Each winter the ponds and lakes in Falmouth fill up with all kinds of wintering ducks.  Rarities pop up from time to time in different locations.  One of the regular rarities is the beautiful Eurasian Wigeon which tends to be found in flocks with their similar looking North American cousin, the American Wigeon.  The Eurasian Wigeon has pale gray flanks and wings, a pinkish brown chest, and a rich chestnut head with a buttery yellow forehead and crown.  This rare Wigeon can regularly been found at the Mill Pond in Marstons Mills.
