You can see the finches in the Galapagos change annually. Thanks for the tip

That's not evolution. That's how they were designed.

You mean how they change color?

Beak size, and the species vary from island to island

Birds can manufacture melanins in their own bodies but can only acquire carotenoids through their food. Flamingos are a fine example of this; if they do not get the right molecules in their diet, which occur naturally in their wild diet, then they lose their stunning pink colouration. Early zoos had great problems keeping their flamingos coloured before this was understood.

Yeah... and they are all different species. In oder to see evolution.. you have to watch something change. You can't just look at two different birds and say they used to be the same. We have thousands of animals, all designed by God.
