Another wooden trunk between some old rice fields, this one controls the flow of water from the canal in the foreground to the impoundment behind that dike. This set of trunks was replaced last year and only this side has the full pivoting door mechanism.
I knelt down to get the next image, where you can see open water in the impoundment on the other side. The grackle and the Tricolored Heron had moved on and the juvenile night heron took that opportunity to claim a post.
