Galapagos Islands land birds


Darwin's finches are 14 different closely related species of finches Charles Darwin discovered on the Galapagos Islands.

Darwin's voyage on HMS Beagle, and the finches in particular, are known to have influenced his thinking so that he would later produce a basic theory of evolution by natural selection. Darwin reasoned that there had to be a common ancestor.

Later, much work was done by Peter and Rosemary Grant. The birds are all about the same size (10–20 cm). They mainly differ in the form of the bill. The bill is adapted to the food they eat. The birds are all brownish or black.

They have short rounded wings and a rounded tail that often appears cocked to one side. Most male finch mature to a solid black color, while the females mature to a drab grayish color.

Exceptions are made for the Vegetarian and Tree Finches the males never become completely black rather they have a black head, neck and upper breast. Warbler, Woodpecker and Mangrove Finches have more of an olive color.

 Darwin's finches look very similar; it is the variations in beak structure which set them apart.

As with the mockingbird, you may want to take a few finch pictures on several islands and compare them after you get back. In this case, you'll also want to take some shots in the different Vegetation Zones within the same island/ specifically on Santa Cruz. Remember to note down the frame numbers and respective locations. For any kind of success, you'll need a telephoto lens.
