SX-50 - Low light / Action shots - disappointing

The Bird below was shot ISO 400, 1200 mm, 1/125 Second, Aperture 6.5.

The Photo was taken around 6 PM (in fading light). It came out Pitch Black - Thanks to the wonder of Lightroom, the image has been recovered nicely.

Do the rest of the SX-50 owners experience this terrible graininess at ISO 400?

Am I doing something wrong with my settings to wind up with barely usable images?

Feedback / advice appreciated. Thanks.
