30 Cotinga 22 Study site Amazonia Lodge in south-east Peru is a popular tourist destination for birdwatchers and eco- tourists. The lodge (12 o 52’S 71 o 22’W) is situated between the río Alto Madre de Dios and the Pini Pini Ridge, at km 192 on the Cuzco–Shintuya road, in dpto. Madre de Dios. This location is inside the Cultural Zone of the Manu Biosphere Reserve, at 514 m. Atop the Pini Pini ridge, just above the lodge, is a large landslide (12 o 52’S 71 o 23’W) that has cleared an area from the top of the mountain to the river below (Fig. 1). Although present since at least 1978 (R. Yábar pers. comm.), it has only a few spots of young secondary vegetation and is mostly bare due to continuing erosion. Birds were observed from the top of the landslide, at 888 m. O bservations In June–July 2002, I made seven trips to the landslide. All birds seen and heard were recorded (Appendix). Yellow-cheeked Becard Pachyramphus xanthogenys and Streak-throated Bush-tyrant Myiotheretes striaticollis were observed and photographed on multiple occasions. P. xanthogenys has not been recorded previously in dpto. Madre de Dios or this far south. M. striaticollis is not typically found at elevations this low. Neither had been previously recorded at Amazonia Lodge 10 and these records bring the list of birds known from Manu Biosphere Reserve to 999 (B. Walker pers. comm.). Yellow-cheeked Becard Pachyramphus xanthogenys A pair observed in scrubby vegetation within the landslide. The female was seen 27 June, the pair on 2 July, a male (and possibly a female) on 8 July, and the pair on 11 July. Photographs were taken on 2 and 11 July (Fig. 2), and I tape-recorded the male on 11 July. The female was first observed briefly at close range. Field marks included a rounded, grey head with yellow eye-ring surrounding a dark eye, yellow breast-band, white belly, and solid olive- green back, wings and tail. Further details, such as the chestnut shoulder patch, were seen during subsequent observations. Field marks observed on the male included a black cap, white lores, unbarred yellow cheeks, throat and breast, white belly, and solid olive-green back, wings and tail. Streak-throated Bush-tyrant Myiotheretes striaticollis One photographed at the landslide on 18 and 27 June, and 1, 2, 8 and 11 July (Fig. 3). It sallied from rocks or low perches, and sometimes beat captured insect prey against rocks. In flight, this species and Cliff Flycatcher Hirundinea ferruginea both reveal bright cinnamon-rufous patches in the wings and tail. Both were present at the landslide, often for side-by-side comparison. M. striaticollis was distin- guished from H. ferruginea based on its larger size, streaked throat, proportionately larger head and stronger bill. Also, the belly of M. striaticollis is a paler or brighter rufous than the more chestnut- coloured belly of H. ferruginea. M. striaticollis had faint wingbars and pale edging to tertials, whereas H. ferruginea did not possess any sign of wingbars. First record of Yellow-cheeked Becard Pachyramphus xanthogenys in Madre de Dios, Peru, and notes on birds from the same locality Daniel J . Lebbin Cotinga 22 (2004): 30–33 Este artículo informa sobre las observaciones de pájaros dentro de un derrumbe encima del Amazonia Lodge en el sudeste de Perú. Una pareja de Cabezón Cachetiamarillo Pachyramphus xanthogenys se observó cuatro veces en este sitio. Estas observaciones y una espécimen de museo no publicada representan los registros del extremo sur para ésta especie, y los primeros registros en el dpto. Madre de Dios. Un Alirrufa Gargantilistada Myiotheretes striaticollis se observó también varias veces en este sitio que, a 888 m, es más bajo que la elevación típica de esta especie en Perú. Los orígenes de las aves en el derrumbe se discuten también. T able 1. Published 1,7-8 altitude distributions for five species found at 888 m, at Amazonia Lodge.
