Given the winter prevalence of this species in California, I cannot believe how long it took me to capture a solid on-water image of this stunning duck. The on-water frames I had from my early photo days (2011) weren't as sharp or as well-exposed as this example, and all I managed in the nine years were flight shots. So yeah, this shot was long overdue!
