I was in a pet store today that carries parrots. A lady who has a grey came in and the owner was there so I asked them about screaming.

Both said it was uncommon for greys.

Apparently I was just lucky in knowing the couple of screamers that I've had contact with.

They are excellent talkers and mimickers.

So, based on those with far more experience than I, I was wrong.

Consider the grey.
