If anyone's curious how to get the bird to fly away:

I found guides about having to run across the map and explore every nook and cranny. Turns out it is way easier than that.
All you gotta do is: Get to the red stone next to the event. Run up the tree. Get knocked back by the bird. Kill yourself using liquid escape. Done.

It may even be easier than that, given it'd be odd you'd have to kill yourself, meaning you'd never be able to get it on hardcore. So maybe just a port is enough, but this method has been a very easy and fast way.

It's time based. I was fighting mobs. Killed one of those elite flying things. Went back to check. The bird might need to flap its wings when you get close first. Then the timer could be counting down before it despawns after some time.

Might be the player has to go further in the area before it triggers the bird to fly away.

Maybe. But seems kinda dumb to do that when what I said works.

Just because one option works doesn't mean there's not a better one (also as you said this won't work on Hardcore)

I haven't seen much that is reliable with the bird yet. The weirdest thing was that I had seen it move away and got the ring and went back and the bird had actually come back.

The one regular thing seems to be if it sees you at least and screeches at you, or knocks you back. Then if you go and do a dungeon and come back, it usually isn't there. But usually is the key word there because it doesn't work every time.

Still not sure what gets it to move. I just usually see that it is gone after I get close and then go do a dungeon. I also tend to see it resting on pillar near another dungeon if the correct pillar is near a dungeon.

OP suggestion does not work for me. I just tried it exactly as stated 3 times, 3 deaths, bird still at nest. Thanks for all the fish.

All you have to do without a glitch is kill all the enemies on the map. When this is done, you will hear a big noise made by the flying Koara Kuri and you have a certain amount of time, I mean 1 minute, to get to the nest. It's best to kill the last monsters in the immediate vicinity of the nest. As long as there are still monsters on the map, the bird will protect its nest.

ps: oh, necro thread...
