QS,
We've had Rio's here since the mid-late 50's. So far the only spring season is on the Big Island. The best guestimate is that we have 33,000 birds. Jan & Feb of last year my NWTF chapter helped the state release 16 turkeys on Oahu. Last spring we saw 10 chicks in the 3-4# size range. If we can get a decent population on Oahu plus the one on Kauai; in a few years we might try to develop an award for a state slam (a tom from Big Island, Oahu & Kauai). That'd be cool.
