A bird survey of Torcillo-Sarayoj, the lower Yungas of Madidi National Park, Bolivia A. Bennett Hennessey Cotinga 22 (2004): 73–78

Mediante observación y grabación, realicé un estudio extenso de aves en el sitio prístino Torcillo- Sarayoj del bosque Yungas inferiores (EBA 054) de Parque Nacional Madidi del 6 al 17 de octubre de 2003, entre 1.600–1.800 msnm. Registré 156 especies de aves. El sitio tenía una posibilidad de 276 especies en relación a su ubicación y hábitat. El bajo nivel de diversidad encontrado puede ser un resultado de la ausencia de Yungas arriba de 2.000 msnm. Por encima de Torcillo-Sarayoj se encuentra el bosque seco y sabanas de la región de Apolo. En cuyo lugar no encontré las posibles especies amenazadas en el área de Pauxi unicornis (ni tampoco obtuve información local del pueblo de Sarayoj) y Terenura sharpei. La única especie amenazada en el lugar es la Paraba Ara militaris, que es común en los Yungas de Madidi. Además, encontré seis especies de rango-restringido de de 12 especies posibles. En conclusión, dado el pobre nivel de diversidad existente de aves en el lugar, es de gran prioridad realizar estudios en el oeste de la región de Torcillo-Sarayoj para verificar la zona más viable de los Yungas inferiores en Madidi y Bolivia.

In recent years the Yungas of Madidi have produced Birds were observed, sound-recorded and identifi- a number of avian range extensions and other cations verified using pre-recorded tapes or discoveries not predicted for the area3,5,10.

Given the conservation priority of the tape-record all species at least once. Each evening I lower Yungas EBA14, it was imperative to conduct completed a checklist of the day’s observations, an initial rapid ornithological survey of the Torcillo- noting estimated abundances, field time, distance Sarayoj site.

Methods On 6–17 October 2002, I surveyed the lower Yungas forest at Torcillo-Sarayoj (Fig.1; 14o37’S 68o11’W, c.20 km east of Apolo), at 1,600–1,800 m. Torcillo- Sarayoj is a pristine lower Yungas forest, with the eastern, higher slopes above 2,000 m reaching Apolo valley dry savannas and dry forests. Part of the study area is on a slightly sloping plateau area at 1,700–1,800 m with old-growth forest. Below 1,700 a fairly steep slope had younger forest. The area was accessed via a trail to the village of Sarayoj, on the valley floor (1,200 m). Three camps were established for the survey: at 1,750 m, on 6–9 October, 1,700 m, on 10–13 October, and 1,800, on 14–17 October. I followed the trail to 1,600 m. Survey work was conducted on the main trail and Figure 1. Map of the western Yungas forest, dpto.

Thereafter, I surveyed different based on work by the South American Checklist trails, covering 1–3 km, and usually halting field Committee of the American Ornithologists’ Union work between 12h00 and 15h00. I used binoculars, (www.museum.lsu.edu/~Remsen/SACCBaseline.ht sound-recorders and pre-recorded reference tapes. ml, version 13/09/2002). The pre-recorded reference tapes were designed for the Bolivian Yungas, with examples of songs and calls indicative of individual and regional variation.
