D800 inconsistent focus may be fixed

The other day I was shooting (with the D800, not the gun) a beautiful red fox on a snowy field. Imagine the contrast: a red fox against a white background. Does it get better?

I took 11 shots of the fox. The camera was set at AF-C single point and NONE of the shots turned out usable because the camera couldn´t focus properly!

This isn´t the only encounter I´ve had with this behaviour of the D800. It seems unable to focus on anything from horses to furry wildlife. The number of unusable shots of deer I have is ridiculous, and for every sharp shots of my Welsh springers I have ten OOF.

It´s been said before: the D800 is a superb sensor in a mediocre (at best) shell.
