Narrative:

Had just crossed over midfield getting ready to enter left downwind for at ZZZ (uncontrolled field). Aircraft was level at 1500ft; flaps 20deg; 160kts IAS. Just as I was getting ready to turn downwind I saw a flash go by the left window (what appeared to be a goose from surrounding birds). The bird flew into the left engine causing the N1 to start rolling back. There were no warning lights (oil pressure; hydraulic; etc) as at that time the core of the engine was still running. However due to a bad vibration caused from the strike we had to shut the engine down. We continued in the pattern and landed safely with no issues. Did not declare an emergency (was on unicom with no other traffic) and didn't roll the trucks as there was no fire (just single engine landing).
