An insect nest made of mud. The entrance was about 1 inch wide and the whole mound was about 3-4 inches high. I assume it’s some sort of mud dauber wasp nest, but I don’t know.

Looks like a crawfish burrow to me.https://blogs.ifas.ufl.edu/escambiaco/2020/05/13/weekly-what-is-it-crawfish-mounds/
The mud dauber wasp builds tube-like nests instead of digging. It looks like this nest is dug up on the ground. Insects also do that, but perhaps not in wetland areas. I know that some species of crayfish do that https://adoptandshop.org/exploring-the-u...
