It's turned sharply colder, but it's also the start of duck courtship season, so, in the still un-refrozen stretches of the local rivers, splendid Hooded Merganser males are fanning their head crests in the hope of attracting the attention of the less-gaudy females. This pair, however, has what looks to be a chaperone to keep amour from getting out of hand. Strangely enough, the watcher is a member of a different species known as the Common Merganser, or, to use their more-English name, the Goosander. It's probably just coincidence that the three birds are together. I don't know what would happen if things got randy.
