Observation details

I photographed this flock in sections using background objects as reference points. I then brought the pictures up on the computer screen, counted the number of birds across the picture, counted the number of birds deep in the picture, and multiplied those two numbers. I then added all of the pictures together. and subtracted a few thousands to be conservative. I then chose an arbitray numer of 95% Ross vs 5% Snow Goose to arrive at the above numbers.
