Hey Hunter,
As much as I don't like to cross-link to other Forums, here is a nice Bird & Trout knife thread with a lot of examples to draw from. If nothing else it illustrates how many different designs are considered "Bird and Trout":

Also if you google for "bird and trout knife" and look at the images tab you will see a lot of great examples. I don't think it's coincidence that the first two images brought up in Google look suspiciously like the two images that Ray posted.
Good luck,
