I like what joebuck stated, that essentially you may be able to work far more birds without a blind versus with. However, calling a bird within range is a far cry from shooting one with a trad bow!!! I've personally never been able to draw a bow in front of a bird without all hell breaking loose!! I have killed quite a few birds from a blind however. Don't think just because ur in a blind that the birds are going to just sacrifice themselves!! I've missed far more than I've hit and I'll continue to hunt them from a blind because there is still nothing more exciting than having a big, old tom spitting and drumming as he closes in on you!! Good Huntin'
