I, too, have killed my fair share of those birds. I rarely do this though, as the blasted birds barely appear for me and as I'm trying to get four Max 5 Chocobos, I don't kill any. What really annoys me is that Choco Meteor attack, as if you're caught offguard, you could lose heh. I was hanging out in Kilika, catching Bolds, and I was neglecting my lvl 99 charavter's HP, as I knew no fiend there could be a threat. Anyway, was in a battle and the bird casted it before running off. They were down to 2000 each before that this does several 100 points of damage. Needless to say, sailors cowered in front of my words after that close shave...
