They were the same species of bird, but depending on which of the Galapagos islands they lived on, they had different beaks. Some were short and powerful for cracking nuts on nut rich islands, and others were long and thin for pulling insects out of tree bark in insect infested islands.

The sad thing is, becasue of global tourism, they are dying out.
