Migratory ducks. I was thinking of your "regular birds".
All in all, still no reason to panic. It's happening in third world countries because of bad sanitation habits and not just falling from the sky.

Ah, so in post #10, when you wrote, "I should clarify, so far only domesticated poultry.", you were referring to 'domesticated migratory' ducks? Oxymoron alert.
And in post #9, when you wrote, "The geese are not currently carriers.", I guess you were implicitly excluding all of the geese from which HPAI H5N1 has been isolated, for example A/Bar-headed Goose/Qinghai/5/05 I mentioned in my earlier post?
Your bird-watcher's article lends nothing to my knowledge of H5N1. If that is your primary source of information then I can understand why you are uneducated about this disease.
