I only ever did one Dallas trip, and I think it was only the third time they'd seen an A380. It was all very pleasant.
As mentioned by Daver6, it might have been an aircraft in front of you, in which case it was possibly ATC initiated. You can't see birds far enough ahead to be able to avoid them. Generally it's a case "birds" followed by an immediate "splat". I certainly wouldn't go around for a bird strike anywhere on finals.
I was once on approach to Jakarta, and there was some discussion about a NOTAM warning about birds. The FO made a comment that he'd never had a bird strike. Pretty much exactly as he finished his comment, I noticed a small black spot in the sky, which was rapidly getting bigger. It arrived on the FO's windscreen and provided the perfect full stop for his comment.
