Just recently Mercedes has started making a weird squeaking noise when my hand gets around him. He never has done this before. I've been bonding with him and so far he is a lot nicer and doesn't nip or bite. Sometimes though he does and before he does he makes this weird squeaking noise. Then he bites or nips at me.
That sound is a warning to you to back off it's as if Mercedes is saying "Not Now" and then the bite is further indication that he is not interested in socializing with you at that time.
Thanks for the info. Never heard that from Trickee nor Mercedes at first. I just thought that there was something bugging him. Like he was hurt in that area and didn't want me around it. He is doing better though and is in a molt losing his messed up tail feathers and growing in white on his head. I've just noticed that his eyes haven't changed a bit since I got him. They are still pitch black. Trickee's started changing after I got him to a grayish but his are just staying completely black.
