Here are the animal and plant species that I am certain, or 99% certain, of that I have seen during our trip through the US. If you sense something is not quite right here, please tell me, I could be wrong.
Again, thanks a lot to National Geographic’s Field Guide to the Birds of North America, Frida, Raul, Rich, Ralph, Charlotte, Sandra and Google for helping me in determining the species.
