Visited my folks in South Dakota a few weeks back. I was a little early for the big migration of shorebirds, but waterfowl were still very much present. American Avocets are one of my fave shorebird species, and luckily they were around in fairly nice numbers. Also got to see some Black Terns - mom was still feeding some of the kids. And Upland Sandpipers are always ones you look "up" to find - they are usually on telephone poles or fence posts instead of at the water's edge.
