Narrative:

We were climbing out at about 9000 feet when I saw approximately a half dozen medium sized birds heading toward the windscreen and down the right side of the airplane. One hit right above my head and the others hit some parts of the aircraft on the right. The audible booms were very noticeable as was the obvious pitch sound change coming from the right engine. We immediately received a call from the fas asking what the loud booms were about. All engine indications appeared normal and within limits. Flight controls were also functioning properly. However; given what we saw; heard; and felt we made an immediate decision to return to [departure airport]. We were given priority handling and landed uneventfully. Upon exterior inspection of the airplane we saw blood stains right over the cockpit window and on the forward; inner wing root; right side. We also saw significant damage done to the right engine cowl and several fan blades.
