PUCK the budgie was credited by the Guinness book of records as having a vocabulary of
1728 words. It is only fairly recently  that budgies have been recognized as highly intelligent
and excellent communicators. In fact budgies are now said to be among the top
5 talking
parrots of the parrot species.
ALEX   the African grey parrot  was said to have a vocabulary of over 150 words. He was quite famous
for his intelligence and linguistic skills,. He was exceptional in that he apparently understood what he
was saying. i.e.. he was able to use words creatively in context.

He was said to understand the concepts of quantity (up to six) and quality ( he could distinguish 7
colours) in objects. Alex was said to understand the concepts of  " bigger:"  ,"smaller:,"same: :different"
and zero, There is every indication that he had the ability to reason and use  words creatively
Prudle was captured in Uganda in 1959. For many years, Prudle held the Guinness world record  as
the parrot with the biggest vocabulary . He was documented as having  a vocabulary of 800 words

African greys also imitate phones, microwaves ovens, answering machines, chain saws, other birds
and household appliances.
N'kisi is said to be capable  of actual conversations. He apparently uses language as a means  of
self expression. He has a vocabulary of  over 700 words. He can speak in grammatical sentences
apparently and can use language creatively in context. He apparently understands what he is saying
and uses language appropriately.
puck
Apparently Puck  the budgie was able to create sentences.. He was also apparently capable
of using language creatively in context to communicate  and understand the meaning of those
words in situations.

In an old Persian text dating  back to the 13th century the method that was advocated for teaching parrots how to talk  had to do with mirrors and pure illusion.
It  was clear that the author did not believe that parrots could ever understand  what they were saying. The method consisted in putting a mirror between the
trainer and the parrot and having the trainer utter the words he wanted the parrot to mimic. He believed that the parrot upon seeing his reflection in the mirror
would  believe that he is looking at another parrot , a speaking parrot, and thus would imitate all that the trainer is saying  behind the mirror.
Einstein
Einstein, a talking  Congo African Grey was hatched in California in
1987. He was donated to the zoo at the age of 5.. No one knows if
Einstein ia a male or female. Einstein is referred to as a female
although this parrot has never been sexed.  Since being at the
zoo,Einstein has taken to mimicking  the sounds of chimpanzees,
pigs, wolves, cats, roosters, dogs,penguins, tigers and so many
others.
African Grey Parrots however are known to be the best talking parrots ,  
Parrots in general have the ability  to mimic sounds they hear,whether it is the
human voice, dogs barking, microwave ovens, doorbells, etc... They have the
ability to mimic up to 2,000 different sounds. They  also seem to be able to
understand the use of many words they learn and often use them appropriately

Why do parrots talk?

Parrots talk because they can. It is physically possible for them to produce sounds that imitate
human speech.  Unlike the other birds, parrots have one syrinx which is similar to our larynx  and
this is largely what allows them to produce sounds. The syrinx is a
voice box situated between the
trachea and lungs of parrots and this along with their  tongues is what allows parrots to modulate
the sounds they produce. (see
http://www.scienceblog.com/cms/node/3946)

Why do parrots talk so much?

Like humans  parrots have forebrain  areas involved in the learning  and control of vocals and this
is not something that is found in other birds, It is also the main reason why parrots can be so
versatile in their vocalizations.  The sounds and calls produced by other birds are innate, i.e., baby
birds raised in isolation from others of their species will produce the sounds and calls typical of
their species even id they have never heard these songs or  calls. beforehand.  Similarly a cat will
meow regardless of whether he has ever heard a meow .  A cat however will never meow in a new
way. A cat does not have the ability  to show great versatility in meowing. Just as most birds' calls
and songs are innate, they cannot sing or call in new ways or produce sounds that are atypical of
their species..

Undoubtedly, parrots do have calls typical of their species, however they also have the ability to
produce an extraordinary range of new sounds/ Parrots can mimic the human voice, phones,
doorbells, chainsaws, alarms, their mate, "accents" of other parrot flock, the call of their mates  
other bird species etc...Parrots can learn new sounds and can produce them very faithfully. One can
assume that they do so for many reasons. It can be to attract a mate, ward off predators, establish a
rapport with another flock, or purely out of "mischief".
Do parrots really "talk"

Parrots can imitate cats,i.e, parrots can imitate a cat's meow.  However strictly
speaking parrots do not meow. Cat owners know that their cats' meows all
sound pretty much the same but in context the meows all have different
meanings. A cat's meow can mean that he's hungry, or that he wants to go
outside, or maybe even nothing at all depending. A parrot owner know that
their parrots'  "meows" very probably do not mean anything. A parrot imitating a
cat's meow is not meowing. Meowing has no use for a parrot even though it
can be very amusing for us to hear.

Parrots can imitate human speech but does
that mean that they can speak?

It is sometimes said that animals do not talk because they  lack the mental
capacity. And this  means: "they do not think, and  that is why they do not
talk." But---they simply do not talk. Or  to put it better: they do not use
language---if we except the most  primitive forms of language.---  
Commanding, questioning, recounting,  chatting, are as much a part of our
natural history as walking,  eating, drinking, playing.
( Wittgenstein , PI 25)

The development of intelligence in animals is not related to speech. If we
teach "language" to animals to educate them in things that they already  know
what have we accomplished.?  A parrot would necessarily have a concept of
quantity even if  it cannot articulate it.  A parrot knows the difference between
one seed and many seeds. Similarly, a parrots would have a concept of quality
in objects and their marked preference for hard seeds makes that clear.  A
parrot has a concept of time , and cause and effect etc... Their very survival
depends on it. The development of intelligence in parrots is not related to
language. A parrot  that does not or will not speak is as intelligent as a parrot
that does  "speak."

In the wild, parrots have a wide range of calls and sounds but they do not  
"speak".,i.e., they do not imitate human speech.  A captive parrot that imitates
human speech is not "speaking".. Parrots do not speak, or meow, or bark.
None of these vocalizations have any uses for the parrot.

We can certainly teach basic vocabularies to our pet parrot and even get them
to associate words with  meanings .We can certainly get parrots to "use
language" in a limited context and they will willingly do so quite often. For
parrot this may well be a new dialect they pick up to bond with their human
"flocks".
But parrots do bot use language. Language has little use for a parrot even
though it is very amusing for us to hear them. Parrots will never use language
to explain, to describe, to chat, to tell a story  etc....it is not part of their "culture".
Captive parrots do use words in their domestic setting to communicate some
things but often  their vocalizations really do not mean anything.
