Have not seen any migrating Red-breasted Mergansers this season, so as I was editing some past images, I came across this one which was captured on a local lake. This day there were plenty of Red-breasted Mergansers fishing in close proximity to Double-crested Cormorants. These three might have picked up speed as they passed the Cormorant. C&C welcome.
