I haven't seen anything happening on that board in 2 years, it has literally died. Posted some questions 6 or so months ago and no one even viewed them.....
One interesting thing I have noticed witht he silvers is the colour difference between the males and the females. The males are always a very light powder blue while the females have a much more steel grey/dark blue cast to them. I have noticed that both on the silver tuxedos and silver wild types.
As for blue. I wonder if they call silver ranges -blue since that is almost a solid blue bird. The silver tuxes with minimal white are great to look at since the blue has no striping or pattern on it like with the wild type silvers where you see the stippling etc.
