Narrative:

At rotation on takeoff we had a surge on left engine with a loud bang. The EPR (engine pressure ratio) dropped to approx. 1.60 then returned to normal with a brief mc (master caution) light. All 3 fas called and said 'we have a real bad odor with smoke' we then [advised ATC] and returned to [the departure airport]. Also a deadheading pilot told a flight attendant that we might have a blown tire. We really didn't know what we had. The tower had had the runway checked for debris. It was clean. After landing the aircraft was checked out then we taxied to gate. It was an overweight landing 140;000 lbs. The post flight walk around showed signs of bird remains in left engine. Fas did a great job and the passengers seemed to be in good spirits.

Narrative: At rotation on takeoff we had a surge on left engine with a loud bang. The EPR (Engine Pressure Ratio) dropped to approx. 1.60 then returned to normal with a brief MC (Master Caution) light. All 3 FAs called and said 'we have a real bad odor with smoke' We then [advised ATC] and returned to [the departure airport]. Also a deadheading pilot told a FA that we might have a blown tire. We really didn't know what we had. The tower had had the runway checked for debris. It was clean. After landing the aircraft was checked out then we taxied to gate.
