I photographed this Pied-billed Grebe on 4-7 in NE Ohio. It was swimming near some coots and buffleheads but no other grebes that I could see when it would stretch its wings out and hold them in this position for a short while then slowly pull them back in. The grebe is in breeding plumage but the behavior looks like more of a threat display than courtship, or was it something else?
