Weed Identification

Do you have persimmon tree in your yard?

It does look like a tree/shrub sprouting from seed/roots.
If from seed, mowing will likely kill it.
If from roots, might need a treatment with stump killer or tree control product.

Looks just like the ones popping up in my yard up to 30 / 40 ft away from the persimmon tree. Sadly, the root stock is a mundane native seedling and the main tree consisting of several several named varieties doesn't look nearly as healthy as the root suckers.

Is this your first summer at the house? Are these new after several years at your place? If root suckers, they are awfully well distributed for the first time showing up

That’s what it is. Likely Robins or Starlings.
