Narrative:

During takeoff roll; at approximately 100 KTS; captain called out 'bird.' I saw an extremely large hawk with a 4+ ft wing span sitting on the runway. As we approached; it attempted to fly away. After several maneuvers; the bird passed by the cockpit on left side with a subsequent very loud bang and engine surge. I called 'abort' and the captain executed the abort at 121 KTS. Rejected takeoff engaged with no issues noted. After call to tower about aborting; tower queried if assistance was required and after a brief discussion with the crew we decided against it due to the lower airspeed abort which was initiated. Relief pilot ran brake cooling chart and we were close to the melt zone. Upon clearing the runway and taxiing to the gate; the brake temperature annunciator light illuminated. The captain decided to request fire fighting equipment as a precaution and we were directed to taxi to a deice pad. Fire crew told apron who told us a 'small fire; under control on the right tires/side.' evacuate/evacuation was discussed and we decided against it at that time. After normal precautions; passenger and crew were off-loaded with no incidents.
