spot-breasted thornbird Phacellodomus maculipectus

Shy understory bird of upper humid montane forest in the east slope of the Andes from central-western Argentina to central Bolivia. Prefers thick understory, and more often heard than seen. Often curious and inquisitive, but tends to stay hidden when possible. From similar Streak-fronted Thornbird by reddish cap, spotted underparts, and habitat (Streak-fronted prefers dryer and more open woodland). Song an accelerating then decelerating series of 10-12 “queet!” notes that rise and then fall in pitch.
