Noting the north winds and peak time of year, we headed to Boiler Bay hoping for a good shorebird day and were not disappointed. Spectacular, with waves of peeps flying northward in large flocks. Numbers were so impressive that I resorted to counting how many flocks flew past. I tallied just over eleven hundred large flocks (200-300+ birds, some flocks up to 2000+) and many smaller groups. Clearly hundreds of thousands had migrated past. The movement gradually moved further offshore, but I was still tallying endless flocks of two to three hundred peeps until we left. At times many thousand would pass close by in only a few minutes. Our final estimate was 330,000 but we rounded down slightly. I think this number is conservative, as it was easy to underestimate flock sizes, and we were often missing flocks when our focus turned to something else.
