Narrative:

We briefed a flaps 2; toga; bleeds off take off from runway 27. After takeoff; we noticed that we had forgotten to select the engine bleeds off. I believe two items contributed to our omitting to select the engine bleeds off as we had briefed. 1. As bos was using runway 27 for takeoff; I elected to do a single engine taxi to conserve fuel. Taxiing from our gate to runway 27 involved crossing 3 runways and a taxi route that I was not very familiar with. While we remained focused on the taxi route and coordinating clearance to cross the 3 runways enroute to runway 27; we also became distracted from our bleeds off SOP set up. As an additional distraction; the first officer was also tasked with starting the number 2 engine while backing me up with the taxi route. 2. I also believe that fatigue was a contributing factor in our SOP omission. This was day three of a trip with a wake pattern of early; early; and earliest. Day one involved a xd:00 domicile time wake up. Day two was xd:15 and day three was a xa:45 domicile time wake up. While I felt fit to fly; I also felt tired from the very early wake up on day three. I will try to be more careful and deliberate with SOP compliance and give more consideration to minimizing distractions; especially when fatigued in the future.
