Mr. Molting Wood Duck got a bit startled by Miss Mallard who was most definitely going to preen on her favourite rock. He moved over and gave her some space but she insisted he get off completely.
The water nearby was quite shallow, so he decided to hang out there instead. And, since he was now a bit closer to me, I got a better picture! You can see some pin feathers where some of his wing feathers haven’t grown in yet. I had a bit of trouble imagining which feathers were missing so I looked at many, many Wood Duck images on the interwebs. The second picture on this page (bird photography by J R Compton) cleared things up for me.
Mr. M.W.D. before his rock peace was disturbed.
