I'm sure they do not appear in travel guides, and I am positive that tourists haven't noticed them, but they are also part of the landscape of Barcelona: Argentine parrots are those little birds of the family of parakeets and cockatoos, that emit a peculiar noise.
They arrived in Barcelona more than 30 years ago, from South America and it looks that they have adapted well. It seems that at some time they were fashionable as pets, due to their green plumage with gray belly, and they were much cheaper than the typical parrots. But they turned out to be were unfriendly, they pecked their owners, they shrieked and....were keen on escaping! In other words, they wanted to live in freedom. So some of them escaped from their cages and now we have about 3,000 scattered in Barcelona, living with us.
Some look at them as a plague, but considering that there are about 250,000 pigeons in the city, I think they don'l give any hassle.
And besides, it is funny to think that the birds that have arrived from Argentina to Barcelona are parrots, which is an animal that has traditionally been used to describe someone who talks too much.
An irony, as well as Argentines (Argentine humans, that is) have a reputation for talking a lot. Of course it's a cliché ....isn't it?
