Black-throated Wren

Pheugopedius atrogularis

Small24 gForest

The black-throated wren is 15 cm (5.9 in) long; males weigh 24.3 to 27.3 g (0.86 to 0.96 oz) and females 22.5 g (0.79 oz). Adults have dark reddish brown crowns and upperparts that are redder on the rump. Their tails are blackish brown with faint buffy markings on the other feathers. Much of the face is black with white markings. The chin, throat, and upper chest are black, the mid-chest is reddish brown, and the lower chest and belly are reddish chestnut. Juveniles are essentially dull dark brown overall, with less contrast between the upper- and underparts than the adults. Voice: The black-throated wren's song is "a distinctive series of rich whistles ending in a trill" . Its calls include "a fast, nasal to wooden rattling 'praaaaht'" and a "guttural rolling 'beewr' or 'bweeurr'".

Plain-tailed Wren

Pheugopedius euophrys

Small30 gForest

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.
