Bobwhite?

On Friday morning, in the front of the upper garden, I heard "Bob White ... Bob White." Nothing more, and I didn't see the speaker. Mary Lou was not far away and didn't hear this .... Still, what else could it be. I spent some time there again this morning, with no luck.  Lots of hummingbirds, and the pond was active.

New odonts, both from the upper field:

Black-shouldered Spinyleg

Meadowhawk
