Bluebird is really Sally Avril, a classmate of Peter Parker's who had no idea that the quiet nerd was really her friendly neighborhood Spider-Man.  Wishing to become a famous superhero, Sally added some dodgy tech to her gymnastic skills, donned a costume and called herself the Bluebird.  She died in a car accident in the Mainstream Marvel Earth-682.

But on Earth-682, the native version of Bluebird survived and might even thrive given that there is a school dedicated to super heroic teens and loons in silly outfits.  Now she is a provisional member of the Wonders, the Junior Team secretly being trained at the Stanley School.
