Narrative:

Bird strike at takeoff caused left engine stall/surge; loss of thrust. Turkey vulture type of large bird entered left engine at low altitude; causing loud repeated banging noises and vibration along with fireballs exiting tailpipe. Engine N1 and egt fluctuated and smoothed out after autothrottles disconnected and thrust lever retarded about 20%. We left the engine running at about 50% N1; started APU and completed engine stall/surge checklist. Advised ATC that we were returning to ZZZ. We were airborne for 17 minutes. Reviewed single engine landing checklist. Landed uneventfully with excellent support from airport emergency services. Large birds in the area. Company training made this an easily handled event.
