I know I'm resurrecting an old thread here, but my Mustached Parrot seems to have just suffered a similar seizure and I'm wondering how the birds of other posters have coped since.
My 8yo MP had been enjoying out-of-cage time with me today, was frisky and didn't want to return to the cage but eventually did, and then things got bizarre.
He suddenly shot his head down in what appeared to be a fear response - I thought he was reacting to something on the fresh newspaper in the tray - slammed his beak into the floor grill, and appear to step down onto the grill, where he sat frozen for around 3 minutes. His eyes were (barely) active but the rest of him was locked up, not even responding when I rubbed his beak - which MPs typically don't like.
He gradually 'came back' to himself and gently rubbed my finger back with his beak, but then urgently wanted out of the cage. He refused to return to the cage or step up, until I removed a toilet roll I'd hung for them to chew, and then reluctantly went 'home'. He appears to be quite dazed.
I'm concerned as I've given him a string of beads to chew, but I'm not 100% confident of the coating of the beads. As I write this I realise I've also placed inside the cage an old favourite toy of kitchen scourers and large wooden beads that came with them from the previous family - clearly I'll remove this as well as the bead strings.
We don't have an avian vet in Cambodia (that I'm aware of) which is one of the reasons I've been reluctant to have birds here until this pair needed rehoming.
Any thoughts, advice?
