This 22 July 2019 video from the Natural History Museum in London, England says about itself:
Darwin’s finches from the Galápagos Islands
These finches were collected from the Galápagos Islands in 1835 by Charles Darwin and his colleagues during the second voyage of HMS Beagle (1831-1836) and are now part of the Natural History Museum‘s collections.
The different finch species on the islands are closely related to each other, but show wide variations in beak and body size and feeding behaviour.

Researchers found that Charles Darwin’s famous finches defy what has long been considered a key to evolutionary success: genetic diversity. The study of the finches of the Galapagos Islands could change the way conservation biologists think about species with naturally fragmented populations to understand their potential for extinction: here.
