Shaking Leg - Is he okay?

[BirdDad]

This is my sister's 1 and a half year old (presumed) caique.
He does this every time he wakes up, for a few seconds up to maybe a minute sometimes. He also usually bobs his head like he's trying to regurgitate while doing that, I just haven't caught it on video.
Is this behaviour okay? I've tried searching it up but I can't find a single thing about it.
I'm trying to convince my sister to get him to a vet to confirm whether the behaviour is okay or if it's a sign of a problem. She doesn't take me seriously because he's always done it.
I'm hoping maybe others' opinions would get her to change her mind.

In his old home they used cat litter in his old cage and his cage was rusty. His toys were rusty too.
I think that if there is a problem, it is probably linked to that.

He otherwise seems okay. He doesn't act sick and he only does that when first waking up.

Any clue what it could be?

Is that the leg he sleeps on? Just looks like stretching to me. Especially because he's always done it and always does it at a specific time. That's the description of a behaviour.

Of course each bird is different but

1. all mine sleep on both legs ( or in a squashed bunch in a tight corner)
2. When they stretch a leg, quite common, they stretch the wing on that side AT THE SAME TIME
3. That looks more like a tremor than a stretch, I have not seen that among mine

On the other hand, he seems to recover from it quite quickly. It may be voluntary.

I wouldnt panic, but I would mention it at his next vet check

To me, it looks like he is using his leg as a focus for his regurgitation. Jingo used to "bite" his leg and then feed it when he was younger and horny.

Yea I watched it again. It looks like a stereotypy behaviour. A learned behaviour as a way of coping.

I agree. I was going to say the exact same thing.

 

[Akoni]

I agree with the others. He is obviously regurgitating as he shakes his leg. I wouldn't worry about it.

It does look as if he is trying to feed his foot. Continue to monitor it to make sure that something else is not going on.

Yes perhaps. But coping with what?. Is this bird stressed?

Not necessarily. If it was in the wild it would be feeding another bird. Lacking that he feeds his leg instead as a substitute. A way to cope with the situation.
