Some Bird Sounds from Bolivia
The following sounds are very short cuts taken from Sjoerd Mayer's CD-ROM
"Birds of Bolivia 2.0 / Aves de Bolivia 2.0".
- Horned Curasssow Pauxi unicornis, song. Recorded by Ross MacLeod, Bolivian
Yungas Project, Department of Environmental and Evolutionary Biology, Glasgow University,

- Huayco Tinamou Rhynchotus maculicollis, song. Also heard are a song of
Rufous-collared Sparrow Zonotrichia capensis and a song of Gray-bellied Flowerpiercer Diglossa
WAV file (59 KB) or
MP3 file (29 KB).
This species was formerly considered a subspecies of Red-winged Tinamou Rhynchotus
rufescens, but I discovered it has a very different song (see The Auk, Vol. 113 No. 3 July
1996, p. 695-697). This bird is often heard in the mountains of Bolivia, wherever there are
grassy areas on mountain ridges, at altitudes from about 750 m. up to 3500 m. It is not found
on the Altiplano, nor in the western mountains.
- Bolivian Recurvebill Simoxenops striatus, song. Recorded by A. Bennett
Hennessey. Also heard is the song of Olive Tanager (aka Carmiol's Tanager) Chlorothraupis

- Great Antshrike Taraba major, song. Included because it is such a funny song.
Also heard are the song of White-tipped Dove Leptotila verreauxi and various
vocalizations of Fawn-breasted Wren Thryothorus guarayanus.

- Yungas Antwren Myrmotherula grisea, song. Recorded by Sebastian Herzog. Also
heard are display calls of Yungas Manakin Chiroxiphia boliviana and short songs of
Gray-breasted Wood-Wren Henicorhina leucophrys.

- Masked Antpitta Hylopezus auricularis, song. Formerly considered a subspecies
of Spotted Antpitta H. macularius. Rediscovered by me in April 1994 just outside the
town of Riberalta, department Beni. It was first found in 1937 by Alfonso M. Olalla, only a
few kilometers from Riberalta, on the opposite bank of the Rio Beni. In 1945 Nils Gyldenstolpe
described it as a subspecies of Spotted Antpitta. I discovered that it merits species status
because of its distinctive song and habitat. I propose the English name "Masked

- Masked Antpitta Hylopezus auricularis, call. The calls of this species are very
distinctive. They are often heard at dusk when it is almost completely dark, but also serve as

- Giant Cowbird Scaphidura oryzivora, song. Also heard are a song of Plumbeous
Pigeon Columba plumbea (the yungas race with a very different song, quite probably a
distinct species) and a song of Dusky-green Oropendola Psarocolius atrovirens.
