So I have 2 hanging baskets on my front porch, 1 basket is looking real shabby. I've been monitoring a Carolina Wren's nest; today I was able to see exactly what is going on w/the nest.
Wrens make huge messy nests; last year I had one build a nest on a shelf in the garage, the bird wrapped the nest around the handle of a weed eater.

Carolina Wrens are sweet little birds, great pictures.
