I may be able to access the full text on moday via institutional log-in. After reading the abstact a couple times now, it seems as though they might be implying that there is no validity to current differentiation of the subspecies sirtalis sirtalis and sirtalis parietalis and that they are based solely on color differences, so maybe the arguement on this post is moot. Also, are they implying these locale flames deserve unique new subspecies status? Kinda looks that way doesn't it?
Guess I may as well cross my albino red-sided to my erythistic albino eastern next spring and see if they are compatible albino types huh? Just kidding....or am I ? lol, would it be CBB hybridizing or not? lol how about that can of worms? Maybe we should just lump all thams into one species, then I can get started working on making silver granites, granite albino flames, green axanthic granites, and green axanthic granite piebalds, oooh that would be cool, patches of green and black flecks on a mostly white body.
