Nostril Growth on 21 year old cockatiel fell off tonight.
my baby scruffy. (21 year old baby)
My cockatiel is about 21 years old, and over time has developed a growth on his left nostril. In the past month, it has grown a bit, but the bird has not shown any signs of discomfort. Tonight, the growth fell off, leaving what looks like a gaping hole where the nostril should be.
Even still, the bird does not appear to be in any pain or discomfort and is going about his normal activities.
I have attached a picture of what he looks like, which I took right after the growth fell off.
Is this life threatening? What signs should I look for that should cause me to worry?
