Bill,
From BONO Ross's account:
Johnsgard (2012) estimated that some 2% of white geese migrating through Nebraska are Ross’s Geese; since the mid-continent flock of Snow Geese numbers some 4.9 million, Johnsgard (2012) estimated that some 90,000 Ross’s Geese pass through Nebraska. More recent estimates indicate the number of Snow Geese in the mid-continent may be 2-4 times greater than 4.9 million (Mark Vrtiska, NGPC, personal communication). Thus, the estimated number of Ross’s Geese migrating through Nebraska would be proportionally higher as well.
Hope this helps!
Ross

Thanks for adding Snow/Ross's, Joel!
Based on careful examination of individuals in flocks, any idea what the usual ratio of Snow to Ross's would be?
