The rare-for-our-region Harlequin Duck comes in for a closer inspection. From my prone-on-my-belly low angle approach the mallards kept crossing between me and this gal, blocking the view. Luckily I had brought tasty treats for them and threw some hard to my left to get them out of the way. That worked like a charm, paving the way for a clear look at the Harlequin Duck through the lens. As you can see, the light came from the left, and this head angled splashed the light just perfectly onto the face.
Amazingly the brouhaha caused by the mallards fighting for food caused her to bee-line it straight towards me to investigate. An unexpected and very welcome surprise. She turned around and came in a second time too...even closer!
