The winter scenes I see in the Delta are mostly about waterfowl. Webb Tract is home to many thousands of waterfowl in winter. Aleutian geese, white-front geese and snow geese are most common.

Sandhill cranes were fairly uncommon 35 years ago, they now are very numerous.
Ducks were the most common waterfowl inhabitants, habitat change has reduced their numbers today. Corn fields and sand hills are most attractive to geese, especially white-front geese, often called speckle-belly geese.
Tundra swans were numerous 30 years ago and since declined, but the last couple years they seem to be making a comeback in the delta.
Yesterday was a quite day. No shots were heard on my visit. Except for a few birds here and there in the air, the birds were on the ground, avoiding the wind. I few flocks of geese, that objected to the presence of my pickup, took to the sky for a few minutes and then landed.
