Weird "lump" on wings?

My apologies, I couldn't tell exactly where the bump was from the picture. Hope I didn't cause any alarm.

No worries, that's what we're hear for It's actually really nice when we know the answer rather then only being able to say contact a vet. A lot of my friends brought Rosie's joint to my attention too, and random people when I bring her places so your not the only one who thought it was bad.

My friend was like "omg it looks bad" and for me it was pretty normal as soon as she bathed and it was visible. Then I was stressed

@Mudkips, my bad that Lou has some kind of ADHD and she can't sit in one place so I can't make a proper photo ^^

Hello I just discovered the bumps on my cockatiel and have been really upset. He is almost 19 years old and he recently lost the ability to walk so he has been letting me touch him more. I think it's just what you said above about elbow joints like on your pretty pink bird. Thank you!
