Does it have a long neck? How tall is he? It was near the water?

The only bird that I could come with a Killdeer:

It occurs throughout North America that usually near water. Is it?

Ok well the two black bands may vary in size and may not be visible from afar. The Killdeer is a plover to verify this and see if one of them is the one you saw:
