Tyler Blu Gunderson is one of the main protagonists of Rio, Rio 2, Angry Birds Rio, other video games, and all of the books of the franchise (with the exception of Rio No.3: A Dog's Tale, where he is only a minor character.). The other is Linda Gunderson.
In Rio, Tulio speculated that Blu was the last male of his kind, the Spix's Macaw. He is shy and socially awkward, and is definitely the opposite of his mate, Jewel. While he can log onto a computer, open bird cages and use a skateboard, he had one major setback: he is unable to fly. When he met Jewel and fell in love with her, he was forced to put his fears aside and find out if he really had what it took to soar.
