The reason for the low numbers (if you believe in them) is habitat. If you hunt private or public and there is good habitat you will see birds. I know this report has been debated on this site many of times... I tend to believe the people/farmers out in the field vs. someone driving by 2x in a 20-day period to count pheasants. Its been going on 5-years since I bought my 160 and I can tell you the bird numbers have exploded, why? Habitat (trees/wintercover, food plots and nesting cover). My friend was out doing some maintenance on some of our new trees and he said the # of chicks were crazy good. Appear to be all different sizes. Again, I know who I believe... Call the farmer, he will tell you. One quick comment on the road survey... We all have had honey holes in years past that dry up and you think what happened.. Turns out the pasture across the road was plowed up, the slough was farmed and now its corn and beans... How can these same routes they have been driving for years not experience that same sort of change in farming. If you look at the reported decrease its fairly uniform. Do you think the whole state of SD had similar weather (winter/hail storms, to much rain etc.,)? no way, to me its simple... loss of grass/cover
