Ducks, geese and swans on an artificial pond in Cedar Rapids, Iowa appear to huddle for warmth as their water freezes. Actually the pond is regulated with a filter and pump to allow the fowl to remain on site year round. Attempts to feed the flock were disregarded by the masses of ducks in return for bunching together. No amount of bread crumbs enticed the birds to venture near. There loss. Maybe the omni present squirrels will find the food.
