I thought i'd go ahead and search for some of the best hotspots for certain animals as there are specific places I've found which do spawn more regularly than normal. I've only made a start, but i was hoping everyone would chip in and help out with it when they get some time.
Here's the Hunting Hotspot map.
On the imap is the location i found to spawn cougars pretty regularly. They seem to spawn best in the early mornings and during the day. I haven't seen any at night anyway. Best thing to do is walk up and down the cliff until they appear, but they do appear specifically in the area i spotted on the map.
After a long search along the river banks, i found a really good spot which spawned me beaver after beaver by leaving the area slightly and returning almost straight away to find a new one replaced the one before. on the hilly part between the few trees is where they spawn.
I found these pretty annoying to find, i looked in Still Water Creek, no luck. So i moved around towards Tanners Span where the river can be crossed on a horse from Hennigan's stead. I found three in the same place on a few occasions. Also there is a guy there with a skinning challenge which requires you to lay bait and skin 2 boar for him.
Anyway, i've made a start, if anyone would like to suggest any other decent places and put the on the imap, it would be appreciated.
