please check out the reviews on the frankenmuth vet if you are using that facility. I remember reading something about a female vet there. Absolute and important to have him vet checked. On the weird side, if there is no discharge and no other signs, he could be mimicking sounds...Grady learned that noise from his owner and he taught it to Louise... it is pretty specific and I have heard all. I now see another poster can see stuff around his nares, so not mimicking now, but you may still hear the noise when he is healthy...
but yeah he's definitely sick, not mimicking. i'm just trying not to panic.
I have friend that has rehomed cockatoo, 3 nights after she got him he developed this huge hacking cough in the middle of the night. she took the bird to the Emergency vet thinking he was very sick. they kept the bird over night, she called the next day to see how the bird was. the vet asked her to come in asap. she was huge panic thinking the bird didn't make thru the night. when she got there the vet asst brought the bird into the room. he was fine. the vet came and mimicked the hack cough, then bird did the same thing and the very end of the bird sound like it was choking you can the sound rescue inhaler being pushed. apparently the bird live with someone who had asthma. he still does it if he hears somebody breathing hard.First off welcome and great that you have this new bird. When reading your post i thought it could just be a habit until you mentioned the discharge and then the breathing worried me a bit. I actually just adopted 2 african grays yesterday and the previous owner had just passed this past week and he was very sick for years. Both these birds are coughing up a storm and sneezing etc etc. It is not real they obviously learned this behavior from him. It scared the bejesus out of me when we left and were barely on the road for 10 minutes when i heard this old man cough in my car. Of course there was no old gentleman it was the birds mimicking his behavior. My own blue and gold will sneeze and say MAMA SICK and then i am suppose to say God bless you. So this is my portion of help hopefully its nothing serious. Good luck and hope you get a vet that can solve this issue.
