Hi Silvanus and Tanin,

Thank for your prompt reply. I handle it about an hour early in the morning and only a few minutes in the evening. Can't reallly tell whether it sneeze during other time of the day.

It has been sneezing like that for more then a few months which I just overlook it.

One good news is the it does not fluffed and listless on their perches. It is always swinging and playing rough. Eating well as well and no weight lost, so I guess it is still in good health.

Once again thank for the advices, I will monitor it condition and send him to the vet when time permit.
