The fog was thick this morning, no visibility thick.
This was my first trip to these marshes since November. The roads and trails are closed to protect migrating birds.
Tundra Swans, from the arctic winter here. I heard plenty out in the fog.

A back trail was open to vehicles so it was worth staying even with the low visibility.
I found a Tricolored Heron in an area with a bit less fog and watched him fish, or try to, for a while. The Heron couldn’t see either and he was pulling out all the tricks.

Tricolors run around, wings extended, to scare up small fish. The extended wings provide a shaded area over the water, Makes it much easier for the bird to see movement.
It didn’t work but he made a good effort.
