finding food on ice

It seemed like all the ducks were trying to find something to eat and they they kept walking all over the ice flake, nipping here and there.
At least they didn't care that I was watching.

I took the photo through the bars to add a feeling of imprisonment, I think I felt that their search was quite fruitless.
