About

The medium ground finch is a species of bird in the family Thraupidae. It is endemic to the Galápagos Islands. Its primary natural habitat is tropical shrubland. One of Darwin's finches, the species was the first which scientists have observed evolving in real-time.

Fun Fact

Medium ground finches on the Galápagos were the key inspiration for Darwin's theory of natural selection, and scientists have documented their beak size evolving measurably in response to drought within just two years.
