I was at my brothers place on Sunday afternoon. The snow had melted by then and the sun was out. Up in an old Crabapple tree a pair of Red Breasted Nuthatches were busy burrowing into the tree to make a nest. They would take turns going into the tree, you could hear the tapping of their beaks and then they would pop out of the hole with a beak full of wood shavings and drop them to the ground. I enjoyed listening to them chirping away as they worked.
