An extraordinary budgerigar called Puck is listed in the Guinness Book of World Records as the bird that has the largest vocabulary in the world – he knows 1,728 words. This is really amazing as there are people whose vocabulary isn’t that rich!
Puck was observed for a period of six months by 21 volunteers who watched the bird and wrote down everything he said during this time. Additional Guinness documentation on the parrot includes tape and video records.
A very interesting fact is that Puck didn’t simply mimic what he had heard but made his own phrases and whole sentences. He demonstrated his ability to use phrases that are appropriate for particular situations.
Unfortunately, Puck died when he was only five years old. He was first listed in the 1995-1998 Guinness Books, then disappeared from the editions from 1999 to 2002 and reappeared again in 2003 and 2004.
