@gardencat I was really lucky with this one! He was at the top of a small tree, so was only around 12 metres above me, and I was only a few metres from the tree. When they are 30 metres up a large tree, I usually have to be a good 20 metres or more away from the tree as well. So while he was not in any way 'near' me, comparatively he was much closer than usual.
