Observation details
Estimate from the attached photo viewed on a computer screen with photo managing software which allowed zooming in to see detail. Method used was to select a typical 0.5" strip and, using the grouping method, estimated the number of geese in the strip to be 125. The mass of geese measured over 8" in length on the screen. Then multiplying 125 by 16 got 2000. Assuming the depth of the geese in the mass was 5, this yields 10,000. Note that this mass of snow Geese was seen across the lake about 2 miles from our location on the viewing platform. Identification was made from the photo after we got home and had access to our computer.
