Backlog Conquering - RiME - Part 3 - 2 Windmills, A Bird, And Lot’s Of Water

In part 3 of playing RiME on PS4, i feel like i continue to make good progress, but i still don't have much of a clue what's going on. Plus, in this video, i'm a little confused about the giant bird and what we're doing to subdue it. surely, if this bird has always been an issue, the fact it still exists should be worrying. especially when we're seeming painting the sky with storms. Is this a permanent thing? is this a "weapon" that was made and never used before? it brings a weird tone to the story of the game.
