Well, with a name like Flamebird...what else are ya gonna have her powers be?
Funny you should say that, DC's Russian heroine who took the name Firebird as a member of "Soyuz" (Sort of Soviet Teen Titans) was a telepath, who deliberately chose a name which had bugger all to do with her powers so people wouldn't suspect what her powers were... of course, the fact that her team-mates were named after a water nypmh (Rusalka), wind-djinn (Vikhor), ice demon (Morozko) and thunder god (Perun) who all had powers to match their codenames, showed that it clearly wasn't an idea she wanted to take too far.
