"A fall flight similar to or larger than that of 2005 is expected" P 42
And the winter count was off by another 5%, and has averaged a 3% per year in reduction in recent years. This tell us that possibly the spring CO is working. See fig 21, of the winter counts. The Mid Cont Snows are off 20% from their high in '97.
So winter counts are off 5%, yet equal or better flights than 05, means one thing! BUMPER hatch!
Also good maps on page 41 of the breeding and wintering areas in regards to different Snow populations.
