觀察細節
A large raft comprised of mostly GRSC with a few LESC mixed in. The raft was distant making it difficult to accurately assess the ratio of Greater to Lesser. I took a couple of "panoramic" photos of the raft starting on the right side and then moving left which I have attached. There were more birds strung out further to the left, perhaps another 100 individuals or so not captured in these two photos. I then attempted to count by tens the number of individuals in these two photos and came up with 1030. Add in the roughly 100 individuals not in these two photos and the birds that were underwater makes me reasonably confident in the accuracy of the reported tally.
