What is making this mound?

Asked April 4, 2016, 3:34 AM EDT

Does anyone have any idea what kind of critter is making this mound? Its just one mound, made with mud balls. Hole is open in the morning & all day long, it does some excavation (building higher) during the day and then closes the hole at night with mud balls... The "mound" started about 4 or 5 days ago. I'm sure its not a gopher or mole... anyone have an answer or guess? I've tried to identify whatever it is from online pics to no avail. Thinking about digging it up!! The mound is now about 8 or 9 inches high.

There are a limited number of animals that make such mounds. I suspect a gopher or ground squirrel. But I'm leaning strongly to the gopher. Neither animal is a welcome guest. The texture of the diggings is a reflection of the soil through which the animal is tunneling.The UC Davis IPM page "How to Manage Pocket Gophers can be found here: http://www.ipm.ucdavis.edu/PMG/PESTNOTES/pn7433.html

The next link is to the Ground Squirrel page.
By all means, dig it up. You don't want to be welcoming. They will bring all their relatives to dine at your expense.
