Thanks CK, that's the one all right
. Also, I'm not in NV, that is just one of the quirks of satellite internet, I'm in Eastern Montana. These birds are up on the flats above the Powder River valley.
According to Wikipedia, they are water birds or more specifically shore birds but they fly to the grasslands to nest. I don't know if I've ever seen them before but there is kind of a little flock of them here this summer. I came across a nest as well and their eggs are as large or larger than chicken eggs.
