From the series, "Cuentos Foneticos", early reading books designed to teach Spanish phonics. In "El Pajaro Rojo", a gardiner finds a little red bird and puts it in a cage, but the bird is so sad, it won't eat or sing, no matter what advice the other animals give the gardiner. Finally he sets it free, and the bird can be heard singing again. The phonics practiced in this book are syllables with "ja", "je", "ji", "jo", and "ju".
