Narrative:

While on approach to bwi approximately 8 miles to the east and on vectors for runway 33L; approximately 8;000 ft MSL; and 250 KTS assigned; we heard a loud bang from the nose area. I immediately recognized the sound as a probable bird strike. We scanned the engine instruments right after; and noticed the left N2 vibration monitor jumped to around 4.0 then settled down to around 3.0. We notified ATC; who then gave us a more immediate vector towards the final for 33L; and cleared us for the visual approach; and to land. Upon inspection at the gate; the mechanics and we found evidence of a relatively large bird strike on aircraft right nose area slightly aft of the radome; with no structural damage noted at the time. Further inspection revealed blood on the leading edge of the right wing; and what appeared to be blood evidence on the leading edge of the right engine intake cowl. We also noted; with the mechanics as the left engine N1 fan was spooling down; what appeared to be a dark area on a couple of the fan blades. An entry was made in the logbook; and aircraft was taken out of service; pending a borescope inspection. We were given another aircraft; and completed our next flight; without incident.

Title: Captain experiences a bird strike at 8;000 FT 8 NM east of BWI on vectors for approach causing an elevated N1 vibration reading for the right engine. After landing evidence of a relative large bird strike is found on the right side of the nose; right wing root; and right engine cowl and fan blades. Aircraft is taken out of service.
