American toads. They get trapped in the ground wells( for checking continuity of the sites grounding ring, under ground) often.
Edit: Added a picture of a ground ring. The well is a spot that is accessible from above. I usually remove the gravel around them if I can, to make the sides taller. And I put a rock in the hole on top. A lot of companies are moving away from this tipe of cover. Sometimes the lid is just missing. I guess I could get some screen but that would probably get pretty expensive for me. I check the wells at every site go to. Rescue as many as I can.
Thank you! That is much more clear! I was probably just searching the wrong things.
It looks high for them to jump into for no reason, and not like something they’d just wander into because there isn’t anything to keep the sun off or trap moisture if the cover isn’t on.
I’m sure the bumpy lil guys are glad you check for them!
The gravel was a lot closer to the edge before I kicked it away.
Perhaps they just sense the humidty then and assume the inside is ground level.
