Narrative:

First officer was flying the leg from ZZZ to ZZZ1. After the flaps were retracted and we were given a heading off the SID; at about 5000 ft; he brought to my attention that the oil pressure on the #1 engine was zero and was highlighted in red. I declared an emergency with departure control and told them we would be returning to ZZZ for an immediate landing. As per the preflight briefing; the first officer flew the aircraft and handled the ATC radios. I referred to the QRH; shut down the left engine as directed; briefed the flight attendants; made a PA to the passenger; contacted dispatch; then followed through with the mechanical checklist. I spoke with the arff chief on the discrete radio frequency and told him that we planned on stopping the aircraft and having them look us over; after landing. We also struck 2 birds in the flare. This was reported to the tower; who had airfield management search the runway. They followed us to the gate and told me that they had found 2 doves on the runway. We landed at 202000 pounds; which was 4000 pounds over maximum landing weight. The touchdown rate was 100 FPM and very smooth. After landing we stopped the aircraft and the arff crew inspected the aircraft and found no visible abnormalities. We received clearance to taxi to gate and were followed by the arff crew and airfield management. After arriving at the gate; a maintenance supervisor met the aircraft. The oil quantity read 18 quarts in the left engine; which may indicate a failure of a pump or transmitter; rather than a busted line. I called dispatch on the radio and answered all of his questions; then filled out the logbook; with 3 entries; loss of oil pressure in the left engine; overweight landing; and bird strike.

Title: A B757-200 FLT CREW EXPERIENCED LOSS OF OIL PRESSURE ON TKOF. THEY DECLARED AN EMER AND RETURNED TO LAND OVERWT AT DEP ARPT; STRIKING 2 BIRDS IN THE LNDG FLARE.

Narrative: FO WAS FLYING THE LEG FROM ZZZ TO ZZZ1. AFTER THE FLAPS WERE RETRACTED AND WE WERE GIVEN A HDG OFF THE SID; AT ABOUT 5000 FT; HE BROUGHT TO MY ATTN THAT THE OIL PRESSURE ON THE #1 ENG WAS ZERO AND WAS HIGHLIGHTED IN RED. I DECLARED AN EMER WITH DEP CTL AND TOLD THEM WE WOULD BE RETURNING TO ZZZ FOR AN IMMEDIATE LNDG. AS PER THE PREFLT BRIEFING; THE FO FLEW THE ACFT AND HANDLED THE ATC RADIOS. I REFERRED TO THE QRH; SHUT DOWN THE L ENG AS DIRECTED; BRIEFED THE FLT ATTENDANTS; MADE A PA TO THE PAX; CONTACTED DISPATCH; THEN FOLLOWED THROUGH WITH THE MECHANICAL CHKLIST. I SPOKE WITH THE ARFF CHIEF ON THE DISCRETE RADIO FREQ AND TOLD HIM THAT WE PLANNED ON STOPPING THE ACFT AND HAVING THEM LOOK US OVER; AFTER LNDG. WE ALSO STRUCK 2 BIRDS IN THE FLARE.

I CALLED DISPATCH ON THE RADIO AND ANSWERED ALL OF HIS QUESTIONS; THEN FILLED OUT THE LOGBOOK; WITH 3 ENTRIES; LOSS OF OIL PRESSURE IN THE L ENG; OVERWT LNDG; AND BIRD STRIKE.
