This is the grass fed on by a migrant Painted Bunting in our yard (4/15/24).
Grid on backdrop is 5 mm squares.

I compared these images side by side with the F. pubescens in my yard and the reticulate venation on the underside of leaves (second image) is conspicuous. BONAP maps reticulata in adjacent counties but not in Kimble.
Had such a blast with other iNatters at the Del Rio gathering. I saw lots and lots of new plants and animals -- so these ID's are tentative. I'll have to do a little more digging later.
