From John J. Collins:

The previously reported CLAY-COLORED SPARROW is still present at Duke Farms right now. It is located in the weeds bordering the west fence located in the community garden parking lot (said gardens are west of the visitor’s center f/k/a the horse barn). Dozens of AMERICAN GOLDFINCHES, SAVANNAH SPARROWS, PALM WARBLERS, at least 2 AMERICAN KESTRELS and many other species are present as well.

I also think I am hearing a WHITE-CROWNED SPARROW singing right now.
