So tonight I walked out the front door to go throw apples out to the edge of the woods for the deer. We have a little sidewalk across from the front door that I have a long mulched flower bed against it. I did not see this nest yesterday, so it is new. I see not a thing flying around it. It is raised about 1 and half inches from the ground width of it is about 3-4 inches. The hole is centered and about an inch wide or slightly less perhaps? In all the years at the farm, I have never seen a nest like this and I have seen many yellow jacket nest in the ground in the pastures...but this?????? It almost resembles puppy chow with a hole in the center...and no, my dog was not in that area.,..or any other dog. HELP!
Would a hummingbird do that?
Meanwhile I am going to be watching it with binoculars in the morning to see what the heck made it.
Moles do leave dirt around the hole.
Legend, Wow thats some video!
Well not a thing came in or out of that hole that I could see, so I slapped a huge rock over and went to work today. I took the rock off when I got home and it was just smooched. Covered it up with dirt/mulch and it looks like whatever it was has vacated or whatever. I will look again in morning. I am also allergic to bees and have Epic-Pens everywhere, so I am very careful. 
Maybe I need to buy a drone ? And yes moles pile dirt, have seen that before when we had them in the yard at last house.....several mounds, but none that looked like this. So am still not certain what it was. I do feel bad if it was a solitary pollinator bee, but geese, they can make their home all over our land, just not where I work in my flower beds
