Darwins Finch
 |
|
| [Note Guidelines] Photographer's Note |
Another shot from the Galapagos Islands; this one is of one of Darwins famous finches. The beak of this little guy was the thing that stood out the most to me. The beaks of these birds have evolved to be larger in order to survive the harsh desert climate found on the Galapagos. In dry climates, plants tend to have larger, harder seeds. These seeds can only be opened by large beaks. It has been shown that during dry periods, finch populations will have slight increases in average beak size. The opposite is also true during wet periods. These birds are an excellent example of evolution in action.
Cheers. |

Hi Wes,
Good sharpness and detail.
Unfortunately a bit noise to detect.

Hi Wes,
It's a female Geospiza magnirostris.
