Storm you should look back on these posts, i made pretty detailed feedback on that fight, as i also had some trouble and was pretty confused at first on just how to beat them, let me see if i can dig that up for you.
-------------------------------------------------------------------------
I decided to give up trying to do caves and the forest, and carry on with the storyline, i am currently doing the Simurg (Shouldnt these be called Simurgh? Thats what the bird is called in FFXI and other final fantasy)
I just paused it while doing this fight, it dont seem too difficult at the moment, i do think the camera is a bit too far away though, apart from that this new boss fight looks good.
Oh they do Angel Whisper!?? Nice move by them, you can tell these are protecting the Pheonix alright.
Ok these are quite difficult lol, i was just about to finish them off with a Hyper Jump i think(must have to kill them all at same time so they dont angel whisper) but then it crashed again
Tried this again with a better strategy, managed to get down to 1 bird, and used Angermax to finish it off, then they all used Submit, was a pretty awesome fight! Good job on this

This fight, its a matter of keeping them poisoned, and your characters hasted, wall etc.
You can tell when a bird is dead (although its still on the screen) as you can no longer target it, its like a race to see how many birds you can kill before they start using angel whisper.
I tried this fight, and it took a while, but i managed to do a string of moves, then i could only target one bird, the angermax was very good on this, so my recommendation is to use your summons, enemy skills and magic which hit all the birds, then when they start to die, finish with limit breaks, as then the birds will not be able to raise each other, when the battle sees that all birds are supposed to be dead, they will all use a 'Submit move' which is basically them attacking and killing themselves off.
A fun fight, but if you really think that is hard, wait til you get to the train part lol.
Also the comment about the grand horn, if you are so bad at the mini game that you need to fight the grand horn, im pretty sure you fail the mission, and you wont be allowed to get pheonix til later on in bone village, Gjoerulv added a boss for all the summons you can pick up along the way (except ramuh).
Also do not waste your hero drinks, they are very rare (unless you cheat with W-Item) and they will become so valuable later in fights like the battle arena (for final attack materia) and other extremely hard fights like the Knights of the Round boss and the weapons.
