Dove crop analysis

[shinbone]

Me and a buddy went dove hunting this morning near Sterling. Super slow shooting, but we did manage to scratch down a couple. This is a photo of the contents of one of the dove's crop. The penny is for scale. Can anyone identify any of the seeds? The majority of the seeds are small black seeds that look like black peppercorns, but smaller . . . ? TIA

There are so many grasses and weeds that they eat, it is hard to say. I am no expert, so they all elude me. I see little milo and sunflowers, though, which is what many doves eat. Opportunistic feeders.

Good luck with the seed ID!
