Narrative:
Taking off from runway 31C at mdw in a B737-200, we ingested a bird (or 2) in the #2 (right) engine. It started to compressor stall and we brought it back to idle. There was no overheat and/or fire condition and engine parameters were normal. We elected to keep the engine in idle power. We declared an emergency, completed all checklists and landed the aircraft using single engine landing procedures on runway 31C. We believe the bird type was a seagull and they had been sitting on the runway down at the far end. We did not see any bird activity until we started to rotate (past V1). I have previously seen seagulls around mdw and they probably are there due to lake michigan.

Title: B737-200 HAS BIRD STRIKE WHICH IS INGESTED INTO THE ENG ON TKOF AND ACFT TENDS TOWARD A COMPRESSOR STALL. FLC BRINGS PWR TO IDLE, DECLARES EMER. BIRD STRIKE. EMER DECLARED.
Narrative: TAKING OFF FROM RWY 31C AT MDW IN A B737-200, WE INGESTED A BIRD (OR 2) IN THE #2 (R) ENG. IT STARTED TO COMPRESSOR STALL AND WE BROUGHT IT BACK TO IDLE. THERE WAS NO OVERHEAT AND/OR FIRE CONDITION AND ENG PARAMETERS WERE NORMAL. WE ELECTED TO KEEP THE ENG IN IDLE PWR. WE DECLARED AN EMER, COMPLETED ALL CHKLISTS AND LANDED THE ACFT USING SINGLE ENG LNDG PROCS ON RWY 31C. WE BELIEVE THE BIRD TYPE WAS A SEAGULL AND THEY HAD BEEN SITTING ON THE RWY DOWN AT THE FAR END. WE DID NOT SEE ANY BIRD ACTIVITY UNTIL WE STARTED TO ROTATE (PAST V1). I HAVE PREVIOUSLY SEEN SEAGULLS AROUND MDW AND THEY PROBABLY ARE THERE DUE TO LAKE MICHIGAN.
