I define it as the ability to "converse" with nature, as in read the frequencies abundant all around us. Magick is the ability to manipulate energies. So true to that definition i believe they could control weather, for instance. Like the fabled rain dance for instance. Where the shamans danced in a dry desert, and through the focus they had, imagining they were soaking wet, felt the raindrops on their skin before it was. Nature followed suit and it started to rain. But thats only a myth, dont know if anyone has proven it. What i am hinting at is our lost connection with nature, and skills that were normal then, might seem magickal to us. A book series that explains what i mean in better terms is called "the ringing cedars of russia"
