This was my fourth approach down to low minimums on this date; which was having micro burst alerts and windshear alerts on the departure end. Then reported windshear on takeoff and a special Cat II approach to mins back at [the departure airport]. The third leg to SMF required a CAT III approach; but as we were in the approach the weather started to lift. About 1000 ft. we encountered a flock of between 60-80 geese on a collision course; just as we were trying find an escape route the flock separated and went on both sides of the aircraft. We continued the approach when at approximately 600 agl I received NO AIII in the hud; at which point we executed a missed approach. As we setup to come back for another approach the weather had risen to CAT I and was getting better. We setup for a CAT I ILS approaching 1000 agl we had more geese to maneuver around; we were stabilized at 1000agl and still vmc. Not long after the 1000 foot call I saw more geese staying centered on my windshield. I started to maneuver left and high to avoid the geese; after passing the geese I was high and left of course; I started correcting back to course and my FO said I was 2 dots high so I said correcting. I lower the nose too much and got a SINK RATE -I corrected the sink rate and had the runway in sight. We touched down within the first 1500 ft. I was so focused on the runway and getting back to stabilized approach that my First Officer's call out to go around did not register until just prior to touchdown. First I feel the stress of avoiding multiple geese strikes caused me to get tunnel vision to establish a stabilized approach and land the airplane safely. My First Officer correctly said 'go around' however in my intense concentration it didn't register. The outcome was a safe landing and no geese strikes; but my correct course of action should have been a go-around.

Boeing 737 flight crew encountered a flock of geese at 1;000ft. The Captain maneuvered to avoid the birds and ended up high and left of the ILS. During his correction; the crew got a sink rate call out and continued to land in an un-stabilized approach condition.
