Found this specimen a while back and thought it looked really odd for A. americanus (Hence why I photographed it). Coming back to it now with a bit more knowledge I can see it shows structural characteristics more like the Canadian Toad--Two closely-raised ridges between the eyes forming a blunt crest. The wart and colour patterning also look different and give off a slightly different impression.
That being said, I still have little-familiarity with this species. Plus these aren't known from here in Ontario. Looking forward to any thoughts and input
