Happy Hooded Merganser drake, from last month. Cloned out several of his fellow hoodies. This species eluded me for a number of years, but I finally managed a few moderately close frames of him including this one with open mouth and full crest.
D7200, 500f4 + 1.4 TC, ISO 1000, 1/2000s @ f/7.1 manual.
