The bison on our ranch are 100% wild bison and, even though they may become accustomed to my presence, they rarely fail to remind me of this fact. A most recent example of bison wildness has been the virtual disappearance of the new bison mother and her calf. After I first managed to photograph the newborn and it's mother they both went into hiding and it wasn't until this morning to I managed to catch a glimpse of the pair on one of my surveillance cameras. Both mother and calf seem healthy.
