Blue and gold macaw in distress

Two macaws live in my home; both given to us by people who could not care for them properly. The green wing, George, loves my husband. Up until now, Wonder, the blue and gold, loved me. Lots of human-birdy bonding in our home.
We went away for the week of Thanksgiving, left our big babies with the woman who usually cares for them when we are away. She reported to us that Wonder was fine for five days, then started going to the bottom of the cage, turning in circles, and refused to come out.
After 8 days away, they're back home. George is fine, but Wonder is not. He paces or leans back and forth, is constantly antsy, and tries to bite me if I get near him. He's nicer to my husband than ever, and has looked to him for attention. But overall seems very unhappy. He'll step up for me, but that's it. He can't seem to find a place for himself. He's free to come and go but has been hanging out in the bird room.
For many years now he's been my sweetheart. Now he treats me like a stranger. I am so worried about him.
Anyone have any experience with this situation?

I have not had this , but I have had birds mad at ne . All you can do is not force anything and let him be curious about you. Im sure eventually he will turn around.He sounds upset you are his flock and left 8 days.

Your not alone.i was away on vacation for about the same length of time at the end of October. I'm still dealing with some "neglected macaw behaviors".
For a few weeks after I returned home my mac was more beaky than usually and for the first few days he was very rough. He has also been loud, bordering on attention screaming at times. There have been a few instances where I get barrages of calls when I leave his sight. I can tell he felt neglected when I was away and his behavior reflects it.
I can completely see your B&G being an angry resentful macaw. I would keep an eye on him to make sure he isn't ill, but to me it sounds like he may be holding a grudge.

Usually pissey and/or clingy only lasts a few days.

Read that Sally Blanchard article on your bird does not hate you, if you haven't already. Maybe you're doing something different because you are reacting to your bird being piss-ey, and he's picking up on that? Stress maybe?

The more you get things back to the "normal routine" the quicker he will get back to normal. But yeah, they do sometimes hold grudges.

Maggie occasionally gets piss-ey with Sarah.

Her solution for that has always been to ignore her for the rest of the day when she's like that. Then "the bird" has to make the first move and apologize.

Sometimes "the silent treatment" works better than trying to kiss up to them.

After all, there's nothing a big mac craves more than attention.

"You want my attention? Are you gonna be nice?! Yes? That's my baby!"

So you might try that as well.
