Deer growling and attacking - we don't know why!

I heard my old deer friend, Susie, make a sound I never heard from a deer before. I looked in the bushes where she was certain the "problem" was, but I could see nothing. Still a mystery, but I thought the whole scene and especially the sounds she made, were worth recording. We suspect that perhaps there was a snake in that part of the bushes. This is a place where her fawns love to hide out, so perhaps she was thinking of her fawns, but we really don't know.
BTW, sorry, but we misidentified the gland next to Susie's eye. It's actually called the preorbital gland.
