I second what Dave said. Lmb normally wouldn't build nests that close together and...they all appear to be of about the same size. Lmb beds can vary in size a good bit. Just my opinion.
Dear Alcohol, We had a deal where you would make me funnier, smarter, and a better dancer... I saw the video... We need to talk.
Excerpt from Robert Crais' "The Monkey's Raincoat:" "She took another microscopic bite of her sandwich, then pushed it away. Maybe she absorbed nutrients from her surroundings."
Bluegill most likely but could also be RES or some RES could be at the margins. Below is a picture of a half dozen RES nests in my one acre RES pond that has no BG.
My RES nesting areas are in groups around the pond in different places because I do not have one big area like you have in your picture where so many can be together.
I also have some similar looking nests scattered on underwater humps I built that I would guess are SMB but they also could be RES. Hard to tell without seeing the fish on them and I can only see them when the water is low and the fish have left.
If you look closely in the last picture you can see a RES warily watching me wanting to get back on the nest (dark spot on the far side of the center circle). These pictures were taken a few weeks ago right around a full moon. About 4 RES were on nests that I could tell.
As far as the size of the nest keep in mind fish will clean out old nests and re-use them from previous spawns. I looked at the above nests just yesterday and they had no fish on them but some loose dead FA has settled in the middle. I fully expect these nests to be cleaned out and used over and over as time goes by.

Interesting. I forgot I added some RES several years ago and some more this year.
I wondered why a small fish would need such a large nest. Never thought of it being reused from year to year.
FWIW, I have observed large bass near this area on nest so shallow their fins were above the water.
