Please sir, may I have some moss?

Today on the nest I lined the edge with some moss. I also collected trash that was out in the woods. Mostly in the form of styrofoam. I hate styrofoam.

To line my nest with moss I assumed that I would have to remove debris from the ground and put nice squishy mud from the edge of the creek down first. And then gently place moss on top of it. I'm not sure if it will survive the rest of winter. But I'll try to help it along. And if anything I'll collect more when spring rolls around.
