I know a lot of our birds are molting right now, is he? He looks like a sweetie who could use a good bath It's not as common in amazons but does he overpreen a bit? He is a very pretty bird his feathers just don't look as healthy right now, but like I said could just be from molting or needing a good shower/bath.

Good luck! It sounds like he is already starting to settle in. Let us know how it goes after quarantine when he is introduced to the rest of your flock.
