Narrative:

On takeoff roll, just after the '80 KTS' callout by the copilot, he also called out 'birds.' a loud single 'bang' was heard, and since we were still well below V1 speed, and not knowing if the 'bang' was a bird hitting the cockpit or a compressor stall, I elected to abort the takeoff. The abort was normal, straight down the centerline of the runway, with both engines operating normally in reverse thrust. I cleared the runway slowly at taxiway C, a 90 degree exit approximately 4900 ft from the takeoff end of runway 22. After notifying the flight attendants, passenger, and the tower of our safe status, we taxied back to our gate so I could make an inspection of the aircraft. While taxiing to the gate, I ran each engine up with both checking out normal. During my 'walk around' and close inspection of the engine and airframe, I could not find any trace or sign of a bird strike or ingestion in either engine. Since I saw no need for maintenance and after checking the brake energy chart for brake cooling time, I elected to continue the flight. All phases of the flight to atlanta were normal. Birds have been a problem for aviation forever, and other than 'loud sound devices' dispersed along the runways I don't have much to suggest.

Title: ABORTED TKOF. PROBABLE COMPRESSOR STALL POSSIBLE BIRD STRIKE.

Narrative: ON TKOF ROLL, JUST AFTER THE '80 KTS' CALLOUT BY THE COPLT, HE ALSO CALLED OUT 'BIRDS.' A LOUD SINGLE 'BANG' WAS HEARD, AND SINCE WE WERE STILL WELL BELOW V1 SPD, AND NOT KNOWING IF THE 'BANG' WAS A BIRD HITTING THE COCKPIT OR A COMPRESSOR STALL, I ELECTED TO ABORT THE TKOF. THE ABORT WAS NORMAL, STRAIGHT DOWN THE CTRLINE OF THE RWY, WITH BOTH ENGS OPERATING NORMALLY IN REVERSE THRUST. I CLRED THE RWY SLOWLY AT TXWY C, A 90 DEG EXIT APPROX 4900 FT FROM THE TKOF END OF RWY 22. AFTER NOTIFYING THE FLT ATTENDANTS, PAX, AND THE TWR OF OUR SAFE STATUS, WE TAXIED BACK TO OUR GATE SO I COULD MAKE AN INSPECTION OF THE ACFT. WHILE TAXIING TO THE GATE, I RAN EACH ENG UP WITH BOTH CHKING OUT NORMAL. DURING MY 'WALK AROUND' AND CLOSE INSPECTION OF THE ENG AND AIRFRAME, I COULD NOT FIND ANY TRACE OR SIGN OF A BIRD STRIKE OR INGESTION IN EITHER ENG. SINCE I SAW NO NEED FOR MAINT AND AFTER CHKING THE BRAKE ENERGY CHART FOR BRAKE COOLING TIME, I ELECTED TO CONTINUE THE FLT. ALL PHASES OF THE FLT TO ATLANTA WERE NORMAL. BIRDS HAVE BEEN A PROB FOR AVIATION FOREVER, AND OTHER THAN 'LOUD SOUND DEVICES' DISPERSED ALONG THE RWYS I DON'T HAVE MUCH TO SUGGEST.
