This is how I think it happened, based on my studies: http://img.photobucket.com/albums/v165/captmicha/New/1.jpg
I think that the "birds" that people think developed from dinosaurs were just amongst the first developments taking place to take advantage of the benefits of flight. It could have developed from small dinosaurs climbing from tree to tree and leaping. We have bats after all, gliding squirrels and lizards too.
I think that the birds we know today are offshoots of reptiles that developed flight and the characteristics needed for flight like enlarged hearts, warm "bloodedness" and such.
