I believe I said both. Let me clarify.
1. When your talking about things that appear to be extremely similar it is hard to translate the biblical term "kind". I would have to investigate all of the creatures you mention to determine what can't breed with what, what could breed but doesn't, and what can and does breed.
2. However I was willing to consider different types of finches as being different kinds just for the sake of argument. What you need to show in that case is that one type of finches evolved into a different type.
Simply claiming that different groups of finches exist is not proof that one group evolved into another. Are you keeping up with all the terms involved? I can't. We got types, groups, species, populations, finches, kinds, primates, mammals, vertebrates, etc....ad nausium. Its becoming unmanageable.
