As I cannot add images to comments, this guide is intended to further detail the location recommended by Gillanaut. The nest in the first map can work for this solution. It did not pop when I landed on it, but worked when I headbutted it
. The nest is located at the tip of a rock extension that's connected to the snowy peaks. Here is an image of the location from above, with the relevant rock extension being the one my bird is facing.
