My knowledge of real reindeer is slim. The whitetail deer which populates much of the American Midwest and Northeast — that is more familiar.
And whitetail deer are browsers. They love to nibble on bushes and trees. Perhaps they can stay more alert for enemies than when grazing on grasses.
My decorative deer appears to enjoy boxwood. No problem. It’s after hunting season in this area and he’s safe. And still. This year I was allowed to add a festive ribbon to his chest.
