Debra and Craig Johnson of J-Birds have written a brief article here about Eclectus parrots. Lucy is a Solomon Island Eclectus.

The authors do not go into the phenomenon of the bird sitting on the edge of her cage screaming and laughing like a little girl being chased while her housemate is on the telephone.

They also don't talk about how the brats will fake an emergency screaming bout to bring their owners into the room double-quick, only to find the bird preening.
