This mob digs mistletoe. They have been through here many times and cannot reach the big parasite bouquets higher in the tree.
The bitter cold weather we experienced earlier this year crisped a lot of the outside and exposed mistletoe. This crumbles as it dries and falls to the ground where the goaties crawl around to gather underneath the trees.
The tallest goat, Blue Duck, can reach some as he stands on his toes.
