It's not the highest factor on my list, but it is a factor to me that this TRC will be seen by people who may not be as familiar with the PRS brand as some of us are. With that in mind, I just chose the eight that I thought looked the best on their own as well as part of the whole design. The actual amount was just the way it turned out. I guess it could have been done with only four birds, but I liked the message that eight conveyed. We forum members and PRS fans are all over the world, yet we're still relatively small in number as far as guitar companies - and their fans - are concerned. Using every bird wasn't high on my list, or even which birds; I just used what I felt were the best.
As for which bird species you're referring to, I honestly don't know one from another, although I've looked at the list plenty of times. But I can identify them this way on my layout: The bird under the f-hole, and the one under the 12 in '2012' (or at 8 o'clock and 4 o'clock) were my last choices because they were the "least best" examples of the eight I started with if that makes any sense. If you have an idea about using different birds somewhere, I'd like to see it. I'm for whatever makes this whole adventure work out for everybody.
One more thing if you don't mind. I want to apologize to everybody for slowing down the process because I don't have an image hosting acct. somewhere. I realize it's a pain to have to deal with me in this, and I really appreciate everybody's patience and indulgence. I can't thank you all enough for letting me take part.
