Itchy Peach Faced Lovebird, Blood on Feather
I have a 5 1/2 year old peach faced lovebird. He was hatched from my in-laws birds, so we've had him his entire life. He does not have a cage mate and has never laid eggs. He eats a mixed seed in his cage and these fruity pebble vitamin things. He also has a cuttle bone and calcium block. He eats off my plate a lot too, his favorites are eggs, turkey sausage, chicken, any kind of bean, bread, soymilk, tortilla chips, the accidental small amount of cheese... we never let him have avocado or soy sauce.
About a year and half or two years ago he started humping me or my fleece jacket when it was on a chair and this has since changed to him humping a towel on a towel bar (because I really don't like to be humped!). He also regurgitates on the towel (which he used to do in my ear, again, eww). He humps the towel several times a day.
He is still generally happy and flies around like normal (he has never been clipped). He has recently started acting VERY itchy. He lets me break his pin feathers that are on his head, but doesn't really let me get in there in any place he can reach with his beak. He has been so irritated, like something is getting him and he'll fly off my shoulder, do a circle in the air, land, then attacks his vent area.
For the past few days he has been asking me extra to come with him to the bathroom (where his towel is) and to his cage (where he has a bird house... similar to a nesting box).
Today he pulled out a small down feather that had some blood on it. I looked at his towel and noticed there was a little blood on that too. I flipped him over and there is a little dried blood on some feathers... he is not currently bleeding, as none of the blood is bright and wet. He is still irritated in his vent area though.
Do you know of reasons for this type of behavior? Thank you for your help! I love my lovebird (who is currently climbing on my glasses, asking me to follow him)!
