It is the rutting season and unfortunately, this year, several people have been attacked. The largest stags are gathering their hinds, so there is quite a lot of clashing of antlers and roaring. They are magnificent beasts. The one pictured above hasn't got a "harem". Maybe he's too old. It was a hot day and he was wallowing in a muddy area. There are fallow deer as well as red deer in the park, a few hundred altogether, roaming freely.
