipedia

    en.wikipedia.org/wiki/Large_ground_finch

    The large ground finch weighs about 27-39 g, and its length ranges slightly 15-16 cm. [2] It is the largest species of Darwin's finch both in total size and size of beak. The feather and bill colors vary between males and females.
