The captain and co-pilot reported that, about 1 nm from the final approach fix and about 4,000 ft above the ground, the airplane shuddered. During this time the co-pilot heard multiple loud thuds and realized they had collided with a flock of birds. The flight crew did not detect any unusual flight characteristics for the remainder of the flight and landed without further incident. The airplane sustained substantial damage to the inboard leading edge of the left wing. The flight crew reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
