Rio is a man's name? Well Duran Duran's famous song "Rio" was about a woman called Rio ("Her name is Rio and she dances in the sand...."). So can it be a girls name.
A movie called Rio is coming out about parrots or some tropical birds trying to get to Rio de Janeiro. I'm not sure but I think the main character bird is named Rio too. So now I picture a blue parrot with the name Rio.
I like this name for a boy. It would only look good on a Hispanic boy though. It's pretty cute and I can see a middle aged or elder man with it too:)

I am Brazilian, and even though I've enjoyed visiting Rio de Janeiro, I don't think I'd name my kid after it. It would look ridiculous. Besides, to a lot of people, "Rio" reminds them of Hollywood's weird image of Brazil - you know, soccer, favelas, and women wearing fruit hats.
