This bird has wintered with a flock of about 30 Robins in the area between the Duxbury school complex and the back portion of the Duxbury Yacht Club's golf course which includes the little Alden Sanctuary (currently unmarked). The photo shows its white underparts, leg feathers and rump. The chest is also quite mottled with white as is its throat (more visible in life than in the photo), and there are bits of white on the tail (though it is predominantly dark).
