What is the correct name for a flock of parrots?

A group of parrots is called a pandemonium, company, or flock.

A flock of parrots. Ignore those ridiculous group nouns that have been invented for everything - including rhinoceroses which are solitary. These group nouns (apart from a small number like school of whales) only occur in books of lists, dictionaries, crossword puzzles and trivia quizzes. They don't occur in real life.

Also known as a "Company of Parrots."

It should be a repetition of parrots

A shoulder of parrots.

A PANDEMONIUM or COMPANY* of parrots.

Baloo... I thought whales lived in pods, and fish lived in schools.

I would stick with flock of parrots
I understand why the silly-name-everything people would call it a pandemonium: a flock of parrots could be incredibly noisy judging by the noise created by parakeets in the local petstore. Still, I couldn't bring myself to compare birds to demons. (pan=all; demon=just what it looks like--demon; ium=ending for a place, like auditor*ium; pandemonium=all demons together, a word currently used for "all hell broke loose" and general chaos)
