Plain-tailed Wren
Pheugopedius euophrys
Voice: The plain-tailed wren sings a rolling, repetitive song. Singing pairs of plain-tailed wrens coordinate such that the duets between males and females alternate syllables so quickly it sounds as if a single bird is singing. Research finds the brains of both birds process the entire duet, not just each bird's own contribution.
