INCREDIBLE! Long narrow raft extending from center to rear of lake. I took several photos along the raft. I then selected three representative photos of dense, medium, and sparse distribution. I added them together and divided by 3. I moved my camera from one end of the raft to the other and came up with 43 frames. I added 6 frames from an adjacent raft. I multiplied the average by 49. Possibly low as there were more birds at the rear of the lake that I could not identify. Later some ducks moved up closer for a better detail shot. The swans seen in the second photo are the same as the ones in the far left of the next photo to give an idea of the size of the rafts.
