Very small. This seems a little too compressed for C. pustulosa but nothing else seems to fit better.

Medium high frequency buzz from a tall prairie grass patch along road. Fairly broad spectrum 6-8 KHz, with a peak at 6849 Hz; pulse/chirp period 4.8 ms (208 Hz). Different individual, but probably same species as https://www.inaturalist.org/observations/232144385

Found dead in sand at the edge of a recently built man-made "swimming hole" pond (fed by well water and runoff) on private property, along with some dead and sun-bleached duckweed. The pond was first filled last year, and it has many insects and amphibians but few plants. Its bottom is a mix of mud and sand. Max depth is about 6ft/2m. It is about 20ft/7m above and 200 feet away from a natural intermittent grassy wetland in a depression.
Ten pairs of valves, still connected, from about 3.5mm to 5mm length.

After looking for the source of all the Corbicula, a few friends (including @daniel56628) and I found a lot of Corbicula next to a stormwater drainage pipe.

Repeated upward whistles (low to high on musical scale). Intermittent brief chittering sound and periods of silence. Mostly the consistent whistle call.
Did not see the bird.

A small, 3mm valve found in mud at the edge of a rock/gravel-bottom stormwater retention pond. The 4th photo compares this valve to a Euglesa compressa I found at this same location

A new genus for me. A single 3mm valve found in the mud at the edge of a stormwater retention pond. I wasn’t expecting to ever find this genus here so I’m pleasantly surprised.
Photos 6-7 are taken in situ

Swimming slow enough to catch it with a small net. When released, it started swimming upside down.
