Unless the birds are sitting still... AI Servo. You might also want to swtch to continuous shooting mode (rather than single-shot) to increase your odds of getting a great shot of moving subjects.

Never use servo AF for still targets. Otherwise when you recompose, the subject would be blurred and you'd get many ruined shots.
Switch to servo ONLY when you know for sure that you are going to seek flying birds.
