Narrative:

Climbing out at approximately 4;000 feet we experienced multiple bird strikes. We [notified ATC] and started a return to [departure airport]. The number 2 engine had extremely high vibration and was compressor stalling. The engine stall checklist was accomplished. The remainder of the flight was accomplished with the #2 engine at idle in order to prevent further compressor stalls. Dispatch was contacted and landing data requested for a north landing. The captain advised the flight attendants and passengers of the situation. We requested and flew a visual approach to runway 34R where we rolled to the end; exited and secured the right engine. We requested airport fire and rescue examine the aircraft before proceeding to the gate to deplane normally.
