Winter colour - or gratuitous ducks

I went out for a walk yesterday to a near by pond. The day was grey - the iridescence in these feathers provided the only natural colour around. All these ducks were hanging out hoping for food. Their wait paid off as many walkers (us included) brought duck snacks.
