Well, seems your boy is overly excited today. they picture you posted is surely showing excitement.
The most easily excitable amazons are Yellow Napes and Blue fronts.
Males are harder to handle then Females. they dont tend to be touchy feely birds.
My male Dyh has bitten me 3 times in 16 years. All unprovoked,no warning and all left battle scars. If there is a hint of excitement, I will not offer my hand.

you might have to stick train him to keep you both safe while he is in his mood.

A seperate play area away from his cage to prevent cage aggression.

I will see if I can get someone who lives with several amazons to come on and help you, but I have to get ahold of her first......
