I drove through Rock Cut SP around 3:00 p.m. on my way to a meeting elsewhere.  The lake was full of boaters, paddle-wheelers, kayaks, etc., but a few birds were also present.  Most notable were 6 Rough-winged Swallows, new migrants to the area this spring.  They were flying around with a much larger number of Tree Swallows, which are continuing to build in numbers. 

No sign of the Osprey that Steve Gent saw this morning, but 2 Bonaparte’s Gulls were on the lake (and flew off while I was watching), about 12 Ruddy Ducks, some Buffleheads, 1 Ring-necked Duck, and a couple of Pied-billed Grebes.
