Day 2,861 —Ducks on a Frozen Pond— with my PICTURE a BUTTERFLY #645

Today I went to take pictures of the frozen pond, and I saw some ducks sitting in a spot that had an opening. The gap was the size a hula-hoop. The image reminded me of something I had once read. Isn’t that something that someone talks about in a book? Where do all the ducks go when the ponds are frozen? 

I am sure I will remember where it is from.
