Pinzón terrestre mediano

could be some kind of grosbeak maybe...

I think 99% is enough ;-)... I get since many years regular news from the Swiss Friends of the Galapagos about your work and did already donations, specially for the leather boots for the dogs...

Yes, the variability is great and I am only 99% certain that it is G. fortis. Note that also the finches get confused at times; some of them hybridize. - Join facebook.com/darwinfoundation to learn more about our work.

OK, nice try ;-)... Thanks for clarification. A very short moment I also thought of Fortis, but I was really overhelmed by the great variabilties of different finches.

Muy buena esta también! Estoy casi seguro que se trata de G. fortis. Comparan con la foto en la Darwin Foundation database.

Oneof the famous Darwin's Finches! I hope that I have the right one...
