I am an avid watcher of them on You Tube - Especially Mr Max and Pebbles.
Do they normally have temper tantrums? Is it just rescue birds?
Pebbles in particularly goes into one in a spectacular manner and is a real potty mouth. She came from an abusive home and was pretty much passed around a lot, but is now (thank God) in a really caring home with a very patient man!
They are certainly intelligent birds. Mr Max usually throws a temper tantrum when he sees his carrier (vet time!) and has been seen patiently removing screws from his carrier!
