Juvenile mallard ducks are quite interesting because of the blue mark on their wings. I always get excited when I see that- thinking it could be some type of teal, wood duck, or other interesting duck species. Nope- just a juvenile mallard!
These pictures were taken in Plymouth, MA at the beginning of the pathway that goes to the to the Jenney Grist Mill. Steve and I went for a random drive and walk around Plymouth back in mid-October. We live so close! There's really a lot to see and do there, and Plymouth Harbor is also a great birding spot. I saw the Ivory Gull there back in 2009
