I went and looked this afternoon and got good looks of the same 2 plovers in flight. They are Black-bellied based on having light rumps and dark axillary coverts/wingpits.
There were also Dunlin, Dowitchers, and Stilt, Least, and Semipalmated Sandpipers still present. The Dunlin count was up to 8 but there was only one Stilt Sandpiper today and drastically fewer gulls and Least Sandpipers.
Based on a discussion on the Idaho Bird sightings and discussion page, these are probably black-bellied plovers. That was based on Bill size, more in distinct supercilium, breast streaking instead of barring, and whiter bellies instead of gray bellies.
This past Friday, Big 71, prime number so I can’t split it.
I also just realized something. It was one thing to send a copy of the cartoon to individuals, but, I put it on a public forum. There could be complications, permission not given etc.. I’ve sent Cliff a note to remove the post to keep me as well as ible out of any trouble.
