Деталі спостереження
Estimated by 500s in flocks in relatively close groups, = ca 18,000, the far flock on water appeared even larger, so used a conservative 20,000 for that group. Finally to the NE there were several thousand in the air swirling above the water- estimated 5,000 for that. I consider this a conservative estimate of that group. Just under a thousand were leaving when I arrived. About 800 perched on roof top of boat storage area. Suspect if a more accurate estimate were made it might be over 50,000 were present.
