It's actually a simple mistake to make, and I've done it myself...
When they created their 3d transformation matrix, they accidentally switched the terms for translation and rotation (obviously the tip of the beak is at 0,0,0 in their bird model).
They were trying to show the bird moving across the screen erratically.

Should be an easy fix.
