The pilot reported that while on short final, two flocks of geese departed the field in front of his airplane; "no immediate evasion action was necessary". During the landing roll, the airplane began to swerve and veered off the runway to the left. The pilot reported that he "over-applied brake" and subsequently nosed over after attempting to avoid the runway edge lights.
The pilot reported there were no pre-impact mechanical failures or malfunctions with the airframe or engine that would have precluded normal operation. The airplane sustained substantial damage to the empennage.
