Bird arms

Dinosaurophiles:

All this talk about secondarily flightless dinosaurs has got me wondering...
How come, when flying dinosaurs decide to return to the ground, they usually
reduce the arms, in some cases making them mere vestiges or practically
nonexistent?  Wouldn't it make more sense to evolve "normal" arms again, since
you're not using them for flight anymore?  Boy, evolution is full of weird
quirks...
