New cords as of the Shattering:
Nothern Barrens (47; 76)
You have to go up the hill inside the little hill area where the other two nests are.

to find it go to the blue raptor nest and there should be a hill north of you. go to the right and the north a bit till u can go up the hill. voila you got it.

If you are at the blue nest and looking West it is directly in front of you... there is a path up the hill to the right of the blue nest if you are still looking west.
