What is the name of a species of Dancing Bird in South America?

I actually happend to see a very interesting bird featured on a show. 3 - 4 male birds trying to flirt with a female bird by making really cute dance moves. They are very colourful and a little small. The one with the best moves gets to be with the female and the rest flies away with a gracious dance move again. They are from the Amazon........

Can any of u pls give me more info on this.... Name , Pic, etc.
They were so cute....... iam still looking for more details abt them.

Thanks.
