If there are dead bird bodies, does that mean if he's talked with a bird before, it might be gone, or do more than one birds now reside in the same (possibly wrong) body?
That's correct. If bird A is now claiming it's in the body of bird B and has seen its own body (A) dead, then there is a dead bird B. You're only dealing with one bird spirit per bird body.
Were there human people who were also left behind/dead at the same time as the birds?
No! Just the birbs.
Has that kind of experiment only happened in Bonaccorso's quarters?
In fairness, these birds would only know about their limited personal experiences, so they'd answer 'yes.' But it's a 'yes' otherwise anyway.
