What are these?

I was searching for pogonomyrmex here in North Dallas the other day and I know they like open nests so I started thinking of a baseball diamond because they have good drainage and tend to stay dry. The field I was searching in was full of fire ants but I did see this humble mound, definitely not fire ant. I know it can be hard to identify without a microscope or a clear view of the gaster. Here is the video:

a good way to ID them would be to catch a worker or two and take pics at your house

you mean like a macro shot with digital zoom? or in a test tube

macro shots would be nice and do you know the size of the ants
