The above video shows a rough edit of some camera tests we have done in the Valley of Rocks in Lynton and in the Cheddar Gorge near Bristol.

Feral goats are not very shy and somehow probably genetically used to humans for they were one of the first domestic animals in the neolithic age.
It tooks about 3 days to gather this material. Neither being disguised, camouflaged nor prentending to be goats ourselves, just studying their movements in detail with a camera on a tripod.
