FO was PF. During takeoff roll at MTPP right at rotate speed; a bird in the cockpit suddenly flew from the Capt.'s left side to cross in front of the Capt.; across the window; bumping off the window/glare shield in front of me; and then headed right toward my face; causing me to lean out of the way as it brushed by my face while I was pulling the aircraft nose up through rotation. Aircraft control was not compromised. The bird passed by me; and we were unable to locate it for the duration of the flight. Presumably it escaped our view in a small crevasse and perished.Prior to departing ZZZ for the MTPP turn; the aircraft was on the ground for three days. It was towed from the maintenance hangar to our gate. As I boarded the aircraft for preflight duties at ZZZ; ground personnel was attempting to remove a pigeon from the cabin and apparently succeeded. The electronic maintenance log indicates that a pigeon was removed from the aircraft; but unclear to me whether that entry refers to the preflight pigeon or our inflight bird of unknown species. We were aware of no other in-the-aircraft bird activity.On the ground in MTPP; ground personnel secured the jet bridge door in the open position throughout the ground time. There is a remote possibility the bird joined us from there too. Regardless of where our avian friend originated that day; it most likely entered the aircraft through open doors; especially if the aircraft was left open for days prior to the flight. As such; I recommend the review of the existing guidance for leaving aircraft doors open for extended periods of time and determine if the guidance is inadequate; or simply not followed in this event.
Air carrier First Officer reported being distracted during takeoff roll by a bird which emerged from inside the cockpit. Aircraft control was maintained at all times and the bird subsequently disappeared for the remainder of the flight.
