Frequently, I make the mistake of getting too close to a Tall Bird nest, mostly by stumbling upon it in an unexplored area. I haven't been successful at defeating them, so I run.
It seems to me that Tall Birds chase you farther than any of the other mobs I've encountered.
I've been able to put some distance between us by zig-zagging which makes it stop to attack every time you change directions, and allowing you to run farther away.
Is there any other way to get them to stop chasing you? Anything you can drop? Or a biome they won't enter? Or, any other stratgey?
