I must admit, I wouldn't have recognized him with his head down. Or even seen him. I spotted him because he peeked up when a teal went swimming past. I managed to get this shot, then he ducked down again. I reported him to the others, who'd been watching a pair of loons way further out on the tarn. One guy noticed when this duck flew off and was sure it was something else. I forget what he thought it was, but he was quite insistent. So I scrolled my way back to this shot ... ID definitely confirmed.
