Yikes! This is what comes from wanting to crow too soon! After returning home and double-checking our notes against a guide (we didn't have a field guide with us), we realized our two Ammodramus sparrows had distinctly gray median crown stripes (not white) and no stripes on the solid gray nape. This is only our second sighting of Nelson's in our 22 years at the farm. Susan McWhirter Rock Island Warren Co.
