The optional objective is not to touch the ground or water, thats easy, but then there is collect 3 feathers. I can only collect 2 of em. There is 2 more on the map but the map is blocked off and I can't go to that area. How the heck do you get the third feather?

The third feather doesn't show up on your map, you have to discover it yourself. It's NW of the hiding place you eagle fall into at end of main objectives. Climb up dead tree, and it's a short fee-run to get to it. Remember to use eagle vision to spot the feather easier.
if you climb up a tree and go through them as you travel towards the next marker you should discover the 3rd feather, thats what i did after i found out i couldnt get to the other ones that showed on the map
