Narrative:

At about 5800 ft; bird struck copilot's window. Did not see prior to strike; but from the remains; it appeared to be large. About 1 min later; numerous EICAS messages appeared relating to the left engine. I immediately noticed the oil pressure for the left engine was reading '0' and the egt was at '165;' compared to the right engine egt reading of '365.' no noticeable flight change since thrust levers were already at idle for the descent. Due to the just occurring bird strike; I suspected a possible bird intake in the left engine. Was concerned about the right engine and closely monitored it. I shut down left engine per QRH and declared an emergency with approach. Since WX was VMC; I asked for the visual to runway and backed it up with the ILS. First officer was flying at the time and continued to fly the aircraft with autoplt on as I ran checklist and continued with PNF duties. First officer landed uneventfully. Upon block-in; noticed 2-3 additional bird strike marks; 1 on captain's #2 window; and 1 or 2 marks on radome under captain's window.

Title: BIRD STRIKES ON APCH RESULT IN ENGINE SHUTDOWN FOR B757-200 FLT CREW.

Narrative: AT ABOUT 5800 FT; BIRD STRUCK COPLT'S WINDOW. DID NOT SEE PRIOR TO STRIKE; BUT FROM THE REMAINS; IT APPEARED TO BE LARGE. ABOUT 1 MIN LATER; NUMEROUS EICAS MESSAGES APPEARED RELATING TO THE L ENG. I IMMEDIATELY NOTICED THE OIL PRESSURE FOR THE L ENG WAS READING '0' AND THE EGT WAS AT '165;' COMPARED TO THE R ENG EGT READING OF '365.' NO NOTICEABLE FLT CHANGE SINCE THRUST LEVERS WERE ALREADY AT IDLE FOR THE DSCNT. DUE TO THE JUST OCCURRING BIRD STRIKE; I SUSPECTED A POSSIBLE BIRD INTAKE IN THE L ENG. WAS CONCERNED ABOUT THE R ENG AND CLOSELY MONITORED IT. I SHUT DOWN L ENG PER QRH AND DECLARED AN EMER WITH APCH. SINCE WX WAS VMC; I ASKED FOR THE VISUAL TO RWY AND BACKED IT UP WITH THE ILS. FO WAS FLYING AT THE TIME AND CONTINUED TO FLY THE ACFT WITH AUTOPLT ON AS I RAN CHKLIST AND CONTINUED WITH PNF DUTIES. FO LANDED UNEVENTFULLY. UPON BLOCK-IN; NOTICED 2-3 ADDITIONAL BIRD STRIKE MARKS; 1 ON CAPT'S #2 WINDOW; AND 1 OR 2 MARKS ON RADOME UNDER CAPT'S WINDOW.
