parrot choanal papillae

[kme3388]

Has anyone else seen the inside of their parrots beak? My macaw was chewing up some wood, and I seen his choanal papillae. I had to google what it was. It looks like something that belongs in a horror movie. If anyone knows its purpose please do share.

If you Google choanal papillae bird there's a pretty good explanation of what their function is.

My google tells me it’s for respiratory (breathing), feeding, and making sounds depending on the website :-/

I had never heard of them. Strange looking structures! Almost like throat teeth.
