As I said previously, most people who get "lots" of bands are hunting near refuges where banding occurs. That isn't to say that we all don't get lucky and sometimes knock down 2-5 in a season, but for most of us it isn't that often. I kill around 100 birds/yr and for me, I don't get "lucky" that often.
I'd love to hunt near a refuge where I could get a few more chances at bands, but it ain't happening right now.
I know guys who shoot near refuges in the midwest in Wisconsin, MN, Iowa, Illinios and Indiana and they shoot many more banded birds than anyone else I know.
I stand by my rough estimate that about .5% of our birds we see are banded, maybe it is .3% or 1%, but its close to about .5% at any rate.
Heck, one of my buddies shot a double on the last day of the season last year...two banded drakes
Sometimes ya just get lucky!
