Very Small Feather Collection from SF Bay

Monday, October 19, 2020 was a day for seeing lots of tiny feathers floating on waves in the San Francisco Bay and landing in among the reeds and other detritus on the beach. Since it was a windy day and impossible to photograph these feathers in situ, I brought them home to photograph and measure them, then took them back where I found them.

There were hundreds of birds swimming on the water, including: coots, pied-billed grebes, mallards, cormorants, and others.

All of a sudden, dozens of birds took flight. There was a disturbance in the water. Then we saw a harbor seal! I've never seen one this far south in the bay. What a treat! But the birds didn't think so.
