Urgent Creepy invaders

[DrLuv]

Hi I noticed a long skinny black bug crawl under my cockatiels feather. Long...?? 1/32 of an inch I guess...now Im putting it all together...her aggressive preening..especially at the wing joint. I just ordered 8 in 1 ultra care spray for cockatiels. My question is ...what is this? It didn't look like any pictures I could find except pigeon feather lice.
Thank you

I would take your sweetie to the vet and have her looked over. Those over the counter sprays scare me.

I use this, since I rescue wild birds and they have creepy crawlies...ok for parrots ...uses diamatious earth to kill the nasties..
