Narrative:

Shortly after liftoff at approximately 600 feet AGL; I saw a bird moving from right to left across the path of the aircraft. Immediately after seeing the bird; the bird struck the aircraft on the left side. As PIC; I elected to continue the flight. After being cleared to and leveling at 10;000 MSL the master warning indicator began flashing and the left oil pressure low light activated. I immediately pulled power on engine 1 (left) to idle and observed the left oil pressure indicator to be well below normal. I contacted approach to alert them to our situation and requested an immediate return to [departure airport].once the airplane was established in an appropriate heading and descent for a return to the airport; I elected to shut down engine 1 (left) to prevent any further damage. I brought engine 1 power lever back over the gate and it was successfully shut down. I then conducted an approach and landing. After landing; I was able to taxi the aircraft to parking.
