The first five images of Large Ground-Finch (Geospiza magnirostris) on this page were taken during an August, 2010, visit to the Galapagos Islands. The first four shots were taken on Santa Cruz Island, while the 5th shot was on Tower Island. All five images were taken with a Canon EOS 1D Mark IV and a Sigma 50-500mm lens.

Darwin's finches (also known as the Galápagos Finches or as Geospizinae) are a group of 15 species of Passerine birds, now placed in the tanager family rather than the true finch family. They were first collected by Charles Darwin on the Galápagos Islands during the second voyage of the Beagle. Thirteen are found on the Galápagos Islands and one on Cocos Island. The birds are all about the same size (10–20 cm). The most important differences between species are in the size and shape of their beaks, and the beaks are highly adapted to different food sources.
