观察细节
Huge feeding aggregation. Nearly impossible to count because of the constant movement of trailing birds to the front edge of the flock. I reached 10,000+ on two occasions (in blocks of 50) counting from the front to the back (opposite the direction of flock movement). Videos to be uploaded. Estimated count somewhere between 15,000 and 20,000.
