We have pair of Carolina Wrens building a nest in the holly bushes right outside our front door.  And this Wren parent is busy making the nest extra comfortable.  Seems that both parents work on constructing the nest.  There’s a good description of exactly what’s going on on Cornell’s All About Birds site; scroll down under ‘Nesting’.  If they choose this nest, we’ll be using the back door for a while.
