Today I saw a little lump under one of the wings of my 8 years old female cockatiel. It's not visible from the outside so I don't know how long it's been there and I'm not sure if it's normal. She always had visible meat on that part of her wings if I remember correctly but I don't remember it being this lumpy thing.

The right wing (where the lump is)

And the left wing (nothing abnormal)

What's this thing? What am I supposed to do?

Thanks for your helps!

It looks like some type of cyst which is somewhat common for many cockatiels. I would have a vet look at it just to be on the safe side.
