I don't have a D4 but I assume it is similar to the D3s. Do you remember whether the green focus dot was showing in the viewfinder? Where was the focus point selector switch set? Try it on single focus point, if you were all the way up to camera picks focus point it is possible that it wanted to focus on something closer. Are you sure you weren't accidentally in manual focus mode?
These are a few of the commonly encountered problems.
From the picture it appears that the camera was focusing even closer than the first bird. Is the first picture a crop?
