**exact count** Counted individually, almost all traveling in pairs from south to north in the S. Marin CBC count circle. Double counting seems unlikely considering we saw very few MAMU flying towards SF. Almost all but 2 pairs were seen when moving south/east off the stretch from Rodeo Beach to Kirby Cove. 22 were seen flying from SF waters. Edit: The original MAMU count for this checklist was 81. That is the total MAMU count for the survey but not for Marin Co. waters. As we boated we saw only 6 individuals sitting on the water. All others were either originally observed in Marin Co. waters or seen flying into them.
