How do birds blow their noses/beaks?

They actually do sneeze and from my experience of being at the receiving end of one, they tend to have a small amount of mucus with them, so this is probably how they get rid of the dust they inhale.

From the research I have found, birds do not blow their beaks.Birds have no need to blow their beaks. The reason humans blow their noses is for reasons of sanitation and etiquette, more or less. Humans don't have to blow their noses ; they can just let the mucous run down their faces if they want.

Birds have secretions from their beaks, and the secretions can carry viruses, like Avian Flu.

I have seen birds sneeze, so the answer to that is a definite yes, and they do not use a handkerchief afterwards.

Happy Hunting !
