1500, 2500, 4000, 2000, 2500. Conservative estimate. They're spread out in the entire lake area and busy in foraging; so not much movement of the birds which made it easier to count. Can say individually counted till 10K+ and then added 2.5K for another patch at the end of the lake where the counts were massive too. Didn't count the birds hidden behind vegetation or on the opp. side of the bund, as visibility was limited. Could be easily 15K or more - G.
