What is this bird nest for and why does it glow?

I've recently picked up Far Cry Primal and have been exploring the huge map. While running around, I found this bird nest that was shimmering and glowing like it's and interactable object in the game.

What is the point of it? It didn't give me the option to interact with it, yet it glows like any other object in the world you can interact with (the white shimmer is visible on the left side of the nest, it was difficult to capture a screenshot of it completely).

The nest can be found in the lower portion of the map. It was past a waterfall that you walk under. I've included a screenshot of the exact location on the world map below:

Also, setting the nest on fire did nothing, which is why it looks burnt in the picture, and the nest was empty when I found it.

Solution 1:

It's part of a quest to gather eagle feathers for one of your tribesmen, and becomes interactive at that time. You first need to progress in the game and trigger the quest.
