7D may be marginally better but not much - I own both.
In instances like this my 1D Mark III is what I would use. Even at ISO 800, noise is low. But of course more $$$ for the pro cameras. 5D Mark II is excellent at high ISO with low noise but AF is too sluggish for ducks and with a full frame sensor making a 500mm needed.
50D and some good noise reduction software may be the way to go.
