The Carolina wren hopped on the fence and sang so sweetly.  This was unusual behavior by this bird but there was a nest they planted ten feet away in a wandering Jew plant hanging from the middle of the garage.  Now I knew what they sounded like.  More than once we saw the birds fly from the nest.  Several times we saw one with a worm in his/her mouth.  I could not hear any babies.  It appeared as two birds were flying back and forth from the nest.  The nest was facing the door and my wife was careful not to disturb the birds when she watered the plant.  Now I know what they sound like.  It seems as if every year some bird nests nearby our front door.
