One of my birds (lady gouldian) has a strange lession under his wing. I saw him yesterday, he was a little sad, standing on one leg, and he seemed to have some blood on the wing. I took him to a little cage and he seemed better today, active and eating, but I took him to see what does he have under the wing, and he has like a tumor, with something in the middle. I don´t know if he was bitten by an insect or something.
I know that some pictures would be helpful. Unfortunatelly I haven´t learned to post pictures

Last time I sent Liz some pictures and she was so kind as to post them here. So, Liz, I will put you to work again, I am sorry. I hope you have time to do it. I am sending you two pictures right now to your mail.
Thank you!
