I didn't get an exact head count as they disappeared pretty quickly. But there were a fair number. Earlier in the day I saw five Red Deer on the Mt Clear Campground Road but didn't get a photo. Quite possibly the same animals as there is not a huge distance between the two sightings.
They were for many years restricted to the lower end of Naas Valley. Sad to see they are now much more widespread, joining the Sambar and Fallow Deer already present through this area.
