Maybe Lisa can answer that one, but I have found American toads in the evening so my guess is that they are crepuscular rather than strictly nocturnal. I also imagine the urge to mate overrides normal behaviors!

Just wondering: In my experience, Fowler's toads are diurnal, and easy to find during the day. American toads are nocturnal, and I hear them much more than I see them. Do they change their habits during mating season, or is their temporal separation part of why hybrids are uncommon? Or am I wrong about when they are active?

I was really lucky as my friend Lisa Power's is a herpetologist. Lisa was with me when we found this guy otherwise I would never known he was a hybrid!

drpalombella, I understand these hybrids are usually infertile.

Cool! I didn't know they hybridized. Do you know if the hybrids are fertile?
