Right engine of a B757-200 ingested an eagle on climbout. Returned under emergency declaration.

Narrative

Takeoff heading 345 degrees; we hit what appeared to be an eagle at 7;500 FT with our right engine. A loud bang was heard; followed by 2 or more compressor stalls. I told First Officer we were going back to declare an emergency; which he did. Departure Control gave us a left upwind turn for a visual to Runway X. After the compressor stall; the autothrottle must have disengaged and I subsequently and inadvertently oversped flap 1 degree to a speed of 250 KTS. We then started configuring for flaps 5 degrees; 180 KTS. First Officer told Flight Attendant we were returning to field; no preparation. I decided the safest thing to do was to bring the aircraft right around and land while I still had '2 engines' and before the right came apart. We turned final just outside FAF for Runway X. Ran final descent checklist. We were stabilized flaps 30 degrees; reference +8 by FAF. We touched down normally and taxied to gate with emergency equipment in tow. No injuries except to eagle and engine. On base; I made a quick announcement to passengers and Flight Attendants that we hit a bird and were going to return for a safe landing. Supplemental information from ACN 822153: The autothrottles had shut off and we didn't realize it. On final approach; the right engine was still running but was very rough; and we discussed the possibility of it quitting. Upon inspection; there was severe damage to the right engine cowl; fan blades; and inner engine area.
