Not an aadvark
I'm not sure what the small black creatures are, they don't have ears like an aardvark. Help!
Guinea fowl. That one on the right is doing its best to throw you off- it has its head down, out of the frame, so its back end looks a lot like it could be a front end.
I can relate to your confusion here- a guinea fowl's body proportions seem to me to be more typical of a mammal than a bird, and the way their feathers seem to overlap so seamlessly is reminiscent of smooth fur.
