I'm not sure where to go with this one, G-Man. I mean, the most obvious would be that the froggies have it in for American (maybe still angry about that whole "freedom fries" thing), but I'm leaning towards a rather more insidious threat. I mean, how often do you operate at an AGL low enough to ingest amphibians? Based on that unlikely flight profile, I postulate that the little buggers are out to get us: they are lurking in the weeds like little VC, looking for an opportunity to slip unnoticed under a cowl where they wait for a critical flight phase to throw themselves into our turbines. Yup, they're like little jihadi's, ready to go to frog heaven and 72 virgins if they can only take down that chopper.
Careful in the deadman's curve, boys, that's frog country.
