The First Officer on an air carrier medium twin jet reported contact with multiple birds after takeoff from DEN. They returned to DEN for a precautionary overweight landing.

Narrative

We departed Runway 8 on a 095 heading. I had just completed the climb checklist; looked outside; and called out 'birds' as I noticed a large flock of medium to large size birds approaching from our right. A split second later; we penetrated the flock and noted what sounded like multiple loud bird strikes. This occurred at 7;500 FT (2;000 FT) AGL. We reported the bird strike to the Tower; leveled off at 8;000 FT; and decided it would be best to return to the field. We entered a right downwind for 35R. [The Captain] talked to the passengers and flight attendants; and we notified Operations of our return. All checklists were completed; and we executed an overweight precautionary landing at DEN with no further irregularities occurring in flight. The post flight revealed multiple areas of bird matter around the right leading edge flap assembly; under the inboard right wing; and side of the right engine cowling. Maintenance cleaned and inspected those areas; performed the overweight landing inspection; and no defects were noted. The flight departed shortly thereafter without further incident.
