It had been a long day. Leg 1 on landing had a bird-strike at ZZZ1 Runway 33. After maintenance cleared the plane to continue flying; we continued with our day. We struggled all day long to catch up to the schedule. We were running about 1 hour late. It looked like we were closing in on making that time less as we were flying to ZZZ1 on the third leg. A brief discussion occurred between all crew members during the cruise from ZZZ2 to ZZZ1. We were all starving. So. Even though we were making that time up and closing in on only being 30 min delayed....food for the crew along with a big gate swap from new terminal to gate 23 two terminals over; ensured that we would remain 1 hour late. So. all was good and there we were airborne and on the way to ZZZ and trying to make up time and beat what was now almost a 12 hour duty day....and we had been informed by deadheading crew of this poor guy in the back who had a time limit to get to ZZZ to propose to his fiancée.There we are. All is well and we are direct ZZZZZ. We are rather far away in Pennsylvania with this direct ZZZZZ for the visual/ILS to Runway 4 @ ZZZ.Everything is appearing normal except approach control decides to slow us down/vector us to the west of the Runway 4 approach course. So there we are flying low and slow 3000 feet and 170 knots.We finally get vectored back to intercept the approach course to Runway 4. Upon declaration of a visual on the airport; we are cleared for a visual approach and switch to the tower. We were prior to the final approach fix; ZZZZZ1; and we are gear down and cleared to land on Runway 4.All I know; is that distractions and get home itis are rather real events and are considered distractions. I am so aware of distractions and how disastrous distractions can be. Especially in non ideal conditions. Up until this point and for all these years I have worked so hard to not allow any distractions. Unfortunately; on this date I succumbed to all of our day distractions and information/data…such as bird-strike; aircraft damage; delays; airplane swaps; terminal swaps; 11/12 hour duty day.I am hand flying the visual approach to Runway 4 at ZZZ; when...too low flaps. Is annunciated. The First Officer looks immediately and says O; flaps and immediately declares a go around. The go around is accomplished straight ahead to 3000 feet and then vectored to a left down wind for Runway 4. West reloads the approach on the downwind. I make an announcement to the passengers in order to not alarm them off the balked approach to landing.On the second visual approach to Runway 4. we are hyper aware to dump distractions and the second approach to land at Runway 4 ZZZ is a non event.
Approaching ZZZ on the 4th leg of an 11.5 hour duty day; we began approaching ZZZ over an hour behind schedule due to maintenance and ramp delays on previous legs. We began configuring early due to being sequenced behind a helicopter to the airport. Gear down and flaps 3 were well ahead of schedule. Began descending down the glide slope. Too low flaps was annunciated. Performed go around and landed without further incident.Suggestions; stricter adherence to appropriate checklist timing. More awareness regarding acute fatigue not involving lack of sleep. More training with regards to atypical scenarios on approach due to outside factors. Primary factor I believe was acute fatigue stemming from the early showtime and the earlier delays beginning with a bird strike on leg 1; as well as fatiguing turbulence on all 4 legs.
EMB 175 flight crew reported a 'too low flaps' alert occurred during approach resulting in a go-around. The flight crew stated multiple distractions and fatigue contributed to not configuring the aircraft properly for approach.
