Wrens are one of my favorite bird families. Our local representative is the Carolina Wren (Thryothorus ludovicianus) whose song resembles a pleasant car alarm [listen]. In a recent paper by Eric Fortune at al published in Science there are several recordings of Plain-Tailed Wrens (Pheugopedius euophrys) from South America singing what are obviously coordinated duets. I’d love to have these in my backyard!
