As I approached the area where I’ve been seeing Carolina Wrens lately, I wondered what it was about this spot in the dead of winter that they liked so much. Food? Shelter? Starbucks? Before I could propose some ridiculous theory, the answer revealed itself. Heat! There in the bank of a small drainage ditch were two tiny wren sized dimples, and I only know that because, right on cue, a wren plopped down in there and practically melted before my eyes!
