Why is my cockatiel's nostril clogged? Is it serious? What to do?

Updated on September 23rd, 2025

About two days ago I noticed that on my cockatiel the nares on his left side is kind of closing up. It isn't inflamed or bruised, nor is there any discharge. His other nostril is just fine. What could this be? Is it anything serious? What can I do about it?

Thank you for using Petco Pet Education Center, formerly Petcoach! Cockatiels occasionally can form rhinoliths, which are small accumulations of debris and mineral. These are harmless but can clog the nares and result in trouble breathing. They can be carefully removed by a veterinarian.
Other causes can be a fungal or bacterial infection which can be treated by antibiotics prescribed by your vet. I hope this helps and am happy to look at any photos or answer any questions you may have!
