Medium Ground Finch
Geospiza fortis
One of 13 endemic species of Darwin finches in the Galapagos Islands.

Finches
There are 13 species of finch in the Galapagos, collectively known as ‘Darwin’s finches’. No other group of birds, indeed no other group of animals, has had such a profound impact on the development of human thought and our understanding of our place in our world, then these little brown and black birds.

When Charles Darwin visited the Galapagos in 1835, he collected specimens of the animals and plants that he encountered. Among these were the specimens of these finches. They were what we know to be one of the finest examples of adaptive radiation.

As Darwin gradually came to appreciate the significance of the finches, he could see clearly that all these little brown birds were essentially similar. This has since been confirmed by DNA testing. Each species was fitted into its own particular ecological niche: the small, medium and large seed eaters, the nectar eaters, the fruit and insect eaters and, most surprising of all, the tool-using bird.
All had developed from a common ancestor as a result of isolation and a relative lack of pressure from predators.

There are 13 species of Darwin’s finches. They are almost all identifiable by their beaks. Where this is not easy, identification can be by location: they tend to live on different islands, or inhabit different parts of the same island. In general, the males are dark brown or black, the females are mid-brown.

Medium Ground Finch
Geospiza fortis
Intermediate in size (12.5cm) between the Large and Small Ground Finches, it has a heavy bill but one that is much more pointed than the Large. The beak size varies considerably, even on the same island. The plumage is virtually identical to that of the Large Ground Finch. It tends to feed in flocks rather than individually. This species also feeds on the ectoparasites of tortoises and iguanas. Very well adapted to urban areas.

Hello Selen,
Very fine capture of this Finch unique to the
Galapagos. Excellent sharp details. The striking beak looks rather big, may be because of the angle of the shot? Thank you for a very interesting note too!
TFS and regards, Ulla

Another incredible good photo from you, Selen!
Perfect sharpness on the plumage, interesting composition and fantastic action subject. The sun on the bill makes it stand out in a 3D way.

Your note adds to the 5* rating.

Selen, this is remarkable! What a shot! Was he just trilling his song or producing an alarm call? Whatever, the photograph demonstrates the shape and the colour very well. Thereis fine detail on the feathers and the twig. Kind regards,
Bev :-)

Hello Selen,
Even though to look at this bird is very ordinary, the fact that you have taken a sharp close shot of one of these famous finches is in itself out of the ordinary.
In addition, you have superb lighting and BG set in a fine composition and the action of the open beak gives the shot character.
Thanks for sharing this one,
Best wishes, Ivan

Hi Selen

A great posting - I do not remember seeing any during my week in the Galapagos. The light on the feathers is great and makes the picture interesting and unusual.

Hi Selen

A very interesting but still cute capture!
The frontal POV here is outstanding nad the pose you've captured this fellow in is magnificent!
Good details on the plumage and nice OOF BG, too.

Bravo and TFS

Hello Selen,
You really have seen some mythical species recently and they are all beautiful! This is so interesting and I think that it is the first time that I have this opportunity to see this Sparrow :)! It is not everyday that one can travel in the Galapagos :) Details on the feathers and expression caught are priceless. Thanks for those much interesting notes.

Selen hazır elin değmişken Darwin ispinozlarının tüm türlerini fotoğrafla bence. Süper olur. belki de fotoğraflayıp bitirdin bile. Bu kuşlar türleşme sürecic açıklanmasında çok önemli ve klasikleşmiş objeler. Tümünün fotoğraflarını yan yana koyup incelemek isterdim. Eline sağlık. Mustafa
