Narrative:

Hit a flock of birds on departure from ZZZ just as we were making our final flap retraction. Both the first officer and I heard/felt a very loud bump on the right windscreen. We both saw a blur go by just prior to impact. We immediately smelled cooked feathers for a very short time. The flight attendants reported smelling it in the cabin as well. There were no abnormal engine indications. However; as we continued to fly the departure; we noticed the flaps were not fully retracted (flap handle between 1 and 0). We raised the flaps and continued to climb. At the time our airspeed was about 240-250 KIAS. I think the poorly timed bird strike was enough to interrupt our flow. Once we reached cruise altitude; we sent an ACARS message to dispatch to request maintenance when we reached destination. We were involved in an aircraft swap and the oncoming crew reported significant damage to the #1 engine. I was surprised because the only indication we had was the loud bump on the right windscreen and brief odor. I inspected the damage which included significant dents on the #1 engine cowling; one damaged fan blade; broken retractable landing light (#1) and lots of blood on the wing. If I had known the extent of the damage at the time of the bird strike I definitely would have returned to ZZZ.

Title: BIRD STRIKES AT 1500 FT DURING TKOF CAUSED B737-300 ENG; WING; AND LNDG LIGHT DAMAGE.

Narrative: HIT A FLOCK OF BIRDS ON DEP FROM ZZZ JUST AS WE WERE MAKING OUR FINAL FLAP RETRACTION. BOTH THE FO AND I HEARD/FELT A VERY LOUD BUMP ON THE R WINDSCREEN. WE BOTH SAW A BLUR GO BY JUST PRIOR TO IMPACT. WE IMMEDIATELY SMELLED COOKED FEATHERS FOR A VERY SHORT TIME. THE FLT ATTENDANTS RPTED SMELLING IT IN THE CABIN AS WELL. THERE WERE NO ABNORMAL ENG INDICATIONS. HOWEVER; AS WE CONTINUED TO FLY THE DEP; WE NOTICED THE FLAPS WERE NOT FULLY RETRACTED (FLAP HANDLE BTWN 1 AND 0). WE RAISED THE FLAPS AND CONTINUED TO CLB. AT THE TIME OUR AIRSPD WAS ABOUT 240-250 KIAS. I THINK THE POORLY TIMED BIRD STRIKE WAS ENOUGH TO INTERRUPT OUR FLOW. ONCE WE REACHED CRUISE ALT; WE SENT AN ACARS MESSAGE TO DISPATCH TO REQUEST MAINT WHEN WE REACHED DEST. WE WERE INVOLVED IN AN ACFT SWAP AND THE ONCOMING CREW RPTED SIGNIFICANT DAMAGE TO THE #1 ENG. I WAS SURPRISED BECAUSE THE ONLY INDICATION WE HAD WAS THE LOUD BUMP ON THE R WINDSCREEN AND BRIEF ODOR. I INSPECTED THE DAMAGE WHICH INCLUDED SIGNIFICANT DENTS ON THE #1 ENG COWLING; ONE DAMAGED FAN BLADE; BROKEN RETRACTABLE LNDG LIGHT (#1) AND LOTS OF BLOOD ON THE WING. IF I HAD KNOWN THE EXTENT OF THE DAMAGE AT THE TIME OF THE BIRD STRIKE I DEFINITELY WOULD HAVE RETURNED TO ZZZ.
