Why does my cockatiel have bald spots under wings and grey feathers?

Updated On September 23rd, 2025

Pet's info: Bird | Unknown - Bird | Male | unneutered

My cockatiel has bald spots under his wings but they’re as big as a thumb nail. Also the feathers that rise up when he’s surprised have a hard grey coat over some of them. Also, i couldn’t take a picture of the bald spot under his wings or he would bite me and i could hurt him. And the 3rd picture is not my bird but a picture I got from the internet but his bald spot looks like that buts it’s a little smaller. His vocals are great and I try to let him out for a hour each day. So what’s up w/him?

The grey covering is a sheath that is on new or developing feathers. His skin looks irritated which may be due to parasites or infection. Ideally, he should be examined by your veterinarian or an experienced avian veterinarian. Clean and sanitize the cage, bowls, perches and toys. Discard anything that cannot be sanitized. Transition him to s commercial pelleted diet such as Harrison's, Lafeber, Exxact or Pretty Bird. You can supplement with a small amount of a fortified seed mix as well as with fresh vegetables and fruits.
