The chamois proved to be very hard to approach. In both locations near camp where I was regularly seeing them it was very wide open tussock faces and they were nigh impossible to get to without them seeing me from afar. They have incredible eyesight and spot movement very well.
I did get one opportunity for a stalk on a chamois that was bedded facing downhill and I was able to use a large boudler as cover and approach from above. In spite of the noise of moving through the tussock I popped out from behind the boulder to see it standing and looking back at me. It was a longer shot for me, around 30-35m and I missed. It ran off to stand and look at me from about 100m and watched me leave and head back up the slope to my backpack. That was the only chance I had for the trip. They are a tough proposition with a trad bow. There are a lot of factors that need to come into alignment for success to come to bear. A rifleman would have shot multiples of each species this trip.
I enjoy the challenge though and when success does come it is a feeling of great accomplishment that makes it all worthwhile.
