Happy Wren
Pheugopedius felix
There is little difference between the sexes as adults. They are fairly typical small wrens, with a black and white striped face, a downward curving bill, chestnut upperparts and cream underparts. Howell and Webb give its length as 12.5 – 14 cm. Voice: Like many wrens, happy wrens produce a complex song, described as a "rollicking, gurgling whistle." Songs are less varied among island populations. Pairs of happy wrens primarily use their duet songs for cooperative territory defense.
