I heard this Carolina Wren singing and discovered it perched in my driveway! It let me squat down and not merely take its portrait but also experience a Serenade in my Driveway. They have a lovely repertoire of songs. These little round birds are common here in North Carolina but rarely sit out in the open and sing. I concluded he or she was serenading me in my driveway because he allowed me to sit next to him and continued to sing.
