The man was shot in front of his parrot, who repeated, in the victim's voice, "Don't [expletive} shoot!" over and over again, later. The man's wife was convicted of the crime. Possession of the parrot went to his ex-wife.
If the bird had gone to a pet shop or the public, instead of to the ex-wife, one might wonder if the bird would have been heeded.
(Of course, I'm sure there was more to the case than what the bird said.)
.....a little bird told me......
Another article I read said the parrot did not give evidence to a jury.
A young man had a female parrot with a less-than-desirable vocabulary. A friend suggested that he leave the female parrot, for a time, with a local
Catholic priest who had two trained male parrots in the hope that the exposure would improve her vocabulary. The young man contacted the priest and
the priest agreed to the arrangement.
When the young man arrived with his parrot, he noticed that the two male parrots, Peter and Paul, were in their spacious cage busily reciting a rosary. The very first thing his parrot proclaimed quite loudly, and with considerable zest, was, "root a toot, toot, I'm a prostitute". Peter immediately exclaimed to to Paul, "Put away the beads, Paul. Our prayers have been answered!"
