Here are five photos that I took from Village West Marina of tule fog on White Slough in Stockton, California. Tule fog is common here in The Delta in the winter season. The blue heron seems to a patience hunter in the dead tree branch along the levee.

Lovely photos of the blue heron perched on the tree limb in the Tule Fog!😊
Thanks for your comments. The blue heron seems to have found an ideal spot to hunt for dinner in White Slough.
