Narrative:

I was the first officer and flying pilot. As the first flight of the new day ca (captain) and I conducted a full briefing including reject and engine out procedures. Normal pushback and taxi out subsequently occurred on time. As we were cleared for takeoff and taxied into position. I performed my usual scan of the runway and did not see any runway hazards or reasons not to continue with the takeoff. Takeoff power was set and confirmed as we began our takeoff roll. As I was the flying pilot my eyes were outside the aircraft scanning the runway and maintaining runway centerline. Shortly thereafter I noticed a large flock of birds from one side of the runway to the other and I made a 'birds ahead' call to ca. Within a second of seeing the birds; one hit the windscreen and dozens passed both sides of the cockpit at engine level. Ca called for the reject; positive control transfer occurred; and ca performed the reject takeoff procedure. I informed the tower we were rejecting and made the PA announcement to 'remain seated; remain seated' to the passengers as we slowed. We cleared the runway; performed the reject-takeoff procedure in the QRH (quick reference handbook) and we determined that assistance as well as an evacuation was not required. No emergency was declared. Ca determined our speed at reject to be 110kts and we consulted the brake cooling chart in the QRH. We then returned to the gate and made the maintenance elb (electronic log book) report. There were no bird reports by preceding aircraft or any tower-issued reports.
