Wheezing

I have been hearing Manzi wheezing a few times over the past two days. A parrot will act normal until they are very sick, at which time it is often too late to treat them with much success. My experience in working with animal health gives me a small amount of confidence that I have a slight advantage in detecting subtle differences, but I am still vigilant.
Anyway, after hearing Manzi wheeze, I would hold him close to my ear and every once in a while he would still make the wheezing noise. I wasn't sure whether he was imitating a wheezing noise, or his breathing was actually causing the wheezing noise. Not wanting to take any chances, I brought him to a neighbor with a stethoscope.

Luckily, living in the student housing at the largest agricultural university in the U.S. means there's an awful lot of veterinarians, many of them fellow graduate students who are more than happy to answer my questions and take a look at Manzi.

At first I was holding Manzi's head while the neighbor was listening with his stethoscope, but Manzi got fed up with that. So the neighbor suggested that I put the stethoscope on Manzi's back while he listened. That worked quite well and Manzi was just fine with that. Although afterward, the stethoscope was in the neighbor's hand nearby Manzi. Manzi looked at it for a couple minutes while we were talking and then he launched himself at it in an attempt to beat it up for it being forced on his chest and back against his will.

Conclusion: Manzi has a healthy heart beat and no unusual lung sound. If I continue to hear it or it gets worse, then I can bring him back anytime, but it is probably Manzi just imitating a noise.
