The Baby Macaws are Blu and Jewel's offspring. While they are heard singing at the end of the film during "Real in Rio" for half a line, their voice actors aren't listed in the end credits. They will also appear in the opening scene of Rio 2.
It has been revealed by one of Rio 2's producers that two of the chicks are male and that one is female and that two of the completed story boards, including the opening scene, will involve them. Blu and Jewel will also have a second Brood of offspring which will be two girls named, Bia and Carla and a son named Tiago
