We definitely prefer the "artsy" style bird more than the one in #88, and very much like your thinking about "nesting". That's thoughtful and smart, but I'm not sure it carries the design enough to have an impact. I like #95 the best, but am concerned that the bird might not be recognizable enough to catch the eye on a yard sign or to build a character off of. I do like it, but....I'm just not sure its quite the right one.
Maybe try a different font color so that the bird stands out a bit more? Maybe red and black, or just black with some other red element incorporated into the design? Or just red?
Also, I think I prefer the bird on the "r" rather than the "n" but it may change when the font color changes.
What if the bird is a bit less artsy. Maybe add an eye? Or a bit more shading?
